[0072] The embodiments of the present application are further described in detail below in conjunction with the drawings in the specification.

[0073] The existing construction data lifecycle management and control methods based on digital technology are effective for traditional construction projects, but it is difficult to effectively control and coordinate construction data in new environmental protection construction projects. As a result, the application of construction data lifecycle management and control methods based on digital technology in new environmental protection construction projects is limited, resulting in imperfect construction data management in new environmental protection construction projects.

[0074] Based on this, the present application provides a BIM-based construction data lifecycle management method. According to the artificial wetland construction data, a wetland state model is constructed through BIM technology to obtain a three-dimensional state model of the artificial wetland after the construction is completed under the current artificial wetland construction data, and according to the wetland state model, the wetland basic information in the wetland state model is extracted. On the basis of the wetland basic information, combined with the regional information, several purification influencing factors that affect the purification capacity of the artificial wetland are analyzed, and several purification influencing factors are comprehensively analyzed to obtain the purification capacity of the artificial wetland.

[0075] Figure 1 A schematic diagram of an application scenario provided for the present application. During the construction process of an artificial wetland, the method provided by the present application is applied to analyze the artificial wetland construction data and regional information, and the construction adjustment parameters are provided to the construction party so that the construction party can adjust the construction process.

[0076] The method provided in the present application is installed in any server, and the server communicates with the regional remote sensing data platform. The artificial wetland construction data provided by the construction party is obtained through the server, and a wetland state model is constructed through the BIM technology based on the artificial wetland construction data to obtain a three-dimensional state model of the artificial wetland after the construction is completed under the current artificial wetland construction data, and the basic wetland information in the wetland state model is extracted according to the wetland state model. On the basis of the wetland basic information, by combining the regional information provided by the regional remote sensing data platform, several purification influencing factors that affect the purification capacity of the artificial wetland are analyzed, and the purification capacity of the artificial wetland is obtained by comprehensively analyzing several purification influencing factors. When the purification capacity of the artificial wetland cannot meet the purification demand, by analyzing several wetland basic information and regional information, several construction adjustment parameters that need to be adjusted are determined, so that the construction personnel can adjust the construction process according to the precise construction adjustment parameters, so that the purification capacity of the artificial wetland completed according to the adjusted construction process is highly consistent with the purification demand of the surrounding environment, and the management of the artificial wetland construction data is improved to avoid the subsequent high cost of artificial wetland reconstruction.

[0077] For specific implementation methods, please refer to the following embodiments.

[0078] Figure 2 This is a flowchart of a method for managing and controlling the lifecycle of construction data based on BIM provided in one embodiment of the present application. The method of this embodiment can be applied to the server in the above scenario. Figure 2 As shown, the method includes:

[0079] S201. Acquire artificial wetland construction data, and build a wetland status model based on the artificial wetland construction data and BIM technology, analyze the wetland status model, and extract some basic wetland information.

[0080] The artificial wetland construction data can be considered as the relevant parameters generated before and during the construction of the artificial wetland, and the artificial wetland construction data can be provided by the construction party.

[0081] The wetland status model can be considered as a three-dimensional model of an artificial wetland constructed using BIM technology based on artificial construction data.

[0082] Wetland basic information can be considered as the basic information of artificial wetlands that can be directly obtained from the wetland status model, such as the location of the water inlet and the location of the water outlet.

[0083] Specifically, during the construction of artificial wetlands, there are many influencing factors that will affect the ability of the artificial wetlands to purify the surrounding environment after construction is completed. Moreover, if reconstruction is carried out on the basis of the completed artificial wetlands, it is easy to destroy the ecological environmental foundation that has been formed during the construction of the artificial wetlands, resulting in difficulty in forming a stable ecological environment in the artificial wetlands in the future, which in turn has a negative impact on the purification capacity of the artificial wetlands.

