A plant optimal allocation method for point source pollution interception and water purification in wetland lakeside zone

Abstract

The invention discloses a plant optimal configuration method for intercepting non-point source pollution and purifying water in wet land lakeside areas. The method comprises the step of plant optimal configuration for shore, lake-land ecotone and nearshore water, wherein the horizontal structure of the colonies for the plant optimal configuration shows the distribution of terrestrial plant zone, hygrophyte zone and aquatic plant zone in turn, the spire awns are planted in the terrestrial plant zone, carex dispalata is planted in the hygrophyte zone and dense eel grass is planted in the aquatic plant zone. The invention provides a plant community with an ecological function and a landscape benefit; through the optimal configuration for the plant community, the non-point source pollution, such as, overland runoff, of the natural water in lakes and rivers can be effectively intercepted; the pollution in the water in the wet land lakeside areas can be absorbed and cleaned; the survival rate of the plant community in the wet land lakeside areas can be increased.

Description

technical field [0001] The invention belongs to the field of environmental ecological restoration, and specifically relates to a plant optimization configuration method for improving the survival rate of lakeside plant communities, improving the efficiency of lakeside pollution interception and nearshore water purification treatment, and reducing the engineering cost of ecological system construction. Background technique [0002] Wetland plants are an important part of the wetland lakeside zone. They remove harmful substances such as nitrogen, phosphorus, and suspended solids in natural water bodies through their own metabolism, absorption, adsorption, and interception. One of the more effective methods and approaches. In terms of water or sewage purification application of wetland plant species, aquatic plants are the main types at home and abroad. The most commonly used wetland plants mainly include reeds, cattails, rice, grass grass, wild rice stems, black triangular, wa...

Problems solved by technology

[0003] However, in the practice of plant collocation or mosaic combination, due to the possible growth inhibition between different plants and the natural withering and renewal of the plants themselves, there are often phenomena such as low plant survival rate and unstable water quality treatment effect, and insufficient Considering the overall landscape benefits, that is, it is impossible to realize the multiple functions of pollution interception, water purification, stable ecological functions and good landscape effect creation at the same time, which makes the configuration model unable to be widely used
