中文摘要：
土地利用分区是土地利用总体规划的核心内容之一,也是土地利用结构布局的体现和落实。为了对江苏沿海地区土地利用及未来发展方向提供理论指导,结合该区域土地利用的现状和特点,以国家主体功能区划分的评价指标为依据,选取了资源环境承载力、现有开发密度和发展潜力3个一级指标及12个二级指标,建立了土地利用分区的评价指标体系。借助SPSS软件,对江苏省沿海地区3个地市的20个行政单元进行了系统聚类分析。结合分区结果及沿海地区的实际情况,将该区域分为4类：优化发展区,包括南通、连云港和盐城3个市区;滨海潜力区,包括如东县、大丰市和东台市;重点发展区,包括海安县、启东县、如皋县、通州市、海门市;一般发展区,包括以上区域以外的9个县级单位。根据各区域的相似性和差异性,提出了各区域土地资源开发利用中存在的主要问题和未来发展方向。结果表明,基于主体功能区指标体系的土地利用分区对于指导区域土地开发和布局具有重要的实践意义。
英文摘要：
Land use zoning is an important aspect of comprehensive land use planning,and is also the embodiment and implementation of land use structure arrangement.The aim of this paper is to provide theoretical direction for land use and the future development of coastal region in Jiangsu Province.Considering the situation and characteristics of land us of coastal region in Jiangsu Province,according to the evaluation indicators of China＇s Main Functional Regions,this paper established evaluation indicator system for land use zoning through selecting three first class indicators（resource and environment carrying capacity,current exploiting density and development potential）and twelve second class indicators.Then systematic clustering analysis was made on the 20 administrative units of coastal region in Jiangsu Province by using SPSS.According to the practical situation and exploiting extent of the coastal region,it was divided into four sub-regions：Optimized development region,which includes Lianyungang Ciry,Nantong City and Yancheng City.Coastal potential region,which includes Rudong County,Dafeng City and Dongtai City.Important development region,which includes Haian County,Qidong County,Rugao County,Tongzhou City and Haimen City.General development region,includes other nine counties.At last,the main problems and future development direction in land use for each sub-regions were put forward according to the similarity and discrepancy among different regions.The results indicate that land use zoning based on evaluation indicators of China＇s Main Functional Regions are very important to regional land use practice and structure arrangement.
