[0013] To more clearly illustrate the technical solutions in the embodiments of this application, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.
[0014] Figure 1 This is a structural diagram of an embodiment of the device of this utility model;
[0015] Figure 2 This is a modified structure according to an embodiment of the present utility model. Detailed Implementation
[0016] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.
[0017] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.
[0018] like Figure 1 and Figure 2 As shown, through the optimization of the horizontal and vertical design of rivers, lakes, and woodlands, the drainage efficiency of green spaces is improved, and the effective storage capacity of the river network is enhanced during severe rainstorms. Through integrated water and green space design, the natural meandering and interdependent state of water and greenery is restored; the quality of forests and waterfront spaces is improved, and the quality and stability of the ecosystem are enhanced. Through the composite utilization of space, the storage capacity of rivers and lakes and forest coverage are increased; and the integrated coexistence and composite utilization of forest and water resources are achieved during river and lake management and afforestation.
[0019] Strengthen measures to prevent soil erosion on slopes and reinforce the toe of slopes, do not significantly reduce the cross-sectional area of river channels, take measures to regulate water levels in flooded areas, and create water forests.
[0020] The plan includes: establishing new forest and water system layouts, optimizing existing forest and water systems, afforestation within the river estuary, afforestation within the land management area of the river channel, and supplementing existing riverbanks with new forests and greenery.
[0021] Combination Figure 1 and Figure 2 The structure of one embodiment of this utility model specifically includes:
[0022] Phase 1
[0023] The earthwork modeling includes land part 1, first river natural slope 2 and second river natural slope 3. The earthwork modeling is designed with the natural river design estuary line or the design control water level constant water level interval as the boundary. The first river natural slope 2 is a first slope, the slope is not steep than 1:2, 1:3-1:5 is the best, the second river natural slope 3 is a second slope, the slope is fixed 1:2.5. At the same time, the effective planting thickness is not less than 70cm. Plus the humus culture soil. (Humus is a colloidal substance formed by the decomposition and transformation of organic matter by microorganisms, generally black or dark brown, which is the main component of soil organic matter (50%-65%). Humus is mainly composed of carbon, hydrogen, oxygen, nitrogen, sulfur, phosphorus and other nutrient elements, and its main types are humic acid and fulvic acid (also known as rich acid). Humus has moderate cohesiveness, can make clay loose, and sand cohesive, and is a good cementing agent for forming granular structure.)
[0024] It also includes woody plants 4 and emergent plants 5. The woody plants 4 in the legend are planted with 3-5 year old seedlings with soil balls without disassembling the grass rope method (false planting) with a specification interval of 2-3 meters. The excavation of the tree hole bottom is not higher than the upper limit of the constant water level interval in principle. The emergent plants 5 are planted in the constant water level interval. The part of the plant in the air has the characteristics of terrestrial plants, and the part growing in water (roots or underground stems) has the characteristics of aquatic plants. In the first stage, it acts as a natural cofferdam for soil slope water retention, reducing water movement speed and delaying water content of soil above the constant water level. Thus, the woody plants 4 in the figure only need to face the change of water content caused by heat in the soil during the domestication process of high water level, thereby adapting to the growth characteristics of high-humidity and high-heat soil.
[0025] Second stage
[0026] In the first stage, the land part 1, the first river natural slope 2 and the second river natural slope 3 are all stable, and the woody plants 4 in the figure are confirmed to survive. The function of the land part 1 is adjusted to a water-friendly slope space 6 for human activities, which is a recreational green space with a slope of 5.0%-20.0%. The water-friendly slope space for human participation has a water depth of 50cm within 2m of the slope. The woody plants 4 are transplanted to the planting submerged area 7, that is, the woody plant domestication is successful, and is permanently transplanted between the constant water level and the theoretical minimum water level, and is naturally planted to form a water forest. The wet area 8 between the constant water level and the highest water level is newly added, and the lawn and wet plants and wet-tolerant shrubs are added to improve the water and soil conservation of the land part 1.

Therefore, the appended claims are intended to be interpreted as including all changes and modifications falling within the scope of the present application.
[0028] Obviously, numerous modifications and variations of the present application are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the application can be practiced otherwise than as specifically described herein.
