Research And Application On The Key Technology Of Main Function Zoning In Guizhou Province

The outline of the Eleventh Five-Year Plan goes like this: According to resources environmental carrying capacity, the existing development density and development potential, considering China' s future population distribution, economic layout, landuse and urbanizating patterns, land space will be divided into four key function zones including optimizel development zone, major development zone, restricted development zone and the prohibited development zone. This is a great strategical adjustment and transformation of our economic and social development, and it also an important and urgent task during the eleventh Five-year plan periol and in the near future. Now, the principal Function zoning is started up throughout the country and some provinces had complished the study of zoning. The need is urgent to establish the different corresponding theoretical and methodological system to direct the practice of main function division in different zones.In this paper, according to the regional characteristics of Guizhou Province, the technical approach of local major function zoning was studied. On the basis of "Technology Regulation of Major Function Zoning on the provincial Level", the index system was established, which included ten index. In this index system, five index including available land resource, available water resource, ecosystem frangibility, ecofunction importance and natural disaster risk were revised. The methods of date processing and computation were analyzed, which included index assignment, grade division, date normalization and weight assessment. Following the RS and GIS technical approach, the zoning method of Guizhou Province were analyzed and also some question were put forward for further study.
