On the other hand, there is a lack of scientific and systematic evaluation methods in the selection of landscaping methods, and they often only consider aesthetics, ignoring ecological rationality and functional adaptability, and are unable to fully realize the ecological benefits and use value of the garden.

[0010] At the same time, the functional adaptation value and ecological rationality value are transmitted to the adaptive analysis and processing module;

[0011] The adaptive analysis and processing module comprehensively calculates the functional adaptation value and the ecological rationality value to obtain the matching value, and determines the pre-selected landscaping method according to the size of the matching value. At the same time, it analyzes the existing pre-selected landscaping methods, selects the one with the largest matching value among the same pre-selected landscaping methods as the standard, generates design information, and transmits it to the landscape design information output module.

[0015] As a further solution of the present invention, the garden area analysis module divides the target garden into functional areas according to the spatial layout in the following specific manner:

[0016] According to the spatial layout corresponding to the target garden, it is divided into multiple functional areas, and the label is recorded as i, and i = 1, 2, ..., j, where j represents the number of functional areas, and the spatial layout represents the topography, distribution of landscape elements and expected use functions;

[0022] The obtained ecological diversity value and functional ornamental value are comprehensively calculated, and the functional adaptability value is calculated according to the formula: functional adaptability value = ecological diversity value × ecological diversity weight + functional ornamental value × functional ornamental weight. The specific values ​​of the ecological diversity weight and functional ornamental weight are set by the operator.

[0023] As a further solution of the present invention, the garden area analysis module obtains the vegetation diversity value and the ecological utilization value in the following specific manner:

BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Figure 1 This is a block diagram of the system principle of the present invention. DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] For example 1, please refer to Figure 1This application provides a garden design and landscaping auxiliary system based on BIM technology, including a garden information acquisition module, a garden area analysis module, an adaptive analysis and processing module, and a landscaping design information output module. Figure 1 It can be known that the corresponding functional modules are electrically connected in a unidirectional manner.

[0040] The garden information acquisition module is used to acquire the garden information of the target garden. Specifically, the target garden is represented by the garden that needs to be designed and landscaped. It is set by the operator and output to the system. The garden information is directly obtained through the corresponding BIM technology. The garden information is mainly terrain data, specifically the slope and height difference data corresponding to the garden. The acquired garden information is then transmitted to the garden area analysis module.

[0041] The garden area analysis module is used to divide the target garden into regions based on the garden information. When dividing the regions, the region is divided according to the spatial layout of the target garden, and multiple functional regions are obtained. The functional regions are labeled as i, and i=1, 2, ..., j, where j represents the number of functional regions. Then, one group of functional regions is analyzed;

[0042] The regional information of the analysis object and all landscaping methods are obtained at the same time. The landscaping method here represents the artificial layout design based on the regional characteristics and is labeled as a, and a=1, 2, ..., b, where b represents the number of landscaping methods. Then, the matching value of the analysis object and the landscaping method is calculated from the two aspects of functional adaptability and ecological rationality. The analysis here is based on the design requirements corresponding to different landscaping methods.

[0043] The specific method of analyzing functional adaptability is: by evaluating and scoring the ecological diversity and functional ornamental value respectively, the ecological diversity value and functional ornamental value are obtained;

[0044] The specific method of evaluating and scoring ecological diversity is to obtain the number of plant species in the analysis object, quantify the number of plant species, and determine the scoring range. The scoring range here can be set to 0-10 points. Then, the scores are scored based on the plant species, and the scores are recorded as the assigned values ​​to obtain the ecological diversity value. For example, when the number of plant species is 10 or less, the corresponding score is 1 point; 11-20 species correspond to 5 points; 21-30 species correspond to 7 points; 31 species and above correspond to 10 points. If there are 26 plant species in the analysis object, the corresponding assigned value is 7.

[0045] The specific method of evaluating and scoring the functional appreciation is to obtain the types and quantities of all landscape elements in the analysis object, and perform corresponding scoring processing based on the types of landscape elements. At the same time, the corresponding scores are obtained and recorded as values ​​to obtain the corresponding functional appreciation value. For example, when the types of landscape elements are 5 or less, the corresponding score is 1 point. This range indicates that the landscape elements are relatively simple and the functional appreciation is low; 6-10 types correspond to 5 points. This range indicates that the landscape elements have a certain richness and can provide a certain degree of viewing experience and function; 11-15 types correspond to 7 points, indicating that the landscape elements are rich and can better meet the viewing and functional needs; 16 or more types correspond to 10 points, which means that the landscape elements are extremely rich and the functional appreciation is extremely high.

