Abstract

The invention discloses an ecosystem attribute component composition structure description method fusing attribute grading information, and relates to an ecosystem attribute component composition structure description method. The method aims to solve the technical problem that an existing attribute component composition structure expression mode is not easy to grasp and understand a macroscopic pattern. The method comprises the following steps: 1, establishing a vegetation index attribute grading system of attribute components; and 2, generating component frequency distribution of the fusion attribute grading information. The remote sensing vegetation indexes used for expressing ecosystem component attributes are graded to form a qualitative grading system capable of expressing attribute size differences, so that on the basis of quantitative description of ecosystem attribute component composition structures by utilizing vegetation index component frequency distribution, qualitative grading information of the attributes is added, the overall condition of the attribute component composition structure of the ecosystem can be visually reflected, and the description method of the attribute component composition structure of the ecosystem can be perfected. The invention belongs to the field of ecosystem attribute structure description.

Description

technical field [0001] The invention relates to a method for describing the component structure of an ecosystem attribute. Background technique [0002] The patent "Description Method of Ecosystem Attribute Component Structure Based on Remote Sensing Vegetation Index" introduces the component frequency distribution of remote sensing vegetation index into the description of ecosystem attribute component structure, but when analyzing the composition structure of ecosystem attribute components , the above method uses the continuous variable of vegetation index directly for the quantitative description of the composition structure of the ecosystem attribute components. Although the expression method of the attribute composition structure is meticulous and accurate, it has the disadvantages that the macroscopic pattern is difficult to grasp and understand. It is not conducive to the correlation analysis between the spatial structure and the composition structure of the ecosystem....
