specific Embodiment

[0132] The embodiment of the present invention provides a method of regional land use control policy simulation and effect analysis, such as the evolution of urban land use, etc., implemented according to the following steps:

[0133] Step 1: Data determination. The data used in the present invention include land use status map, regional population data, GDP data, statistical data of the area of ​​each land use type, vector data of environmental elements, such as appropriate distribution of schools, hospitals, and roads.

[0134] Step 2: Construct the system dynamics sub-module. according to figure 2 The system flow diagram provided constructs the various formulas in the system dynamics sub-module. This module mainly constructs the total changes of population, GDP and each land use type based on the macro-population policy, economic policy and land policy.

[0135] Step 3: Construct the GIS sub-module. This module is mainly used to import the vectorized macro policy into t...

Abstract

The invention discloses a regional land use control policy simulation and effect analysis method, and relates to the field of land use and cover change simulation. By integrating the system dynamics model, the cellular automata model and GIS, the method realizes the real-time data exchange between the three at the grid level, realizes the effective interaction between graphs and numbers, and improves the efficiency of land use change. The accuracy of the simulation can expand the scope of application of the model, and provide better auxiliary tools for the regulation and control of land policies, which can be effectively used in the simulation and effect analysis of land use regulation policies in various regions, dimensions, and scales.

Description

technical field [0001] The invention relates to the field of land use and cover change simulation, in particular to a regional land use control policy simulation and effect analysis method. Background technique [0002] The simulation and effect analysis of land use regulation policies have always been very important for government decision-making and planning. The change of land use is disturbed and affected by human factors to a large extent, so it is of great practical significance to efficiently manage limited land and realize the sustainable development of land use. [0003] Since the advent of Geographic Information System (GIS), it has experienced four stages of development: start-consolidation-promotion-prosperity. The development of computer software and hardware in the 20th century has accelerated the development process of GIS. GIS has powerful spatial processing, computing and analysis capabilities, which can be used for data acquisition, storage, management, an...
