Functional Zoning of Land Use Based on Principle of Coupling Relationship

The purpose of this paper is to discuss the idea of functional zoning of land use under new circumstances basing on the principle of coupling relationship between land use and social economic development,which can provide references for the adjustment of regional land use.The case study of this paper selects Liucheng County of Guangxi Province as an example.The functional zoning of land use is determined according to the spatial combination of indices of the land development and land preservation,which are assessed in terms of the coupling relationship amongst basic divisional units.The results indicate that the land use,economic development level and carrying capacities of resources and environment in each divisional unit can be better matched through land zoning,such as optimized development zone,important development zone,moderate development zone and development-prohibited zone.It is concluded that the land zoning plan and results can clearly reflect the relationship between changes in regional land use and social economic development.It can further accelerate the compatibleness among land use,economic zoning,and carrying capacity of resources and environment,and also enhance the sustainable development ability.
