摘要

The rational use of limited land resources is of great importance to the division of land space and the coordination of man land relationship, strictly implement the ecological function orientation of Karst mountain area, on the basis of scientifically defining three kinds of space: Town, agriculture and ecology, supported by RS and GIS means, combining the three kinds of spatial division results of town, agriculture and ecology, the optimal allocation of land resources is realized, using ArcGIS spatial overlay analysis, according to the evaluation model of available land resources and the classification standard of available land resources, the evaluation of the three kinds of space available land resources was carried out. It is beneficial to control and deploy land resources in the three types of space, realize the protection and restoration of the environment, maintain the structure of the ecosystem, and guarantee the ecological security of the region. The results show that, the available land resource is 204.79 km~2, overall distribution characteristics are more in the South than in the north and the East, more in the west, and lower in the terrain than in the terrain, per capita available resources is only 0.12 acres, the abundance of available land resources can be divided into three levels: rich, medium and relatively deficient, the area of available land resources in each functional space is sorted into ecological space, agricultural space and urban space. There is a certain spatial consistency between the three types of spatial scope and the available land resource evaluation results. The land resources use situation is relatively coordinated, and intensive use and protection should be strengthened.
