Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of green ecological restoration, in particular to a method and system for ecological restoration of a power transmission and transformation project in a rocky mountain area based on the growth trend of grass seeds. BACKGROUND

[0002] With the rapid development of economy and the continuous growth of energy demand, as a key infrastructure for power transmission, the construction scale and scope of power transmission and transformation projects are also continuously expanding. Due to its special geographical location and topographical conditions, the rocky mountain area has become one of the important regions for the construction of power transmission and transformation projects. When constructing a power transmission and transformation project in a rocky mountain area, a large amount of earthwork excavation, tower foundation construction, and power transmission line laying are usually required. These engineering activities inevitably cause serious negative impacts on the local ecological environment. Moreover, the complex topography and large terrain undulations in the rocky mountain area make the construction difficult, which increases the risk of ecological environment damage during the construction process. Due to the use and transportation of large construction equipment, geological disasters such as landslides and collapses are easily caused during the construction process, further damaging the ecological environment. At the same time, the activities of construction personnel may also disturb the habitats of wild animals, affecting the survival and reproduction of wild animals. The ecological environment in the rocky mountain area is relatively fragile, and once damaged, it is extremely difficult to recover, requiring a large amount of time, manpower, and resources. Land destruction and vegetation damage will exacerbate soil erosion problems, with a large amount of soil being washed away by rainwater, not only reducing soil fertility and affecting the growth and recovery of vegetation, but also possibly causing the siltation of rivers, lakes, and other water bodies, affecting the rational use of water resources and ecological balance.

[0020] Embodiment 1: the present embodiment provides a kind of ecological restoration method of rocky mountainous area transmission and transformation project based on grass species growth trend, as shown in Figure 1 It includes: Step 1: On-site environmental sampling of the construction area, deriving several on-site environmental characteristics of the construction area, determining the corresponding sub-comprehensive on-site environmental characteristics of each sub-area in the construction area; Step 2: According to the on-site environmental characteristics, screening the grass seeds in the grass seed library to obtain several suitable grass seeds, and according to the growth trend of each suitable grass seed, deriving the optimal survival rate of each suitable grass seed in different sub-areas; Step 3: Matching the optimal suitable grass seed for each sub-area respectively, and constructing and displaying the soil improvement scheme for the corresponding sub-area according to the corresponding sub-comprehensive on-site environmental characteristics; Step 4: After the construction area is completed, generating and displaying the grass seed-soil repair scheme for each sub-area according to the corresponding vegetation growth status of each sub-area.

[0021] In this example, the on-site environmental characteristics represent the soil, water, climate and pollution characteristics of the construction area; In this example, the sub-comprehensive on-site environmental characteristics represent the comprehensive results of all environmental characteristics in a sub-area; In this example, the grass seed library represents a database that collects several grass seeds and their attributes, and the grass seed library is connected with big data for periodic updating; In this example, the optimal survival rate represents the maximum probability of survival of suitable grass seeds in a sub-area; In this example, the soil improvement scheme includes soil improvement before planting and fertilization and moisture retention after planting; In this example, the vegetation growth status represents the growth of grass seeds in the sub-area; In this example, the grass seed-soil repair scheme includes the cultivation of grass seeds and the recovery of soil.

[0022] The working principle and beneficial effects of the above technical solution are as follows: in order to accurately plan and dynamically repair by region, bring significant beneficial effects from the dimensions of ecological restoration efficiency, adaptability and sustainability, first, the sub-comprehensive field environment characteristics of the sub-region are deduced through field sampling, and the differences of different sub-regions in rocky mountainous areas are targeted, then the optimal survival rate is deduced combined with the growth trend of suitable grass species, not only according to the basic screening, the grass species with fast growth, developed root system and strong stress resistance in the specific sub-region can be preferentially selected, further, the soil improvement scheme is constructed according to the sub-comprehensive field environment characteristics, the soil conditions are optimized before planting grass species, avoiding the phenomenon that grass species do not survive due to poor soil foundation, finally, the long-term soil improvement scheme is constructed, which can timely respond to the problems after planting, through dynamically adjusting the soil repair measures to ensure the continuous growth of vegetation, avoiding the ecological restoration halfway, in this way, from environmental sampling, grass species screening to scheme formulation and dynamic adjustment, a standardized process is formed, each step has a clear basis, which is convenient for supervision parties to track the repair progress and quality, ensures that the ecological restoration work is implemented according to the plan, and avoids formal repair.

