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 ecological filter belt on the banks of rivers (lakes and reservoirs) is located in the water-land habitat interlaced area and is one of the important components of the forest ecosystem. Its ecological effect is mainly reflected by the vegetation control of the ecological filter belt and the overall habitat of the land. Since the size of the various ecological functions of the ecological filter belt is affected by the vegetation configuration of the ecological filter belt, the different planting densities of the vegetation on the ecological filter belt determine different ecological effects. Previous studies on the planting density of vegetation in the ecological filter belt were only constructed along the terrain according to the planting de...
