Problems solved by technology

The cascade treatment system can increase the residence time of water flow and enhance the removal of pollutants, but one of the biggest disadvantages is that this invention is mainly aimed at the prevention and control of water body pollution in steep slope waters. It is difficult to build a cascade treatment system in places with small slopes, and it has limitations in popularization and use. Therefore, it is still necessary to design a vegetation buffer zone that can be widely promoted, has a simple construction method, and can function for agricultural non-point sources. Pollution Prevention

Abstract

The invention discloses a vegetation buffer strand with an optimized water flow path and a construction method. The vegetation buffer strand is applied to building of vegetation buffer strands of a slope land. The vegetation buffer strand is characterized by comprising a plurality of downward recessed ecological small filter tanks arranged on a slope land, the depth of each ecological small filtertank is 4-5cm, the distance between adjacent ecological small filter tanks is 10-20cm, the length of each ecological small filter tank is 20-30cm along a slope direction, the width of each ecologicalsmall filter tank is 20-30cm in a direction perpendicular to a slope, and herb plants are planted in the ecological small filter tanks and spaces among the ecological small filter tanks. Runoff flowvelocity is reduced, eroding of runoff flow for the surface is reduced, water and soil loss is relieved, the downward recessed ecological small filter tanks are artificially built, staying time of water flow in the buffer strand is prolonged, and the agricultural non-point source pollutant removing function of plants is enhanced.

Description

technical field [0001] The invention relates to the technical field of environmental protection and water and soil conservation, in particular to a vegetation buffer strip with optimized water flow path and a construction method. Background technique [0002] With the further control of point source pollution, the problem of non-point source pollution has attracted attention. Agricultural non-point source pollution caused by agricultural production and rural life has become the main source of water environmental pollution, seriously threatening the safety of water environment. Vegetation buffer strips can effectively intercept agricultural non-point source pollutants (including nitrogen, phosphorus nutrients and suspended solids), and are widely used in the prevention and control of agricultural non-point source pollution and water pollution control. The vegetation buffer zone can intercept and remove agricultural non-point source pollutants through complex processes such as...