[0046] The obtained ecological diversity value and functional ornamental value are comprehensively calculated. The functional adaptability value is calculated according to the formula functional adaptability value = ecological diversity value × ecological diversity weight + functional ornamental value × functional ornamental weight. The specific values ​​of ecological diversity weight and functional ornamental weight are set by the operator.

[0047] The specific method of analyzing ecological rationality is to evaluate and score vegetation diversity and ecological utilization, and obtain vegetation diversity value and ecological utilization value;

[0048] The specific method of evaluating and scoring vegetation diversity is to obtain the matching vegetation species corresponding to the analysis object, and the matching vegetation species here represent the species of local plants used in the landscaping in large quantities, and at the same time calculate the corresponding quantity proportion of the matching vegetation species, and perform corresponding evaluation and scoring based on the quantity proportion. The obtained score is used as the assignment to obtain the vegetation diversity value, which is as follows: if the proportion is 30% or less, the score is 1 point, indicating that the proportion of local plants is low and the vegetation diversity is poor; if the proportion is 31%-50%, the score is 3 points, which means that the vegetation diversity is at a medium level; if the proportion is 51%-70%, the score is 7 points, indicating that the proportion of local plants is high and the vegetation diversity is good; if the proportion is 71% or more, the score is 10 points, indicating that the vegetation diversity is very good;

[0049] The specific way to evaluate and score the ecological utilization value is to analyze the carbon sequestration capacity corresponding to the analysis object and calculate the corresponding carbon sequestration amount. The carbon sequestration amount here can be calculated by the aboveground biomass method. Specifically, the carbon sequestration capacity is estimated by measuring the biomass of the aboveground part of the grassland, because the carbon storage of grassland is mainly concentrated in the aboveground part. Generally speaking, the carbon content of the aboveground biomass of grassland is about 40%-45%. Assuming that in a 1 square meter sample plot, the dried aboveground biomass is 200 grams, and calculated based on a carbon content of 42%, the carbon storage of 1 square meter of grassland is 84 grams. If the total area of ​​grassland is 500 hectares (5,000,000 square meters), the total carbon sequestration of the grassland is 420 tons. At the same time, the obtained carbon sequestration amount is evaluated and scored, and the obtained score is recorded as the assigned value to obtain the ecological utilization value. When the carbon sequestration amount is lower than 40% of the regional average level, it indicates that the carbon sequestration capacity of the ecosystem is poor, and the corresponding assignment is 1 point. If the carbon sequestration amount is in the regional average level, it indicates that the carbon sequestration capacity of the ecosystem is poor, and the corresponding assignment is 1 point. If the carbon sequestration amount is between 40% and 70% of the regional average, it indicates that the carbon sequestration capacity is at an average level, corresponding to 3 points. If the carbon sequestration amount is between 70% and 100% of the regional average, it indicates that the ecosystem carbon sequestration is in good condition, corresponding to 5 points. When the carbon sequestration amount is between 100% and 150% of the regional average, it indicates that the ecosystem carbon sequestration capacity is excellent, corresponding to 7 points. If the carbon sequestration amount reaches or exceeds 150% of the regional average, it indicates that the ecosystem has excellent carbon sequestration performance, corresponding to 10 points.

[0050] The obtained vegetation diversity value and ecological utilization value are comprehensively calculated according to the formula: ecological reasonable value = vegetation diversity value × vegetation diversity weight + ecological utilization value × ecological utilization weight, to obtain the ecological reasonable value. The specific values ​​of vegetation diversity weight and ecological utilization weight are set by the operator.

[0051] The obtained functional fitness value and ecological rationality value are transmitted to the adaptive analysis and processing module.