[0023] In the embodiment 2, on the basis of the embodiment 1, the method for ecological restoration of rocky mountainous power transmission and transformation project based on the growth trend of grass species, the step 1 comprises: Step 11: acquiring the construction process data of the power transmission and transformation project, constructing the virtual construction process of the construction area, deducing the estimated soil hazards generated by the power transmission and transformation project on the construction area, and determining the field damage range corresponding to each estimated soil hazard; Step 12: field soil sampling is performed on each field damage range respectively, and the field soil hazards present in each field damage range are analyzed according to the sampling samples, when the field soil hazards do not match the corresponding estimated soil hazards, the corresponding field damage range is re-sampled; Step 13: analyzing the hazard spreading trend of each construction area according to the field soil hazards combined with the topographic features and climate characteristics of the construction area, generating a plurality of field environment characteristics of the construction area, and identifying the field damage situation of each field environment characteristic to different field damage ranges; Step 14: the field damage situations corresponding to the field damage ranges with adjacent relationship are fused in the same category, the construction area is divided into a plurality of sub-regions according to the fusion results, and the sub-comprehensive field environment characteristics corresponding to each sub-region are constructed according to the corresponding field damage situation.

[0024] In this example, the estimated soil hazard means that the hazards generated by the power transmission and transformation project on the soil in the construction area are analyzed by estimation; In this example, the field hazard range indicates the area in the construction area that is subject to the same type of estimated soil hazard; In this example, the field soil hazard and the estimated soil hazard are not matched, indicating that the previous sampling and estimation work has a large error; In this example, the hazard spread trend indicates the characteristics of a field soil hazard spreading in the construction area; In this example, the same type of fusion refers to the process of considering adjacent field hazard ranges that belong to the same type of field hazard as a larger range.

[0025] The working principle and beneficial effects of the above technical solutions are as follows: first, a virtual construction process is constructed through construction process data, and the possible estimated soil hazards of the power transmission and transformation project are deduced in advance, and the hazard range is determined to avoid missing potential hazards that may be ignored by relying solely on field sampling. Then, the actual hazards are analyzed through field soil sampling, and compared with the estimated hazards. If they are not matched, resampling is needed to correct the bias of virtual deduction in a timely manner, ensuring that all existing soil hazards are identified. Further, the soil hazard, terrain characteristics, and climate characteristics are combined to analyze the hazard spread trend, so that the follow-up repair scheme not only targets the current hazards, but also takes measures to block the spread in advance to avoid further expansion of ecological problems. Finally, adjacent areas with the same type of hazard are fused and divided into sub-regions to ensure that the ecological problems of each sub-region are uniform. The matching grass species and soil improvement scheme can accurately adapt to the core problems of the region, avoiding the problem of uneven repair effect caused by a unified scheme for areas with large differences.

[0026] Embodiment 3: Based on Embodiment 2, the stone mountain power transmission and transformation project ecological restoration method based on grass growth trend further comprises: Compare the corresponding estimated soil hazards and field soil hazards of each field hazard range to obtain the estimation efficiency of each field hazard range; Screen the abnormal field hazard range with an estimation efficiency lower than the specified efficiency, and deduce the estimated existing soil hazards of the construction area according to the virtual construction process; Position the abnormal field hazard range in the construction area, and resample the field environment of the abnormal field hazard range according to the estimated existing soil hazards.

[0027] In this example, the specified efficiency is 80%.

[0028] The working principle and beneficial effects of the above technical solutions are as follows: when the difference between the soil hazard evaluation results of the construction area according to the construction situation and the actual sampling results is too large, it is necessary to resample and analyze the construction area in order to provide effective reference for subsequent work.

[0029] In the embodiment 4, on the basis of the embodiment 1, the method for ecological restoration of the power transmission project in the rocky mountain area based on the growth trend of the grass seeds comprises the following steps. Step 21: screening a plurality of suitable grass seeds from a grass seed library according to the field environment characteristics, and obtaining the corresponding grass seed attributes of each suitable grass seed, and constructing an experimental area environment corresponding to the sub-region according to each sub-comprehensive field environment characteristic; Step 22: planting each suitable grass seed in the experimental area environment, respectively, obtaining the stage growth of each suitable grass seed in different experimental area environments in different cultivation periods, and analyzing the corresponding growth trend of each suitable grass seed in different sub-regions; Step 23: analyzing the first vegetation restoration time of each suitable grass seed in different sub-regions according to the growth trend, and analyzing the growth promotion characteristics and growth inhibition characteristics between different suitable grass seeds, and deducing the corresponding second vegetation restoration time of different suitable grass seeds in different sub-regions when mixed; Step 24: when the first vegetation restoration time is greater than the second vegetation restoration time, setting a mixed label for the corresponding sub-region, otherwise setting a single label, and determining the optimal survival rate of each suitable grass seed in different sub-regions according to the first vegetation restoration time / second vegetation restoration time combined with the corresponding growth trend of the suitable grass seed in different sub-regions.

