主体功能优化开发县域的功能区划探索——以浙江省上虞市为例

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

选择典型县域,探索主体功能背景下的县域功能区划,为"十二五"期间我国主体功能区规划的深入实施提供借鉴,也为目前学术界有关地域功能区划的研究提供案例。本文选择空间差异显著的浙江省上虞市,探讨主体功能优化开发背景下县域功能区划的一般原则、区划思路和指标体系。基于土地开发适宜性评价,以及主要自然、人文要素空间分异的分析,按照国家主体功能区规划的部署,估测了上虞市在现状技术水平下土地开发强度的合理值,提出了2级4类的功能区划方案。

The ＂Eleventh Five-year Plan＂ divides national functional zones into the 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 the 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 the ＂red line＂ areas of spatial governance should be made definite.In the view of the above,choosing a typical county area and exploring its functional oriented zoning,its major function will play a big role in the national＇s spatial planning in ＂the Twelfth Five-year Period＂,and it will provide experience to study the functional oriented zoning which is the theme of MFOZ for the 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： the 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 the final result covers the whole county areas.The second level is zones to implement regional policies.The basic unit is natural landscape or plot,and the result does not cover the whole areas. This paper evaluates land development suitability and analyses the spatial distribution of major natural and human factors.On this basis,it estimates the rational value of Shangyu′s land development intensity according to the 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%.
