Study on Method of Overall Land Use Planning Based on Modelling Multiple General-Purposes

Land resources are the base for people's living and the most foundamental means of production, thus, their sustainable utilization is a key aspect of sustainable development of society. In order to realize the sustainable utilization of land resources, the method of the overall land use planning of general-purpose is put forward. It includes the establishing of land resource database, multisuitability land evaluation, general-purpose optimization of the land use structure and the ecological design of the land use system and distribution of land use on plane by applying GIS. It can optimize the structure of land use of Xushui County according to decision maker's requirement. The model is run to reach each goal, the solutions of the model are the nondominated solution sets. By analyzing and comparing each solution, scheme 2 of three typical planning schemes is satisfactory and recommanded. Finally, the ecological design and distribution of land use based on multisuitability land evaluation and scheme 2 are made.
