Method and device for quantifying cultivated land damage degree evaluation index and storage medium

Abstract

The invention provides a farmland damage degree evaluation index quantification method and device and a storage medium, and the method comprises the steps: collecting the damage type of the farmland damage degree, and determining a plurality of evaluation indexes based on the damage type; obtaining an evaluation index list according to the damage type and the evaluation index, and uploading the evaluation index list to a cloud for storage; performing quantitative grading on the preset evaluation indexes called from the cloud to obtain a quantitative grading result; obtaining a preset evaluation index value based on the quantitative grading result, and determining the weight of each preset evaluation index according to the preset evaluation index value; calculating a comprehensive identification score value Y according to the damage type, a preset evaluation index value and a weight of a preset evaluation index; determining the cultivated land damage degree based on different numerical intervals of the comprehensive identification score value Y; and comprehensively evaluating the cultivated land damage from qualitative, quantitative and pricing according to different cultivated land damage degrees. According to the invention, the problem that the evaluation index data cannot be quantitatively analyzed is solved.

Description

technical field [0001] The present invention relates to the technical field of ecological risk assessment, in particular to a method, device and storage medium for quantifying the evaluation index of cultivated land damage degree. Background technique [0002] Although the total amount of arable land in my country is large, the per capita arable land is small, and the high-quality arable land is even less, and the distribution is uneven. In order to better protect the cultivated land, the ecological environment management methods of the third-party cultivated land damage appraisal agency have been introduced to conduct appraisal work on the degree of damage to the cultivated land ecology. [0003] Ecological risk assessment is an important means of ecological environment management, and its related research and technical applications have developed rapidly in the past ten years, and it is the basis of ecological security research. However, in the face of complex cultivated ...