[0084] Therefore, using BIM technology, according to the relevant construction data formulated before the start of the construction process and the real-time data generated during the construction process, a wetland status model is constructed to reflect the status of the artificial wetland after the construction is completed under the above-mentioned relevant construction data and real-time data, and provide construction personnel with overall visualization data of the artificial wetland. Then, through BIM tools such as BIMcollab (Building Information Modeling Collaboration) and BIMlink (Building Information Modeling Link), the basic wetland data in the wetland status model can be extracted, providing an important data basis for the subsequent analysis of the ecological status of the artificial wetland after the construction is completed based on the basic wetland data.

[0085] S202: Acquire regional information, analyze some basic information of wetlands based on the regional information, and determine some purification influencing factors.

[0086] Regional information can be considered as relevant information about the area where the artificial wetland construction area is located, such as terrain information and climate information. Regional information can be obtained through the regional remote sensing data platform.

[0087] Purification influencing factors can be considered as specific factors that will affect the purification capacity of the constructed wetland after construction is completed.

[0088] Specifically, the purification capacity of the artificial wetland after the completion of construction is not only affected by the construction plan and a series of data during the construction process, but also by various factors in the area where the artificial wetland is located, such as topography and climate. The topography mainly affects the flow velocity and retention time of water in the artificial wetland, while the climate mainly affects the amount of water in the artificial wetland. On the basis of regional information, some basic wetland information is analyzed through mathematical analysis to obtain the purification influencing factors that affect the purification capacity of the artificial wetland after the completion of construction, which provides important data basis for the subsequent evaluation of the purification capacity of the artificial wetland under the current construction plan.

[0089] S203. Analyze several purification influencing factors, determine the purification capacity of the artificial wetland, and judge whether construction adjustment is needed based on the purification capacity of the artificial wetland.

[0090] The purification capacity of artificial wetlands can be considered as a criterion for measuring the purification effect of artificial wetlands on the surrounding environment, which can be divided into high purification capacity and low purification capacity.

[0091] Specifically, after obtaining several purification influencing factors, the purification speed of the artificial wetland is quantified through a mathematical analysis process. When the purification speed quantification data is maintained within a high level range, it can be considered that the purification capacity of the artificial wetland is at a high level and meets the purification needs of the surrounding environment.

[0092] When the quantified data of the purification speed remains within a low range or fluctuates greatly, it can be considered that the purification capacity of the artificial wetland is at a low level and it is difficult to meet the purification needs of the surrounding environment, which means that the artificial wetland completed in the current construction plan cannot achieve the expected purification target. At this time, it is necessary to adjust the construction process in time to avoid high costs for the subsequent reconstruction of the artificial wetland.

[0093] S204: If construction adjustment is required, analyze some wetland basic information and regional information, and determine some construction adjustment parameters, so that the construction party can adjust the construction process according to the some construction adjustment parameters.

[0094] Construction adjustment parameters can be considered as relevant parameters in the construction process that need to be adjusted to improve the purification capacity of artificial wetlands.

[0095] Specifically, when the purification capacity of the artificial wetland cannot meet the purification demand and construction adjustment is needed, mathematical analysis is used to comprehensively analyze a number of wetland basic information and regional information, quantify the impact of the wetland basic information and regional information on the purification capacity of the artificial wetland, and adjust the construction parameters based on the mathematical analysis results until the purification capacity of the artificial wetland meets the purification demand, so as to obtain a number of construction adjustment parameters, so that construction personnel can adjust the construction process according to the precise construction adjustment parameters, so that the purification capacity of the artificial wetland completed according to the adjusted construction process is highly consistent with the purification needs of the surrounding environment.

[0096] Through the method provided in this embodiment, a wetland state model is constructed according to the artificial wetland construction data through BIM technology to obtain a three-dimensional state model of the artificial wetland after the construction is completed under the current artificial wetland construction data, and the basic information of the wetland in the wetland state model is extracted according to the wetland state model. On the basis of the wetland basic information, combined with the regional information, several purification influencing factors that affect the purification capacity of the artificial wetland are analyzed, and the purification capacity of the artificial wetland is obtained by comprehensive analysis of several purification influencing factors. When the purification capacity of the artificial wetland cannot meet the purification demand, by analyzing several wetland basic information and regional information, several construction adjustment parameters that need to be adjusted are determined, so that the construction personnel can adjust the construction process according to the precise construction adjustment parameters, so that the purification capacity of the artificial wetland completed according to the adjusted construction process is highly consistent with the purification demand of the surrounding environment, and the management of the artificial wetland construction data is improved to avoid the subsequent high cost of artificial wetland reconstruction.

