Abstract

The embodiment of the invention provides a method and a device for obtaining the natural equal indexes of provincial cultivated land, and belongs to the technical field of cultivated land quality evaluation. The method comprises the following steps of screening each alternative index according to a correlation coefficient between each alternative index and a correlation coefficient between each alternative index and a reference value of a cultivated land natural equal index of each village and town in a province domain, and taking the screened alternative index as a grading index; regression is carried out on the value of each grading index of each village and town and the reference value of the cultivated land natural equal index of each village and town, and the influence weight of eachgrading index on the cultivated land natural equal index of each village and town is determined; and according to the value of each grading index of each village and town and the influence weight corresponding to each grading index of each village and town, determining the cultivated land natural equal index of each village and town in the provincial region. The cultivated land quality can be evaluated from a macroscopic perspective, and the spatial non-stationarity of the grading indexes is considered, so that the cultivated land quality can be evaluated more objectively and accurately.

Description

Technical field [0001] The invention relates to the technical field of cultivated land quality evaluation, and in particular to a method and device for obtaining natural indexes of provincial cultivated land. Background technique [0002] At present, the protection of cultivated land is facing new situations and requirements. It is necessary to further promote the construction of ecological civilization and implement protection from the three aspects of the quantity, quality and ecology of cultivated land. This requires a further deepening of the essence of cultivated land quality. As people pay more and more attention to the quality of cultivated land, it is of great significance to evaluate the quality of cultivated land in the province from a macro perspective. [0003] In related technologies, the most commonly used method to obtain the natural index of cultivated land at the provincial level is to obtain the value of each index through sample surveys in the county area, and de...