[0030] In this example, the grass seed attribute represents the attribute of the suitable grass seed itself, including: suitable environment, plant appearance, etc. In this example, the experimental area environment represents a virtual scene constructed in a virtual space to present the environmental characteristics of the sub-region; In this example, the stage growth represents the growth of the suitable grass seed in different cultivation periods; In this example, the first vegetation restoration time represents the time required for the sub-region to achieve full vegetation restoration when only one suitable grass seed is planted in the sub-region, and the second vegetation restoration time represents the time required for the sub-region to achieve full vegetation restoration when two or more suitable grass seeds are planted in the sub-region.

[0031] The working principle and beneficial effects of the above technical solution are as follows: in order to quickly and stably restore vegetation, fix the soil in the construction area in time, reduce the erosion of water and soil loss to the power transmission line foundation, avoid disasters such as landslides caused by long-term exposure of vegetation, realize the cooperation of engineering safe operation and ecological protection, first, the experimental area environment is constructed according to the comprehensive field environment characteristics of the sub-regions, the actual conditions of different sub-regions in the rocky mountainous area are accurately restored, and the incompatibility of water and soil caused by screening grass seeds only through theoretical data is avoided, then the screening process not only refers to the basic attributes of the grass seeds, but also tracks the growth conditions of different cultivation periods, analyzes the growth trend, ensures that the selected suitable grass seeds can adapt to the sub-regional environment for a long time, rather than just survive for a short time, further analyzes the growth promotion or inhibition characteristics between the grass seeds, determines whether the sub-regions need to be mixed or single by comparing the first and second vegetation restoration time, avoids the blind mixing or single planting of the construction area, ensures that each planting mode can promote the restoration with the optimal efficiency, reduces the waste of grass seeds, manpower and other resources, and finally selects the optimal survival rate of each suitable grass seed in different sub-regions, so that the subsequent work is more targeted, and the cost of scheme adjustment caused by fuzzy data is reduced.

[0032] In the embodiment 1, the step 3 comprises: Step 31: according to the planting label corresponding to each sub-region, the sub-region is divided into a single sub-region and a mixed sub-region, and according to the optimal survival rate of each suitable grass seed in different sub-regions, an optimal suitable grass seed corresponding to each sub-region is constructed; Step 32: screening the heavy pollution sub-region with the selected number of optimal suitable grass seeds less than the specified number, constructing a corresponding sub-region model according to the heavy pollution sub-comprehensive field environment characteristics corresponding to the heavy pollution sub-region, and when the heavy pollution sub-region belongs to the mixed sub-region, generating a plurality of planting layout modes of the suitable grass seeds; Step 33: simulating each planting layout mode in the sub-region model respectively to obtain the vegetation survival rate corresponding to each planting layout mode, and when the heavy pollution sub-region belongs to the single sub-region, analyzing the vegetation survival rate of the suitable grass seed in the heavy pollution sub-region by using the sub-region model; Step 34: when the vegetation survival rate is lower than the specified survival rate, determining a plurality of heavy pollution positions corresponding to the heavy pollution sub-region by running the sub-region model, generating a soil improvement scheme corresponding to the heavy pollution sub-region in combination with the corresponding vegetation survival rate, and displaying the soil improvement scheme.

[0033] In this example, the specified number is 3; In this example, the heavy pollution sub-region represents a sub-region with severely polluted soil; In this example, the planting layout mode represents the layout condition when the optimal suitable grass species are planted in different mixing proportions; In this example, the survival rate is defined as 70% of the optimal survival rate.

[0034] The working principle and beneficial effects of the above technical solution are as follows: first, the single-species or mixed-species label divides the sub-region into single-species sub-region and mixed-species sub-region, and then matches the optimal suitable grass species according to the optimal survival rate, to ensure that the single-species sub-region focuses on the growth needs of a single grass species, and the mixed-species sub-region takes into account the synergistic needs of multiple grass species, avoiding unreasonable schemes caused by ambiguous region types; then, the sub-region model is constructed for the heavy pollution sub-region where the number of optimal suitable grass species is insufficient, to avoid neglecting such ecologically fragile regions due to limited grass species selection, ensuring that the ecological restoration of the entire construction region has no dead angles, especially suitable for the possible local heavy pollution problems in the rocky mountain power transmission project; for the mixed-species heavy pollution sub-region, the sub-region model simulates multiple planting layout modes and analyzes the survival rate, to find the most suitable layout mode for the heavy pollution environment, avoiding problems such as grass species competition or insufficient pollution tolerance caused by improper layout; the survival rate of the single-species grass species is simulated through the sub-region model, to predict the scheme effect before actual improvement, and if the survival rate is lower than the specified value, the strategy can be adjusted in advance to avoid resource waste and time delay caused by blind construction; finally, the specific heavy pollution positions of the heavy pollution sub-region are determined through the model, and the improvement scheme is generated in combination with the survival rate, to avoid indiscriminate improvement of the entire sub-region, greatly reducing the material cost and construction cost of soil improvement, especially suitable for wide-area construction regions in rocky mountain areas.