[0097] In some embodiments, based on the wetland state model, the water body area and the soil area are determined; the water body area is analyzed to determine the water inlet position and the water outlet position; based on the water inlet position and the water outlet position, the water body area is analyzed to determine the water body course; the water body area and the soil area are analyzed to determine the transition area; the water body area, the soil area, the water body course and the transition area are used as some basic wetland information.

[0098] The water body area can be considered as the distribution area of ​​water flow in the wetland state model.

[0099] The soil zone can be considered as the distribution area of ​​soil in the wetland state model.

[0100] The water inlet location can be considered as the water inlet location in the wetland state model used to introduce external water flow into the constructed wetland.

[0101] The outlet position can be considered as the water outlet position used to divert water out of the wetland in the wetland state model.

[0102] Water travel distance can be considered as the distance that water flows between the inlet and outlet locations in the wetland state model.

[0103] The transition zone can be considered as the boundary area between water and soil in the wetland state model.

[0104] Specifically, during the planning stage of an artificial wetland, the locations of the inlet and outlet of the artificial wetland are usually set in advance, and the water body is arranged according to the inlet and outlet locations so that the water flow range can cover the soil area in the artificial wetland as much as possible, thereby ensuring the purification effect of the artificial wetland on the water body. At the same time, high-density vegetation is covered in the transition area between the water body and the soil to further enhance the purification effect of the artificial wetland on the water body.

[0105] Therefore, on the basis of the constructed wetland state model, the water area and soil area in the wetland state model are extracted through BIM tools such as BIMcollab and BIMlink. On the basis of the water area, the positions of the water inlet and outlet are determined, and the water flow path in the wetland state model is obtained according to the relative distance between the water inlet and outlet and the water distribution in the water area. At the same time, the boundary area between the water area and the soil area is extracted through the geometric operation in the BIM software to determine the transition area. The water area, soil area, water path and transition area are used as some basic wetland information, so that the factors affecting the purification effect of artificial wetlands obtained later based on some basic wetland information are more representative.

[0106] Through the method provided in this embodiment, on the basis of the wetland state model, the water body area and soil area in the wetland state model are extracted, and the water inlet position and the water outlet position are determined according to the water body area, and then the water body course is obtained. The water body area and the soil area are comprehensively considered to determine the transition area. The water body area, soil area, water body course and transition area are used as some basic wetland information, so that the factors affecting the purification effect of the artificial wetland obtained later based on some basic wetland information are more representative.

[0107] In some embodiments, a preset water body throughput is obtained, and a construction impact factor is determined based on the preset water body throughput, water body travel and terrain information; a regional impact factor is determined based on soil information and climate information; based on the transition zone, the area of ​​the transition zone is obtained; and the construction impact factor, regional impact factor and transition zone area are used as several purification impact factors.

[0108] Regional information includes, but is not limited to, terrain information, soil information, and climate information.

[0109] The preset water throughput can be considered as the amount of water to be processed per unit time preset during the artificial wetland design phase, including but not limited to the preset water inlet and preset water outlet.

[0110] The construction influencing factors can be considered as the quantitative factors that affect the transition area during the construction process.

[0111] The regional impact factor can be considered as a quantitative factor of the impact of regional information on the transition area.

[0112] The area of ​​the transition zone can be considered as the basic area value corresponding to the transition zone in the wetland state model.

[0113] Specifically, since the transition zone is usually the area with the most active biological activities and chemical reactions in artificial wetlands, the purification capacity of artificial wetlands is decisively influenced by the transition zone. By analyzing the purification influencing factors that affect the transition zone, the changes in the transition zone can be used to reflect the purification capacity of the wetland representatively.

