The invention relates to a land space partitioning method and device based on a minimum cumulative resistance model, and the method comprises the steps: obtaining the spatial data of a target region, obtaining the regions of ecological land and construction land of the target region, setting multi-dimensional resistance evaluation factors based on the spatial data and the evaluation indexes of the two types of land, constructing comprehensive expansion resistance based on the multi-dimensional resistance evaluation factors, respectively obtaining minimum cumulative resistance values of the two types of land in expansion based on a minimum resistance model and the comprehensive expansion resistance, and calculating a minimum cumulative resistance difference value of the two types of land in expansion based on the minimum cumulative resistance values, and based on the minimum cumulative resistance difference value and the corresponding grid number, carrying out land space partitioning on the target region, and outputting a partitioning result. The method has the advantages that low-efficiency and unreasonable land development is avoided to a certain extent, sustainable development of land resources is achieved, and a scientific basis is provided for territorial space zoning.
Description
Technical field [0001] The present application relates to the technical field of building regional ecological safety, in particular, to a country-based space partitioning method and apparatus based on minimum accumulation resistance model. Background technique [0002] With the acceleration of the urbanization process, the various resources facing the resources facing my country have become more serious. Different types of land use contradictions are increasingly prominent, and the regional spatial structure is gradually imbained. The difference in urban and rural development has continued to expand. Rationality and effective spatial planning has become a prerequisite for achieving sustainable development. [0003] The research of the relevant technical partition studies, in the country to start, early spatial partitioning methods, generally used as partition basis, lack of quantitative assessment of national standards, the prospective and scientificness of space configuration; T...