[0035] In embodiment 6, based on embodiment 5, the rocky mountain power transmission project ecological restoration method based on grass species growth trend further comprises: When the heavy pollution sub-region belongs to a mixed-species sub-region, a target planting layout mode with the highest vegetation survival rate is selected; According to the target planting layout mode and the growth trend of the corresponding suitable grass species, a corresponding pre-planting treatment mode for each heavy pollution position is generated; When the heavy pollution sub-region belongs to a single-species sub-region, a pre-planting treatment mode corresponding to each heavy pollution position is generated according to the growth trend of the suitable grass species; Meanwhile, a post-planting treatment mode for the heavy pollution sub-region is constructed according to the corresponding vegetation survival rate; According to the pre-planting treatment mode and the post-planting treatment mode, a soil improvement scheme corresponding to the heavy pollution sub-region is generated and displayed.

[0036] The working principle and beneficial effects of the above technical solution are: the soil quality is improved before and after planting, which can effectively reduce the phenomenon that plants are difficult to survive due to soil problems, and accelerate the efficiency of vegetation restoration.

[0037] In embodiment 7, the grass seed growth trend-based ecological restoration method for a rocky mountain power transmission and transformation project, step 4, comprises: Step 41: Selecting a corresponding grass seed planting layout for each sub-region, respectively, and guiding the on-site personnel to plant grass seeds, and obtaining the corresponding vegetation growth characteristics of each sub-region within a specified supervision period after the grass seed planting in the construction area is completed; Step 42: Constructing the vegetation growth situation of the corresponding sub-region according to the corresponding vegetation growth characteristics within different specified supervision periods, and determining the vegetation restoration speed corresponding to each sub-region; Step 43: Determining the high-quality growth position and the low-quality growth position in the sub-region according to the vegetation growth situation, constructing the grass seed compensation scheme and the soil improvement scheme for the low-quality growth position, and constructing the soil moisture retention scheme for the high-quality growth position, generating and displaying the grass seed-soil restoration scheme corresponding to each sub-region.

[0038] In this example, the vegetation growth characteristics standard is the appearance characteristics of the standard vegetation in the construction area, such as plant height, coverage, and wilting rate. In this example, the specified supervision period is 30 days.

[0039] The working principle and beneficial effects of the above technical solution are: the vegetation growth characteristics are continuously obtained within the specified supervision period, so as to determine the vegetation growth situation and the vegetation restoration speed, effectively avoiding the omission of later problems caused by one-time acceptance after planting, and then dividing the high-quality growth position and the low-quality growth position according to the growth situation, formulating the grass seed compensation and soil improvement scheme for the low-quality position, and formulating the soil moisture retention scheme for the high-quality position, so as to ensure that the restoration quality of all positions in the sub-region meets the standard, especially suitable for the characteristics of complex terrain and large local environmental differences in rocky mountainous areas. In this way, by accurately positioning the low-quality growth position, the grass seed compensation and soil improvement are only carried out in the problem area, without the need to re-plant or comprehensively improve the entire sub-region, thereby reducing the waste of grass seeds, fertilizers, manpower, and other resources.

[0040] In embodiment 8, the grass seed growth trend-based ecological restoration method for a rocky mountain power transmission and transformation project further comprises: When the number of first positions of the high-quality growth position in the sub-region is greater than the number of second positions of the low-quality growth position, it is determined that the sub-region completes vegetation restoration.

[0041] The working principle and beneficial effects of the technical solution are as follows: when a part of the sub-region presents a high-quality growth position, it is determined that the sub-region has completed vegetation restoration.

[0042] Embodiment 9 provides a rocky mountain power transmission project ecological restoration system based on grass seed growth trend, as shown in the figure, comprising: Figure 2 A sampling analysis module is configured to sample the field environment of the construction area, derive a plurality of field environment characteristics of the construction area, and determine a corresponding sub-comprehensive field environment characteristic of each sub-region in the construction area.