[0114] Among them, the preset water body throughput affects the amount of water in the artificial wetland per unit time, and the water volume directly affects the area change of the boundary area between the water body and the soil, namely the transition area. The size of the water body's course directly affects the size of the transition area, and the terrain information in the regional information, such as the terrain slope, directly affects the residence time of the water body in the transition area. The above-mentioned preset water body throughput, water body course and terrain slope can all be adjusted during the construction stage. The influence of the preset water body throughput, water body course and terrain slope on the size of the transition area is quantified through mathematical analysis, and then the construction influencing factors are obtained.

[0115] At the same time, soil information in regional information, such as soil infiltration rate, directly affects the retention time of water in the entire artificial wetland, while climate information, such as precipitation and evaporation, directly affects the variation of water volume in the wetland. In addition, soil infiltration rate and evaporation are also related to the preset vegetation coverage rate in the artificial wetland. The higher the preset vegetation coverage rate, the lower the soil infiltration rate and evaporation rate, the longer the retention time of water in the artificial wetland, and the larger the area of ​​the corresponding transition zone. The above-mentioned soil infiltration rate, preset vegetation coverage rate, precipitation and evaporation are all affected by the region where the artificial wetland is located. The influence of soil infiltration rate, preset vegetation coverage rate, precipitation and evaporation on the size of the transition zone area is quantified through mathematical analysis, thereby determining the regional influencing factors.

[0116] Furthermore, based on the wetland state model, the value of the corresponding transition zone area in the wetland state model is obtained through BIM tools, and the transition zone area, construction influencing factors and regional influencing factors are used as several purification factors. In order to facilitate the subsequent use of the transition zone area, the changes in the actual transition zone area under the influence of the construction process and regional factors are quantified by comprehensively considering the construction influencing factors and regional influencing factors, providing an important data basis for measuring the actual purification capacity of the artificial wetland after the construction is completed.

[0117] Through the method provided in this embodiment, the preset water body throughput, water body travel and terrain information are analyzed to determine the construction impact factors of the construction process on the transition area. At the same time, the soil information and climate information are analyzed to determine the regional impact factors of the area where the artificial wetland is located on the transition area. According to the transition area, the area of ​​the transition area is obtained, and the area of ​​the transition area, the construction impact factors and the regional impact factors are used as several purification factors. In order to facilitate the subsequent changes in the actual transition area area under the influence of the dual factors of the construction process and the region on the basis of the area of ​​the transition area, by comprehensively analyzing the construction impact factors and the regional impact factors, an important data basis is provided for measuring the actual purification capacity of the artificial wetland after the construction is completed.

[0118] In some embodiments, the construction influencing factor is determined based on the preset water body throughput, water body travel and terrain information, referring to formula (1):

[0119] (1)

[0120] in, is the construction influencing factor, To preset the water intake, To preset the water output, For water body travel, is the terrain slope, is the water adjustment coefficient, is the water flow adjustment factor.

[0121] The terrain information includes but is not limited to the terrain slope. The terrain slope can be considered as the slope value corresponding to the terrain of the area between the water inlet and the water outlet in the artificial wetland during the current construction stage.

[0122] The water adjustment coefficient can be considered as the difference between the preset water inlet and the preset water outlet, that is, the influence coefficient of the retained water in the artificial wetland on the size of the transition zone in the artificial wetland. The water adjustment coefficient can be obtained by collecting and analyzing a large number of relevant data from other built artificial wetlands.

[0123] The water flow adjustment coefficient can be considered as the influence coefficient of the water flow velocity in the artificial wetland on the size of the transition zone in the artificial wetland. The water flow adjustment coefficient can be obtained by collecting and analyzing a large number of relevant data from other built artificial wetlands.

[0124] Specifically, formula (1) expresses the effect of the amount of retained water and water flow velocity in the constructed wetland on the area of ​​the transition zone, where the amount of retained water can be regarded as the difference between the inflow and outflow of the constructed wetland, and the water flow velocity is affected by the water body travel and the terrain slope. It expresses the changing characteristics of water flow under the water body with a certain terrain slope. When the terrain slope is larger, the water flow speed is dominated by the terrain slope. When the terrain slope is smaller, the water flow speed is dominated by the water body. Considering that the change range of terrain slope in the construction scene of artificial wetland is not very large, The impact of terrain slope is diluted so that the impact of terrain slope is maintained within a smaller range.

