Function zoning of development-optimized area at a county level:A case study of Shangyu,Zhejiang

Abstract

The Eleventh Five-year Plan divides national functional zones into basic unit of county administrative division,which is called major function oriented zoning(MFOZ).According to general disposition of national MFOZ,central and provincial governments are implementing MFOZ strategy in unit of county administrative division.After prefectural and county level governments have implemented national MFOZ,the spatial development sequence should be specified,the development intensity should be limited,oriented zones should be designated and red line areas of spatial governance should be made definite.In view of above,choosing a typical county area and exploring its functional oriented zoning,its major function will play a big role in national's spatial planning in the Twelfth Five-year Period,and it will provide experience to study functional oriented zoning which is theme of MFOZ for present academic circles. The paper takes Shangyu as an example to study general principles,the train of thought and index system of county area functional oriented zoning.The oriented function zones of Shangyu should follow five principles,which are general principles of development-optimized county area:(1) area extropism;(2) based on population and industry spatial combined pattern;(3) spatial rational regulation and control,and intensive usage of land resources;(4) ecological preservation and construction of areas' integrality;(5) areas relatively concentrated and give consideration to town administrative units.Oriented function zones are classified into two levels: first level is fundamental zones to make clear next level's development,as well as to adjust and restrict areas' development limits.The basic unit is town and final result covers whole county areas.The second level is zones to implement regional policies.The basic unit is natural landscape or plot,and result does not cover whole areas. This paper evaluates land development suitability and analyses spatial distribution of major natural and human factors.On this basis,it estimates rational value of Shangyu′s land development intensity according to arrangment of national MFOZ.Furthermore this paper suggests a functional oriented zoning plan with 2 levels and 4 types.According to land development suitability evaluation of state technological and economic seedtime,the reasonable value of Shangyu′s land development intensity should not exceed 13%.
