Problems solved by technology

[0003] In the existing technology, the development and division of cultivated land reserve resources are mainly classified through the traditional clustering method based on attribute similarity, and the spatial neighbor relationship is less considered; in the selection of clustering variables, most of them only consider natural resources. attributes and location conditions, less consideration is given to its spatial distribution characteristics, which makes the development of reserve resources of cultivated land unreasonable

Abstract

The invention discloses a method and a system for developing and zoning provincial cultivated land reserve resources, capable of rationally developing and zoning provincial cultivated land reserve resources. The method includes: evaluating the development suitability of the provincial cultivated land reserve resource blocks to be developed, wherein the evaluation grades of the development suitability evaluation include most suitable, moderately suitable and barely suitable; unit, based on the evaluation results of the development suitability evaluation, calculate the comprehensive suitability index, contiguous area index and development potential index of each unit’s cultivated land reserve resources; use the Delaunay triangulation algorithm and the SKATER algorithm to calculate the cultivated land reserve resources of each unit The resource comprehensive suitability index, contiguous contiguous index, and development potential index are used as clustering variables for spatial clustering, and the development zoning of the provincial cultivated land reserve resources is carried out.

Description

technical field [0001] The invention relates to the field of development and utilization of cultivated land reserve resources, in particular to a provincial cultivated land reserve resource development zoning method and system. Background technique [0002] Cultivated land is the basis of agricultural production and is related to national food security and social stability. With the accelerated pace of urbanization and industrialization, under the circumstances that economic construction inevitably occupies the existing cultivated land, it has become an important measure for the protection of cultivated land and food security in my country to develop a part of reserve resources of cultivated land in an appropriate amount to ensure the dynamic balance of cultivated land. The scientific and rational development and utilization of reserve resources of cultivated land is conducive to the sustainable use of land resources and ensures the quality of cultivated land. For ecologica...