A long-term supervision module is configured to generate and display a grass seed-soil repair scheme for each sub-region according to a vegetation growth status corresponding to each sub-region after the construction area completes grass seed planting.

[0043] In this example, the field environment characteristics represent the soil, moisture, climate, and pollution characteristics of the construction area. In this example, the sub-comprehensive field environment characteristic represents the comprehensive result of all environment characteristics in a sub-region. In this example, the grass seed library represents a database that collects a plurality of grass seeds and their attributes, and the grass seed library is connected to big data for periodic updating. In this example, the optimal survival rate represents the maximum probability of survival of the suitable grass seed in the sub-region.

[0044] ​The working principle and beneficial effects of the above technical solution are as follows: in order to accurately plan and dynamically repair by region, bring significant beneficial effects from the dimensions of ecological restoration efficiency, adaptability and sustainability, first, the sub-comprehensive field environment characteristics of the sub-region are deduced through field sampling, and the differences of different sub-regions in rocky mountainous areas are targeted, then the optimal survival rate is deduced combined with the growth trend of suitable grass species, instead of only relying on basic adaptability screening, which can preferentially select grass species that grow fast, have developed root systems and strong stress resistance in specific sub-regions, further construct a soil improvement scheme according to the sub-comprehensive field environment characteristics, optimize the soil conditions before planting grass species, avoid the phenomenon that grass species do not survive due to poor soil foundation, finally construct a long-term soil improvement scheme, which can timely respond to problems after planting, dynamically adjust soil repair measures to ensure the continuous growth of vegetation, and avoid the ecological restoration halfway, in this way, from environmental sampling, grass species screening to scheme formulation and dynamic adjustment, a standardized process is formed, each step has a clear basis, which is convenient for supervision parties to track repair progress and quality, ensures that ecological restoration work is implemented according to the plan, and avoids formal repair.

[0045] In the embodiment 10, on the basis of the embodiment 9, the sampling analysis module comprises: A range determination unit is configured to acquire construction process data of the power transmission and transformation project, construct a virtual construction process of the construction area, deduce a plurality of estimated soil hazards caused by the power transmission and transformation project to the construction area, and determine a field hazard range corresponding to each of the estimated soil hazards. A sampling execution unit is configured to perform field soil sampling on each of the field hazard ranges respectively, analyze a plurality of field soil hazards presented in each of the field hazard ranges according to the sampling samples, and re-perform field environment sampling on the corresponding field hazard range when the field soil hazards do not match the corresponding estimated soil hazards. A trend analysis unit is configured to analyze the hazard spreading trend of each of the construction areas according to the field soil hazards combined with the topographic features and climate features of the construction area, generate a plurality of field environment characteristics of the construction area, and identify the field hazard situation of each of the field hazard ranges corresponding to the field environment characteristics. A feature generation unit is configured to perform same-type fusion on the field hazard situations corresponding to field hazard ranges having adjacent relationships, divide the construction area into a plurality of sub-regions according to the fusion results, and construct a sub-comprehensive field environment characteristic corresponding to each of the sub-regions according to the corresponding field hazard situation.

[0046] In this example, the estimated soil hazard means that the hazards caused by the power transmission and transformation project to the soil in the construction area are analyzed by estimation. In this example, the field hazard range indicates the range of the construction area affected by the same type of estimated soil hazard; In this example, the field soil hazard and the estimated soil hazard are not matched, indicating that the previous sampling and estimation work has a large error; In this example, the hazard spread trend indicates the characteristics of a field soil hazard when it spreads in the construction area; In this example, the same type of fusion indicates the process of regarding adjacent field hazard ranges belonging to the same type of field hazard as a larger range.

[0047] The working principle and beneficial effects of the above technical solutions are as follows: first, a virtual construction process is constructed through construction process data, the possible estimated soil hazards of the power transmission and transformation project are deduced in advance, and the hazard range is determined to avoid missing potential hazards that may be ignored only by relying on field sampling; then, the actual hazards are analyzed through field soil sampling and compared with the estimated hazards, and if they are not matched, the sampling is re-performed, which can correct the deviation of the virtual deduction in time, ensure that all existing soil hazards are identified, further analyze the hazard spread trend in combination with the soil hazards, terrain characteristics, and climate characteristics, so that the subsequent repair scheme not only targets the current hazards, but also takes measures to block the spread in advance to avoid further expansion of ecological problems, and finally, adjacent and similar hazard areas are fused and divided into sub-regions, ensuring that the ecological problem characteristics of each sub-region are uniform, the grass species and soil improvement scheme matched subsequently can accurately adapt to the core problems of the region, and the repair effect of the unified scheme for regions with large differences is avoided.
