It is worth to be noted that, the ecological system restoration of the river heart island is mainly realized by reconstructing a habitat, which is an ecological environment in which species or species populations depend for survival, and the habitats of different types of areas are different, so that it is necessary to divide the river heart island into areas and restore each area in a targeted manner.
Specifically, the environmental characteristics of the heart island are obtained, wherein the environmental characteristics are ecological factors including illumination, temperature, moisture, soil characteristics, terrain and the like, the heart island is divided into a plurality of different types of environmental areas according to the environmental characteristics, and the corresponding ecological restoration scheme is selected according to the type of the environmental area for ecological restoration based on the preset mapping relation between the environmental areas and the ecological restoration scheme. According to the embodiment of the invention, the river heart island can be divided into regions according to the acquired environmental characteristics of the river heart island, and an ecological restoration scheme is specifically distributed for each region to restore the ecological system of the river heart island.

when the environment area is a sludge accumulation area, the soil is fixed by adopting wood piles or rock blocks so as to reduce water and soil loss, and the physicochemical property of the soil is improved by adopting plants with developed root systems.
Specifically, the environment area comprises a hard substrate sludge environment area and a sludge accumulation area. Because the hard bottom mud environmental area is not beneficial to the growth of aquatic plants, a large exposed beach is required to be arranged for the inhabitation and propagation of large-scale waterfowls, and a small amount of or no artificial vegetation is planted. For the sludge accumulation part, wooden piles or block stones are adopted for fixation, so that water loss and soil erosion are reduced, proper soil and water environment are created for the growth of aquatic vegetation, and plants with developed root systems are selected to improve the physical and chemical properties of the soil.
In one embodiment, the method further comprises:
and when the improvement degree of the physicochemical property of the soil in the accumulated sludge area meets a preset recovery standard, adopting a preset plant community recovery strategy to construct a habitat.
Specifically, the accumulated sludge area is subjected to soil fixation through wooden piles or rock blocks, plants with developed root systems are planted to improve the physical and chemical properties of the soil until the physical and chemical properties of the soil meet preset recovery standards, and then a preset plant community recovery strategy is adopted to reasonably recover a plant community and construct a habitat suitable for inhabitation and propagation of specific species.
It is worth to be noted that the physical and chemical properties of the soil are physical and chemical properties of the soil, such as porosity, sand content, volume weight, softness, heavy metal content, trace element content, organic pollutant content, and the like.
In one embodiment, the plant community restoration strategy specifically comprises:

Furthermore, in order to form good landscape effect and rationality of vegetation distribution, configured modes are arranged in a staggered mode according to the land conditions of the river center island, and a landscape plant community mode combining arbor, shrub and grass is adopted. Referring to the vegetation arrangement diagram shown in fig. 2, when the water level is above the full-water period, woody plants are adopted to plant metasequoia, Chinese ash and the like, the inter-plant distance is 2 meters, medlar, paper mulberry and the like are irregularly arranged, and the inter-plant distance is 1 meter; and emergent vegetation is adopted from the rich water level to the normal water level, reeds, cattails, lotus flowers, water lily, water caltrops and the like are planted, the density is 15-20 plants per square meter, the effects of protecting soil and fixing slopes are achieved, and habitat is provided for wetland animals. Submerged vegetation is adopted below the normal water level, submerged plants such as watermifoil and tape grass are planted, and the water environment around the estuary island is improved.
In one embodiment, the specific variety of the vegetation sequence is determined by:
acquiring the geographical position of the river center island;
inquiring a preset waterfowl distribution condition database, and determining the local waterfowls according to the geographical positions;
