[0002] Small watersheds usually refer to relatively independent and closed natural catchment areas with a catchment area of ​​less than 50 km2, bounded by the watershed and the downstream river outlet section below the second and third-level tributaries. They have complex topography, diverse hydrological conditions, rich soil types, and fragile ecological environment. Among them, for river areas with undulating longitudinal slopes, the riverbed scouring and silting changes greatly and the siltation is serious, which affects the discharge of floods during the flood season and seriously weakens the flood discharge capacity of the river.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] Please refer to Figure 1 , Figure 1 A flow chart of a small watershed river ecological management method provided in an embodiment of the present application. The small watershed river ecological management method of the embodiment of the present application can be applied to computer devices, including but not limited to smart phones, laptops, tablet computers, desktop computers, physical servers, cloud servers and other devices. Figure 1 As shown, the small watershed river ecological management method of this embodiment includes steps S101 to S105, which are described in detail as follows: Step S101, dividing the target small watershed river into a plurality of regulation river sections according to the river channel status information and surrounding information of the target small watershed river, wherein the regulation river sections include conventional protection river sections, ecological management river sections and ecological transformation river sections.

[0019] In this step, the target small watershed river is divided into multiple sections for regulation. Targeted regulation can be carried out according to the specific conditions of each section of the river and the characteristics of the surrounding environment, avoiding a one-size-fits-all approach and improving the regulation effect. By comprehensively considering surrounding information, such as land use, water quality, and ecosystem health, limited resources can be maximized, and comprehensive regulation of the river can be achieved to improve regulation efficiency and cost-effectiveness. At the same time, segmented regulation can help establish a long-term management and maintenance mechanism, and the governance results and problems of each river section can be more clearly evaluated and monitored, which is conducive to the long-term improvement and protection of the ecological environment.

[0020] In some embodiments, the step S101 includes: Using on-site survey equipment to collect the current information of the river channel of the target small watershed, and to obtain the surrounding information on both sides of the river channel of the target small watershed, the current information of the river channel includes river flow information, river bottom elevation information, river channel soil information and river channel pollution information, and the surrounding information includes village distribution information, farmland distribution information and factory distribution information; The river sections in the target small watershed where villages, farmlands or silt are distributed are classified as ecological management river sections; The river sections in the target small watershed where factories are distributed or the river sections with pollution levels greater than a preset value are classified as ecologically renovated river sections; Other river sections in the target small watershed that have not been classified as ecological management river sections and ecological transformation river sections shall be classified as conventional protection river sections.

[0021] In this embodiment, a drone carrying a high-resolution camera can be used to perform vertical and oblique photography of the target small watershed, and a three-dimensional image of the river and surrounding areas can be quickly obtained for analyzing river flow information, riverbed elevation information, river soil information, and river pollution information. Satellite remote sensing images can be used to observe changes in the target small watershed more macroscopically, including changes in the distribution of villages, farmland, and factories, as well as natural changes in the river. Ground monitoring stations can be set up on both sides of the river to monitor river water quality, water volume, sediment content, and river pollution information in real time. In this embodiment, the target small watershed river is segmented so that different rivers can be finely managed, avoiding the use of reinforced concrete revetments to prevent secondary damage to the ecology. The present invention is more in line with the ecological characteristics of small watershed rivers and can effectively improve the management effect and resource utilization efficiency.

[0022] Step S102, based on the preset regulation plans corresponding to the respective regulated river sections, an ecological regulation model of the target small watershed is simulated and generated.

[0023] In this step, the ecological governance model is a visualized river model after the simulated construction of the remediation plan. The simulated ecological governance model can be customized according to the specific preset remediation plan for each regulated river section, so as to formulate the most appropriate governance strategy for the characteristics and problems of different river sections to achieve the best ecological restoration effect. The model can comprehensively consider the characteristics of the river itself (such as flow, water quality, sediment content, etc.) and surrounding environmental factors (such as the distribution of villages, farmland, and factories), and can predict the development trend of the river ecosystem under different governance plans, which is helpful to evaluate the long-term effect of the governance plan, so as to provide a scientific basis and foresee possible ecological changes in the future. At the same time, this step can help optimize resource allocation, determine the human, material and financial resources required in the governance process, and improve governance efficiency and cost-effectiveness.

[0024] In some embodiments, the step S102 includes: For each of the regulated river sections, according to the reasons for the segmentation of the regulated river section, a preset regulation plan corresponding to the regulated river section is matched, and the preset regulation plan includes a bank protection project plan, a dredging project plan, a river dam project plan, a vegetation planting plan and a water purification plan; By using preset simulation construction tools and according to the preset regulation plan, simulated construction is carried out on the target small watershed river channel to generate the ecological management model after the simulated construction of the target small watershed river channel.

[0025] In this embodiment, each river section under renovation can match at least one of the bank protection engineering scheme, dredging engineering scheme, river dam engineering scheme, vegetation planting scheme and water purification scheme. For example, a conventionally protected river section can only match one bank protection engineering scheme without matching other schemes; an ecologically renovated river section can match the bank protection engineering scheme, dredging engineering scheme, river dam engineering scheme, vegetation planting scheme and water purification scheme respectively. The preset simulation construction tool can be a tool such as Synchro 4D, Navisworks, Revit, Civil 3D or Tekla Structures. This embodiment can simulate various possible risks and adverse effects through simulation construction tools, thereby helping to avoid potential ecological and environmental risks and ensure the long-term sustainability of ecological governance.