[0125] Through the method provided in this embodiment, through mathematical analysis, a mathematical formula is designed to quantify the impact of preset water body throughput, water body course and terrain information on the area of ​​the transition zone, so as to obtain the construction impact factor, which comprehensively considers the detailed impact of the preset water body throughput, water body course and terrain information on the area of ​​the transition zone, so that the construction impact factor is highly consistent with the actual state of the artificial wetland.

[0126] In some embodiments, the regional impact factor is determined based on soil information and climate information, referring to formula (2):

[0127] (2)

[0128] in, is the regional impact factor, To preset vegetation coverage, is the basic soil permeability, is the precipitation, is the evaporation amount, is the soil adjustment factor, is the intervention water adjustment coefficient, is the vegetation impact weight, is the weight of infiltration impact.

[0129] Soil information includes but is not limited to basic soil permeability and preset vegetation coverage.

[0130] Basic soil permeability can be considered as the infiltration rate of water in a unit area of ​​soil per unit time simply reflected by the influence of soil texture.

[0131] The preset vegetation coverage rate can be considered as the vegetation coverage rate that the artificial wetland needs to achieve after construction, which is set in advance by the construction party.

[0132] The soil adjustment coefficient can be considered as the influence coefficient of the current overall soil infiltration rate on the area of ​​the transition zone. The soil adjustment coefficient can be obtained through soil infiltration experiments.

[0133] The intervention water adjustment coefficient can be considered as the influence coefficient of external intervention water on the area of ​​transition zone. The external intervention water is mainly precipitation, and the intervention water adjustment coefficient can be obtained through simulated precipitation experiments.

[0134] The vegetation impact weight can be considered as the influence weight of vegetation coverage on the overall soil infiltration rate.

[0135] The infiltration impact weight can be considered as the influence weight of the base soil infiltration rate on the overall soil infiltration rate.

[0136] Specifically, the influence of soil and precipitation on the transition zone area in artificial wetlands is expressed by formula (2), where the soil infiltration rate directly affects the retention time of water in the soil, which means that the higher the soil infiltration rate, the larger the transition zone area. In addition to being affected by the texture of the soil itself, the soil infiltration rate is also affected by the vegetation coverage rate on the soil. Specifically, the increase in vegetation coverage rate will promote the increase in soil infiltration rate. Therefore, on the basis of the basic soil infiltration rate of the soil itself, the influence of vegetation coverage rate also needs to be considered. It expresses the influence of the overall soil infiltration rate on the transition area under the combined effect of the basic infiltration rate and the weighted value of vegetation coverage. Expressed at time point Under the condition of precipitation, the difference between precipitation and evaporation, that is, the precipitation in the artificial wetland water body, affects the area of ​​the transition zone.

[0137] Through the method provided in this embodiment, mathematical analysis is performed and a mathematical formula is designed to quantify the impact of soil information and climate information on the area of ​​the transition zone, thereby obtaining a regional impact factor, which comprehensively considers the detailed impact of preset vegetation coverage, basic soil permeability, precipitation and evaporation on the area of ​​the transition zone, so that the regional impact factor is highly consistent with the actual state of the artificial wetland.

[0138] In some embodiments, based on the area of ​​the transition zone, the transition zone area change information is determined according to the construction influencing factors and the regional influencing factors; based on the transition zone area change information, the water body residence time change information is determined; based on the transition zone area change information and the water body residence time change information, the artificial wetland purification capacity is determined.

[0139] The area change information of the transition zone can be considered as the area information of the transition zone in the artificial wetland at different time nodes.

[0140] The water retention time variation information can be considered as the retention time information of water bodies in artificial wetlands at different time nodes.

[0141] Specifically, since the area of ​​the transition zone in the artificial wetland will fluctuate in the actual scenario, and through the analysis of the above-mentioned embodiments, it can be seen that the area change of the transition zone is affected by the combined effect of construction influencing factors and regional influencing factors, based on the area of ​​the transition zone in the wetland state model, mathematical analysis is performed to comprehensively consider the construction influencing factors and regional influencing factors to obtain the area change information of the transition zone.

