Embodiment 1

[0052] Firstly, the water depth range of 0-0.5 meters at the junction of water and land is designated as the implementation area, and the garbage, animal and plant residues in the implementation area are cleaned up.

[0053] According to the substrate conditions in the implementation area, it is decided whether to modify the substrate. Common modification methods include adding soil disinfectants, soil trace element nutrients, and substrate modification microorganisms.

[0054] According to the distribution of water depth and water quality in the planting area, the planting ratio of aquatic plants is designed.

[0055] Planting aquatic plants, planting aquatic plants by cuttings, such as figure 1 As shown, it includes all aquatic plants in areas 2 and 3.

[0056] Artificial maintenance of aquatic plants adjusts the ecological niches of different types of plants according to seasonal changes to achieve the maximum plant coverage. Figure 4 shows different changes with different...

Abstract

The invention discloses a water ecological restoration system and method for a shallow water area. The water ecological restoration method comprises the following steps: defining a water and land boundary within a water depth range of 0-0.5 m as a planting area; the planting area comprises an emergent aquatic plant or hygrophyte system which is planted along one side of the land and has small plants, and a submerged plant system which is planted along one side of the water area. The small emergent aquatic plant or hygrophyte system planted along one side of the land comprises one or more of myriophyllum elatinoides, hydrocotyle verticillata, cress, alternanthera philoxeroides, polygonum hydropiper, ottelia alismoides, rhizoma alismatis, leersia hexandra and aponogeton lanokenensis; and the submerged plant system planted along one side of the water area comprises one or more of ponceai, marina, marina and nutria. The defect that in general water ecological restoration, the shallow water area is prone to alopecia areata can be overcome, the water quality of the shallow water area can be purified, the coverage degree of aquatic plants in the shallow water area is remarkably improved, and the shallow water area underwater grassland is formed.

Description

technical field [0001] The invention relates to the fields of water ecological construction, water landscape, and river and lake water environment management, and specifically relates to a water ecological restoration system and method in shallow water areas. Background technique [0002] In recent years, with the concept of ecological development and sustainable development deeply rooted in the hearts of the people, the use of ecological methods to control the water environment of rivers and lakes has become more and more common. Restoring the water environment with ecological methods not only helps to improve the water quality of rivers and lakes, but also has eco-friendliness and good landscape. [0003] The current ecological restoration method is mainly by constructing a food web chain composed of microorganisms-aquatic plants-aquatic animals, using the material cycle and energy cycle of the food web chain to convert the pollutants in the water body into animal and plan...
