Visualized coupling coordination degree evaluation system of land utilization transition

Abstract

The invention provides a visualized coupling coordination degree evaluation system of land utilization transition. The system comprises a database, a state parameter selection module, a coordinated evolution simulation module, a development index calculation module and a coordination type determining module; the database stores original land utilization data of a target region; the state parameterselection module calculates the gray relation degree and selects four types of indexes with highest gray relation degrees in each subsystem as state parameters; the coordinated evolution simulation module calculates a relaxation coefficient according to index data of the state parameters, and selects six types of state parameters whose absolute values of the relaxation coefficients are minimal asorder parameters; the development index calculation module calculates a development index according to index data of the order parameters, and obtains the annular change speed of the development index of each subsystem by fitting according to years; and the coordination type determining module determines a coordination type of the target regional system. The system has the advantages that the development speed of three subsystem and the coupling coordination degree of the integrated system are calculated, the coupling coordination type is determined in a classified way, and possible risks inthe land transition process can be identified and avoided.

Description

technical field [0001] The invention relates to the technical field of land resource management, in particular to a visualization system for evaluating the coupling coordination degree of land use transformation. Background technique [0002] Land use transition, that is, driven by social and economic changes and innovations, a certain area is transformed from one land use form to another within a period of time. Land is a complete system, and the land use form Changes are often determined by various factors such as changes in population, economy, technology and other factors, as well as people's impact on land use systems, social production and lifestyles. The results of land use transition will lead to different degrees of changes in the economic, social and ecological aspects of a region. With the increasing speed and extent of land use transformation, the resulting actual conflicts and potential risks are becoming more and more prominent. Therefore, it is necessary to c...

Problems solved by technology

[0003] However, in the existing technology, there is no visualization system for evaluating the coupling and coordination degree of regional economic, social and ecological comprehensive systems guided by land use transition, which leads to low efficiency in the analysis of the impact trend of land use transition. Satisfying the demand for prediction of land use transition risks with a wide range and multi-factor risk assessment has a great impact on the risk assessment of land use transitions