[0142] On the basis of the information of transition zone area change, since the change of transition zone area will directly affect the retention time of water in the artificial wetland, specifically, the larger the transition zone area, the longer the retention time of water in the artificial wetland, and the retention time of water in the artificial wetland will affect the purification capacity of the artificial wetland, specifically, when the water retention time is too short, the artificial wetland does not have enough time to treat the pollutants in the water, and the purification effect is poor; when the water retention time is too long, the water is prone to eutrophication, causing the breeding of microorganisms in the water and aggravating water pollution. Through mathematical analysis, according to the information of transition zone area change, the water retention time change information is obtained, and according to the information of transition zone area change and water retention time change information, the purification capacity of the artificial wetland is quantified through mathematical analysis to accurately determine the purification capacity of the artificial wetland.

[0143] Through the method provided in this embodiment, based on the area of ​​the transition zone in the wetland state model, the construction influencing factors and the regional influencing factors are comprehensively analyzed to determine the change information of the transition zone area under the influence of the construction influencing factors and the regional influencing factors, and based on the change information of the transition zone area, the change information of the water body residence time is determined. By comprehensively combining the change information of the transition zone area and the change information of the water body residence time, the purification capacity of the artificial wetland is determined, making the consideration of the purification capacity of the artificial wetland more comprehensive and representative.

[0144] In some embodiments, based on the area of ​​the transition area, according to the construction impact factor and the regional impact factor, the transition area area change information is determined, referring to formula (3):

[0145] (3)

[0146] in, is the area change information of the transition region, is the transition region area, is the construction influencing factor, is the regional impact factor;

[0147] According to the change information of the transition area area, the change information of the water body residence time is determined, referring to formula (4):

[0148] (4)

[0149] in, is the water retention time change information, is the area change information of the transition region, is the coefficient of variation.

[0150] The coefficient of variation can be considered as the relationship coefficient between the change in transition zone area and the change in water retention time. The coefficient of variation can be obtained by analyzing the relationship data between the transition zone area and water retention time in a large number of artificial wetlands.

[0151] Specifically, the area change information of the transition area at different time nodes expressed by formula (3) based on the area of ​​the transition area in the wetland state model, when the transition area is affected by the construction impact factor and the regional impact factor, accurately reflects the relationship between the construction impact factor, the regional impact factor and the transition area.

[0152] Furthermore, after obtaining the transition zone area change information, since there is a linear relationship between the transition zone area and the water body retention time, the linear function in formula (4) is used to express the direct relationship between the transition zone area and the water body retention time to obtain the water body retention time change information.

[0153] Through the method provided in this embodiment, based on the area of ​​the transition zone, construction influencing factors and regional influencing factors, a mathematical formula is designed to quantify the transition zone change information, and based on the transition zone area change information, a mathematical formula is designed to express the relationship between the transition zone area and the water body retention time, and the water body retention time change information is quantified, thereby providing an accurate data basis for the subsequent evaluation of the artificial wetland purification capacity based on the transition zone area change information and the water body retention time change information.

[0154] In some embodiments, according to the transition area area change information and the water retention time change information, the wetland inlet pollution concentration is set and the wetland outlet pollution concentration change information is determined, referring to formula (5):

[0155] (5)

[0156] in, Information on changes in wetland effluent pollution concentrations, is the pollution concentration entering the wetland water, is the area change information of the transition region, is the water retention time change information, is the purification rate constant, is the transition area impact index, is the residence time impact index;

[0157] According to the change information of wetland outflow pollution concentration and wetland inflow pollution concentration, the purification rate change information is determined by formula (6):

[0158] (6)

[0159] in, To purify the rate change information, Information on changes in wetland effluent pollution concentrations, is the pollution concentration of water entering the wetland; the purification capacity of the artificial wetland is determined based on the purification rate change information.

[0160] The pollution concentration of wetland water inflow can be considered as the water pollution concentration at the water inlet of the artificial wetland.

[0161] The information on changes in wetland effluent pollution concentration can be considered as the information on changes in pollution concentration of the effluent water at the artificial wetland outlet over time.

