Construction Method of Urban Landscape Water Ecosystem

Abstract

The invention discloses a method for establishing an urban landscape water body ecological system. The method comprises the following steps: improving a water body substrate; planting submerged plants by using a method that upright posts are adopted to mark areas, so as to establish an underwater frost; planting layered emergent aquatic plants; putting zooplankton (daphnia magna) so as to improve the transparency of the water body; putting aquatic organisms such as fishes, shrimps and shells, so as to complete the water body ecological system; maintaining and managing the ecological system. Through the adoption of the method, the quality of the water body can be remarkably improved, the transparency can be greater than 2.0m, the quality can meet the III-type water quality standard for a long time, black, smell and dirty water bodies with blue-green algae can be thoroughly eliminated, and the water body is always kept clear completely.

Description

technical field [0001] The invention relates to water body ecological restoration technology, in particular to a method for constructing an urban landscape water body ecosystem. Background technique [0002] Urban landscape water body (lake) is a very important part of the urban ecological natural environment, which undertakes various functions such as flood control and drainage, adjustment of microclimate, maintenance of ecological balance, improvement of urban landscape, and provision of water for production and living. However, with the rapid development of urban industrialization and urbanization, the scale of cities and population pressure continue to expand, and the environmental load increases, making the water quality of urban lakes worse and worse, and the ecological system of lakes is also gradually degraded. It has become an important part of urban construction to increase the prevention and control of urban landscape water pollution and restore the ecological fun...

Problems solved by technology

However, at present, the existing treatment methods for eutrophic water bodies in urban lakes have defects such as relatively single measures, slow ecosystem recovery after implementation, and difficulty in long-term maintenance. In addition, the treatment costs are high, and some methods (such as chemical methods) are still There are secondary pollution problems, cyanobacteria blooms are prone to repeated outbreaks, and it is difficult to fundamentally solve the problem of eutrophication of water bodies
