Embodiment Construction

[0008] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings and specific conditions.

[0009] Depend on figure 1 Provide, the inventive method comprises the following steps in concrete implementation: 1, according to the basin water resource, utilize the characteristics of a plurality of gate dams 2 on the river 1 that the water quantity is short of, carry out flow regulation and control to the river that the water quantity is short of by regulating and controlling the gate dam 2, Improve the environmental flow of the river; 2. Utilize the trapezoidal spur 3, the water storage weir 4, and the ecological island 5 on the river 1 to improve the river habitat, so that the river can form a variety of water flow habitat conditions, and provide habitats for fish, benthic animals and microorganisms. Breeding space; 3. Construct biological functional groups, release emergent plants, submerged plants...

Abstract

The invention aims to provide a method for recovering biological diversity in shortage of water. The method comprises the following steps: (1) regulating and controlling the flow of the river in shortage of water through the regulation and control for the gate dams by tilizing the characteristic of multiple gate dams of the river according to the basin water resource, thereby improving the river environment flow; (2) forming various habitat conditions of the river by utilizing the habitat improving technique for trapezoid spur dike, water storage weir and eco-island river; (3) constructing a biological functional group, putting emergent aquatic plants, submerged plants, benthonic animals and fish aquatic animals, constructing the aquatic plant and animal functional groups for recovering the biological diversity, gradually forming an artificial biocenosis of the river lack of water and finally forming an ecological system, thereby recovering the aquatic organism diversity in river in shortage of water. The method provided by the invention is unique, the operation and the application are easy, the effect is excellent and the method is beneficial to the recovery of the aquatic organism diversity in river in shortage of water and has obvious economical and social benefits.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a method for restoring biodiversity in water-deficient rivers. Background technique [0002] Rivers are responsible for regulating regional water volume, maintaining environmental humidity, and providing water for people's production, life, and agriculture. Because of their economic and ecological value, rivers have become non-renewable and alternative resources. The water volume of most rivers in northern my country is relatively small, and the seasonality is obvious. The water volume is relatively abundant in the wet season, but the water shortage is serious in the dry season. Therefore, traditional river management is mainly based on flood control and water storage. In order to meet the requirements of flood control, dredging of river channels and heightening of embankments are adopted, and hard revetments such as reinforced concrete, masonry, and gabions are used to f...