[0162] The purification rate constant can be considered as the degradation rate of pollutants in water by artificial wetlands under ideal conditions.

[0163] The transition area impact index can be considered as the impact index of the transition area on the water pollution concentration. The transition area impact index can be obtained by analyzing the relevant data in the built artificial wetlands.

[0164] The residence time impact index can be considered as the influence index of water residence time on water pollution concentration. The residence time impact index can be obtained by analyzing relevant data in the built artificial wetlands.

[0165] The purification rate change information can be considered as the information on the change of purification speed over time in the artificial wetland.

[0166] Specifically, from the analysis of the aforementioned embodiments, it can be seen that the area of ​​the transition zone is linearly related to the water retention time. When the water retention time is too short, the artificial wetland does not have enough time to treat the pollutants in the water body, and the purification effect is poor. When the water retention time is too long, the water body is prone to eutrophication, causing the water body to breed microorganisms and aggravate water pollution. From the above analysis, it can be seen that there is a nonlinear relationship between the water retention time and the purification capacity of the artificial wetland, so the purification capacity of the artificial wetland is also nonlinearly related to the area of ​​the transition zone. In summary, it can be concluded that there is a nonlinear relationship between the area of ​​the transition zone, the water retention time and the water pollution concentration.

[0167] Therefore, through the nonlinear exponential function in formula (5) On the basis of the pollution concentration of wetland inflow, the nonlinear relationship between the transition zone area, water retention time and water pollution concentration in the artificial wetland is comprehensively considered to determine the change information of wetland outflow pollution concentration reflecting the change of water pollution concentration at the water outlet over time.

[0168] Furthermore, after obtaining the information on the change of pollutant concentration in wetland effluent, the formula (6) is used to calculate The ratio between the pollution concentration of wetland effluent and the pollution concentration of wetland influent at different time points is measured. The larger the ratio, the closer the pollution concentration of wetland effluent is to the pollution concentration of wetland influent, which means that the purification capacity of artificial wetlands is worse, and vice versa, it means that the purification capacity of artificial wetlands is stronger. The final purification rate value is normalized. The closer the purification rate value is to 1, the stronger the purification capacity of the artificial wetland at the current time point is.

[0169] If the purification rate at different time points in the purification rate change information is always maintained close to 1, it means that the overall purification capacity of the artificial wetland is at a high level. Conversely, if the purification rate at different time points in the purification rate change information is always maintained far away from 1, or the purification rate at different time points in the purification rate change information fluctuates greatly, it means that the overall purification capacity of the artificial wetland is at a low level.

[0170] Through the method provided in this embodiment, the nonlinear relationship between the transition zone area, the water retention time and the water pollution concentration in the artificial wetland is comprehensively considered, and the wetland effluent pollution concentration change information reflecting the change of the water pollution concentration at the water outlet over time is determined through a mathematical formula. Then, based on the wetland effluent pollution concentration change information, the purification rate change information is determined through a mathematical formula. The purification capacity of the artificial wetland is measured by the purification rate change information. The purification capacity of the artificial wetland is measured by precise mathematical quantitative data, so that the artificial wetland purification capacity is highly consistent with the actual situation of the artificial wetland.

[0171] In some embodiments, the average effluent pollution concentration is determined according to the wetland effluent pollution concentration change information; based on the average effluent pollution concentration, the preset water body throughput, the water body travel, the terrain slope and the preset vegetation coverage rate, refer to formula (7) to determine the effluent pollution gradient:

[0172] (7)

[0173] in, is the effluent pollution gradient, is the average effluent pollution concentration, To preset the water intake, To preset the water output, For water body travel, is the terrain slope, The vegetation coverage rate is preset; according to the outlet water pollution gradient, a number of update parameter values ​​are obtained; based on the number of update parameter values, the adjustment purification rate change information is determined; the adjustment purification rate change information is analyzed, and according to the analysis results, it is determined whether to use the number of update parameter values ​​as a number of construction adjustment parameters.

[0174] The average effluent pollution concentration can be considered as the average value of the wetland effluent pollution concentration corresponding to all time nodes in the wetland effluent pollution concentration change information.