[0026] Step S103, in response to the user's adjustment operation, the model parameters of the ecological management model are adjusted until the user confirms that the adjustment is completed, and a target ecological management model of the target small watershed river is generated.

[0027] In this step, the user adjusts the construction plan according to actual needs to better suit the actual construction conditions of the river.

[0028] In some embodiments, the step S103 includes: In response to a user's scheme replacement operation, scheme deletion operation, scheme addition operation and / or scheme parameter change operation, the regulation scheme corresponding to the regulated river section in the ecological governance model is replaced, deleted, added and / or the parameters are changed; In response to the user's confirmation operation, the adjusted ecological management model is determined as the target ecological management model of the target small watershed river.

[0029] In this embodiment, the data of the current ecological governance model and the new solution requirements input by the user can be automatically matched and replaced, and the impact of the change can be evaluated; the impact of the new or modified solution can also be simulated in real time and integrated into the existing ecological governance model to achieve comprehensive governance coverage and effect evaluation. This embodiment supports users to dynamically adjust and confirm ecological governance solutions according to real-time needs, so as to better achieve the protection and sustainable development of the river ecological environment.

[0030] Step S104, using a preset small watershed ecological assessment model, the target ecological management model is assessed to obtain a small watershed ecological assessment result.

[0031] In this step, the preset small watershed ecological assessment model can be an assessment model in tools such as Synchro 4D, Navisworks, Revit, Civil 3D or Tekla Structures. This embodiment uses the preset small watershed ecological assessment model to assess the target ecological governance model, which can ensure the scientificity and comprehensiveness of the assessment, improve the assessment efficiency and decision-making quality, and promote the sustainable management and protection of the small watershed ecological environment.

[0032] In some embodiments, the step S104 includes: The preset small watershed ecological assessment model is used to simulate the flood conditions, drought conditions and factory sewage conditions in the target small watershed river, and the small watershed ecological assessment results of the target ecological governance model are evaluated. The small watershed ecological assessment results include the flood discharge capacity assessment results under flood conditions, the water storage capacity assessment results under drought conditions and the water purification capacity under factory sewage conditions.

[0033] In this embodiment, for example, for flood conditions, real-time hydrological data monitoring, such as rainfall, river flow, reservoir water level, etc., can be integrated, and a flood evolution model, such as a one-dimensional or two-dimensional fluid dynamics model, can be established to simulate the evolution of floods under different terrain and river conditions, so as to accurately simulate the flood discharge capacity of flood conditions. For example, for sewage discharge, environmental pollution data such as factory emissions, urban sewage and agricultural pollution can be integrated to establish a water quality model, such as a zero-dimensional or one-dimensional water quality model, to simulate the transport and mixing process of pollutants in the river and evaluate the water purification capacity. By simulating floods, droughts and environmental pollution, this embodiment can predict the ecological status of small watershed rivers under special events, so that the target ecological governance model is more in line with the ecological characteristics of small watershed rivers and ensures long-term and stable governance.

[0034] Step S105: If the ecological assessment result of the small watershed of the target ecological management model meets the expected result, comprehensive management construction is carried out on each regulation river section of the target small watershed river based on the target ecological management model.

[0035] In this step, optionally, if the small watershed ecological assessment result of the target ecological governance model meets the expected result, the remediation plan corresponding to the target ecological governance model is sent to the construction unit as the construction plan of the construction unit; For example, for ecological management river sections with villages and farmlands, gabion foot guards are used as revetment retaining walls, and the top surface of the gabion foot guards is paved with C30 concrete pavement and turf slope protection; For river sections with sediment accumulation, the riverbed is dredged and stepped waterfalls and hydrophilic stepping stones are used at the sediment accumulation locations. For ecologically renovated river sections where factories are distributed, gabion retaining walls are used on the river bank, and mortar-laid stone retaining walls are used at preset positions away from the shore. Connecting bridges are set up at the joints of the mortar-laid stone retaining walls and the gabion retaining walls to form purification pools through which river water can flow in and out, and vegetation is planted in the purification pools.

[0036] Among them, gabion foot guards are suitable for drainage ditches that are not restricted by terrain. Figure 2 As shown, the foot guard is divided into two layers, and each layer of gabion cage (galvanized, plastic coated) is 1m high. The gabion foot guard is used, the foot guard is 2.0m high, the designed burial depth is 1.0m, the wall top is 1.0m wide, and a 1.0m wide and 200mm thick C30 concrete pavement (pavement inlaid with river pebbles) is laid on the top of the wall. Before backfilling the earth, a layer of geotextile (300g / m2) should be laid on the backwater side of the wall as a filter layer. The gabion specifications are 2m×0.8m×1m and 2m×1.5m×1m. The top of the wall uses turf slope protection, and the bank slope is appropriately adjusted according to the existing terrain and controlled at about 1:1.5.

[0037] This embodiment can not only effectively solve the ecological and environmental problems of the river, but also improve the riverbank protection capacity and water quality, achieve the coordinated development of ecology and environment, and comply with the basic principles of sustainable governance and the needs of social and economic development.

[0038] In some embodiments, after step S103, the method further includes: If the ecological assessment result of the small watershed of the target ecological governance model does not meet the expected result, then output the ecological governance river section and the reason that does not meet the expected result in the target ecological governance model; Based on the reasons stated above, the plan for the ecological management river sections that do not meet the expected results will be modified; Based on the target ecological management model after the modification of the plan, comprehensive management construction is carried out on each river section of the target small watershed river.

[0039] In this embodiment, the ecological management river section that does not meet the expected results can be modified by user means or by system settings.
