Abstract

The invention provides an ecological restoration method for lake oscillation water in a plain river network area. The ecological restoration method comprises the following steps: dividing a water area space into a shoal area, a transition area and a deep pool area according to a preset underwater elevation; according to the water body index data, judging key factors influencing the water quality in the shoal area and the transition area; according to a judgment result, respectively processing each subarea by adopting a mode of directly planting short eel grass or firstly carrying out turbidity reduction treatment and then planting the short eel grass; and then carrying out long-acting management and protection on the short vallisneria natans planted in the shoal area and the transition area. According to the method, the lake oscillation is subjected to zoning treatment, all the areas are treated in the mode including short vallisneria spiralis planting, long-acting management and protection are conducted on the short vallisneria spiralis in the later period, targeted zoning treatment is conducted on water ecological restoration of the lake oscillation, natural restoration of aquatic plants serves as the main body of restoration work, the later-period maintenance cost is low, and the method is worthy of popularization.

Description

technical field [0001] The application relates to the field of water environment management, in particular to a method for ecological restoration of lake dangling water in plain river network areas. Background technique [0002] The plain water network area is criss-crossed by rivers and ports and connected by lakes and lakes. It has unique ecological service functions such as pollutant interception, water purification, and eco-tourism. [0003] In recent years, due to the impact of regional urbanization, high-density water breeding, and increased pollution discharge, the wetland area of ​​the lake has decreased sharply, the ecological degradation of the water body has been seriously degraded, the biodiversity has decreased, the capacity of the water environment has decreased, and the self-purification capacity has decreased. The task of wetland ecosystem is arduous. Domestically, a lot has been done on the simple ecological restoration of river networks and lakes, mainly f...