[0052] Adaptive analysis and processing module, which is used to calculate the matching value between the analysis object and the landscaping method based on the obtained functional fitness value and ecological rationality value. The matching value corresponding to the analysis object is calculated according to the formula matching value = functional fitness value × y1 + ecological rationality value × y2, where y1 and y2 are corresponding weight coefficients. The specific values ​​are set by the operator. Similarly, the matching value corresponding to the analysis object and all landscaping methods n is calculated and recorded as Pa. At the same time, all functional areas i are processed in the same way and the corresponding matching values ​​are calculated. At the same time, they are sorted from large to small according to the matching value Pa, and the landscaping method with the largest matching value is selected as the pre-selected method;

[0053] Obtain the pre-selected landscaping methods corresponding to all functional areas, determine whether there are identical pre-selected landscaping methods, and if so, generate identical analysis signals; otherwise, generate corresponding design information based on the generated pre-selected landscaping methods as a standard, and transmit the design information to the landscaping design information output module;

[0054] Then, the obtained identical analysis signals are processed to obtain the functional areas corresponding to the same pre-selected landscaping methods and recorded as the areas to be analyzed. Then, the matching values ​​of the areas to be analyzed and the pre-selected landscaping methods are obtained, and the matching values ​​are compared. The area to be analyzed with the largest matching value is used as the standard to obtain the standard area. The corresponding pre-selected landscaping methods are matched with the standard area to generate design information. At the same time, the design information is transmitted to the landscaping design information output module, and the remaining areas to be analyzed are further analyzed.

[0055] Obtain the landscaping methods corresponding to the area to be analyzed, which is the remaining area to be analyzed. Select the largest matching value among the remaining landscaping methods and use the landscaping method corresponding to the largest matching value as the standard to generate design information. This design information is then transmitted to the landscaping design information output module. If the same situation persists, filter based on the matching value, and repeat the same process.

[0056] The landscape design information output module is used to display the generated design information to the corresponding operator.

[0057] Example 2: This example is implemented on the basis of Example 1, and differs from Example 1 in the following aspects:

[0058] When calculating the carbon sink, this application adopts the carbon storage assessment method for analysis. Specifically, the carbon storage of wetland plants and soil is measured separately to calculate the total carbon sink capacity. For wetland plants, the plant biomass is measured using a method similar to the forest biomass method or the grassland biomass method, and then the plant carbon storage is calculated based on the plant carbon content. For wetland soil, soil samples of different depths are collected, the soil organic carbon content is measured, and the soil carbon storage is obtained by multiplying it by the soil volume. Finally, the plant carbon storage and soil carbon storage are added together to obtain the total carbon sink of the wetland. For example, the carbon storage of a wetland plant is 50 tons / hectare, the soil organic carbon content is 2%, the soil bulk density is 1.2 grams / cubic centimeter, the average depth is 1 meter, and the soil carbon storage is calculated to be 240 tons / hectare. The total carbon sink of the wetland is 290 tons / hectare.

[0059] Embodiment 3: This embodiment is based on Embodiment 1 and differs from Embodiment 1 and Embodiment 2 in the following aspects:

[0060] When calculating the carbon sink itself, the biomass method is used for analysis and calculation. Specifically, the biomass of various parts of the forest, such as trees, shrubs, and herbs, is measured, and then the carbon sequestration capacity of the forest is calculated based on the conversion relationship between biomass and carbon storage. First, the diameter at breast height and tree height of different tree species in the forest are measured using the standard wood method, sample plot method, etc., and the biomass of individual trees is calculated using the biomass equation, and then the stand biomass is summarized. Then, based on the average conversion coefficient of forest biomass and carbon content (generally 0.45-0.5), the biomass is converted into carbon storage. Finally, the carbon sink per unit area is calculated based on the forest area. Assuming that a forest area is 100 hectares, the total biomass is measured and calculated to be 5,000 tons. According to the conversion coefficient of 0.48, the carbon storage is 2,400 tons, and the carbon sink per unit area is 24 tons / hectare.

[0061] The fourth embodiment, as the fourth embodiment of the present invention, focuses on combining the implementation processes of the first embodiment, the second embodiment and the third embodiment.

[0062] Some of the data in the above formulas are calculated based on their numerical values ​​and are not substituted into parameter units for calculation. At the same time, the contents not described in detail in this specification belong to the existing technology known to those skilled in the art.

[0063] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
