Abstract

The invention provides a method and a system for determining protection density of an ecological filter zone. The method comprises the following steps: selecting a plurality of sample fields in the ecological filter zone according to different vegetation densities of the ecological filter zone, wherein the vegetation densities of the sample fields are varied in a gradient way; arranging a plurality of sampling points in each sample field; detecting the concentration of each nutrient substance at each sampling point in each sample field, and calculating the concentration of each nutrient substance of each sample field according to the concentration of each nutrient substance at each sampling point in each sample field; establishing a multi-element linear regression model according to the concentration of each nutrient substance of each sample field and the vegetation density of the ecological filter zone corresponding to each sample field; establishing a relation model of the protection density and water quality according to the multi-element linear regression model, and determining the protection density of the ecological filter zone according to the relation model of the protection density and the water quality. By adopting the method and the system, the optimum ecological filter zone protection density can be reasonably and quantitatively determined, the purification of the water quality can be better realized, and the ecological benefit can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of ecological filter belt design, in particular to a method and system for determining the protection density of an ecological filter belt. Background technique [0002] The river (lake, reservoir) bank ecological filter zone is located in the interlaced zone of water and land habitats, and is one of the important components of the forest ecosystem. Its ecological effect is mainly reflected by the vegetation in the ecological filter zone controlling the water body and the overall land habitat. Since the size of various ecological functions of the ecological filter zone is affected by the vegetation configuration structure of the ecological filter zone, different planting densities of vegetation on the ecological filter zone determine different ecological effects. Previous studies on the planting density of vegetation in the ecological filter zone were only based on the planting density specified in the loca...
