Abstract:

Major function oriented zoning (MFOZ) is one of the effective ways to coordinate current rapid economic development and resources and environmental protection in China.Therefore,we set up an integrated indicator system of MFOZ in Yixing of Jiangsu Province, an area with intensive urbanization in the Yangtze River Delta of China.The indicators' weights were determined by principal component analysis (PCA).And then, the projection values of resources and environmental restriction,present development intensity and future development potential in Yixing were calculated by grey relation projection model (GRPM) and classified as three grades (high,medium and low),respectively.According to each town's combination of resources and environment,development intensity and development potential,Yixing was divided into five main function oriented zones by three dimension magic cube classification method (TDMCCM),which consisted of optimized and integrated zone,emphasized development zone,moderately development zone,agriculture and forestry development zone and ecological protection zone.The zoning result prominently indicates the “major function” characteristics of major function oriented zone,which gradually changes from protection type to development type.Moreover,the projection value of evaluation sample calculated by GRPM is the product of the sample module and the angle cosine between evaluation sample and ideal sample. It makes the evaluation results more comprehensive and accurate
