Problems solved by technology

The current research is mostly scattered and empirical qualitative research, and systematic and quantitative research is still rare
Moreover, most of the existing methods are inefficient and cannot accurately construct the quantitative relationship between landscape patterns and ecological processes.

Abstract

The present invention proposes a method and a system for quantitatively associating a landscape pattern with an ecosystem service function. The method comprises: classifying the land cover type of a target area; and according to the to-be-evaluated ecosystem service function in the target area, evaluating spatial distribution results of the matter amount corresponding to the ecosystem service function in the target area; creating a grid layer of the target area; determining a landscape pattern feature value corresponding to each grid cell in the layer and a matter amount value corresponding tothe ecosystem service function, wherein the landscape pattern feature value is the ratio of the area occupied by the composition of the land cover type to the area occupied by each composition in thegrid cell, and the matter amount value is the average value of the spatial distribution results of the matter amount within the grid cell; and according to the landscape pattern feature value corresponding to each grid cell and the matter amount value, analyzing the quantitative relationship between the landscape pattern and the ecosystem service function. According to the method and system provided by the present invention, the quantitative association between the landscape patterns of different ecosystems and the ecosystem service functions can be effectively and accurately revealed.

Description

technical field [0001] The invention relates to the technical field of environmental ecology, in particular to a quantitative correlation method and system for landscape patterns and ecosystem service functions. Background technique [0002] Any ecological function depends on a certain landscape space, and the structure determines the function. There may be a single or two-way correlation between the two, and they have different spatial scale domain characteristics. Therefore, landscape pattern and ecological function are inseparable. The research tends to be an independent study of landscape pattern and ecological function, or simply classify the relationship between the two as a qualitative causal relationship. [0003] Currently, there is no good correlation method for the relationship between landscape pattern and ecosystem service function. Landscape pattern is mostly expressed by landscape pattern index. The pattern index has developed to the extent of large number, ...
