Method and system for calculating pressure of land resources utilization

Abstract

The invention provides a method and system for calculating a pressure of land resources utilization. An existing available land area is obtained by using a remote sensing image method and land utilization use type classification is carrying out by applying a classification method based on a decision-making tree, so that the land resource state obtaining becomes intelligent; overall land utilization planning is used as a source of a regional land utilization pressure, so that the land utilization pressure result becomes reasonable; and according to the purpose of land utilization, land utilization types are classified, the land resources of a target area are divided into multiple regions, and the land utilization pressure values and comprehensive pressure values of different regions are calculated respectively, so that the land management and decision formulation staff can the total state of the land utilization pressure of the certain area rapidly. And on the basis of standardized classification, the standardized pressure values are classified into ones in a low-pressure state, a high-pressure state, and a middle pressure state; and the leading land pressure of the land is determined, so that the reference is provided for sustainable land utilization and land type transferring of the local government and the superior government.

Description

technical field [0001] The invention relates to the technical field of land planning, and more specifically, to a method and system for calculating land resource utilization pressure. Background technique [0002] Land is the material basis for human survival and development. Human beings meet their various needs through the development and utilization of land resources. With the growth of population and the development of urbanization, people's demand for land resources is increasing, but the supply of land resources is limited. Different interest groups have different interests in the use of land resources, and the competition of land resources is highlighted. come out. The multi-suitability of land resources is another reason for land resource competition. Land resources with superior natural conditions and location conditions can often meet people's various needs. The competition of land resources is manifested in the competition of various land use modes for land un...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides a land resource utilization pressure analysis method and system that overcomes the above-mentioned problems or at least partially solves the above-mentioned problems, and solves the lack of flexibility in the existing research on land use pressure and the inability to combine with the adjustment trend of land use structure Combined with the overall land use planning data, it can quickly and accurately determine the land use pressure in a certain area, and provide decision support for land managers and policy implementers