[0175] The effluent pollution gradient can be considered as the degree of influence or sensitivity of changes in different parameters on changes in effluent pollution concentration.

[0176] Updating parameter values ​​can be considered as adjusting relevant parameters to obtain specific values ​​of the adjusted parameters.

[0177] The adjusted purification rate change information may be considered as the purification rate value change information obtained after adjusting the relevant parameters.

[0178] Specifically, among some basic wetland information and regional information, the basic soil infiltration rate, precipitation and evaporation are affected by soil texture and natural climate and cannot be adjusted by human intervention. Therefore, when the purification capacity of artificial wetlands cannot meet the purification needs, the preset water throughput, water course, terrain slope and preset vegetation coverage rate that can be adjusted by human intervention during the construction phase can be substituted into formula (7) to obtain the corresponding effluent pollution gradient when the above series of parameters change, so as to accurately reflect the relationship between the above series of parameter changes and effluent pollution changes through mathematical expressions.

[0179] After obtaining the water pollution gradient, a number of updated parameter values ​​corresponding to the above series of parameters are obtained through mathematical analysis based on the water pollution gradient, and the several updated parameter values ​​are substituted into a series of formulas of the aforementioned embodiment to obtain the adjusted purification rate change information, and the adjusted purification rate change information is analyzed. If the purification rate value in the adjusted purification rate change information is maintained at a state close to 1, it means that the above adjustment can meet the purification requirements, and the several updated parameter values ​​will be used as several construction adjustment parameters.

[0180] If the purification rate value in the adjusted purification rate change information still remains far away from 1 or fluctuates greatly, the average effluent pollution concentration is obtained based on the adjusted purification rate change information, and the average effluent pollution concentration and several updated parameter values ​​are substituted into formula (7) to obtain a new effluent pollution concentration. Based on the new effluent pollution concentration, several new updated parameter values ​​are obtained, and based on the new updated parameter values, it is re-judged whether the adjusted purification rate change information meets the purification demand.

[0181] Repeat the above steps until the purification rate change information meets the purification requirements, and use the corresponding updated parameter values ​​as construction adjustment parameters.

[0182] Through the method provided in this embodiment, on the basis of the average effluent pollution concentration, according to the preset water body throughput, water body travel, terrain slope and preset vegetation coverage, a mathematical formula is used to obtain an effluent pollution gradient that reflects the degree to which the water body pollution concentration at the artificial wetland outlet is affected by the above-mentioned series of parameters, and according to the effluent pollution gradient, a number of updated parameter values ​​are obtained, and based on the corresponding adjusted purification rate change information under the several updated parameter values, it is determined whether to use the several updated parameter values ​​as the several construction adjustment parameters, so as to comprehensively quantify the impact of each parameter on the effluent pollution, so that the subsequent updated parameter values ​​obtained according to the effluent pollution gradient are more accurate.

[0183] In some embodiments, the preset water body throughput, water body travel, terrain slope and preset vegetation coverage are used as parameters and substituted into formula (8) to obtain several updated parameter values;

[0184] (8)

[0185] in, is the current updated parameter value, is the current substitution parameter, is the preset update step size, is the effluent pollution gradient.

[0186] The preset update step size can be considered as the interval step size of parameter update, which is used to ensure the convergence speed and stability of the formula. The preset update step size can be set according to the parameter conditions.

[0187] Specifically, based on the outlet water pollution gradient, the updated parameter values ​​corresponding to each parameter in the preset water body throughput, water body travel, terrain slope and preset vegetation coverage are calculated by formula (8) to accurately obtain the corresponding values ​​that need to be updated for each parameter under the current outlet water pollution gradient, so as to provide accurate data basis for construction personnel to adjust the construction process according to the construction adjustment parameters.

[0188] Through the method provided in this embodiment, a mathematical formula is designed to calculate the updated parameter values ​​corresponding to each parameter in the preset water body throughput, water body travel, terrain slope and preset vegetation coverage rate according to the outlet water pollution gradient, so as to accurately obtain the corresponding numerical value that needs to be updated for each parameter, thereby providing accurate data basis for the construction party to subsequently adjust the construction process according to the construction adjustment parameters.
