中文摘要：

城市开发区土地集约利用潜力研究对于城市发展、城市规划将具有重要的理论和现实意义。选取23个与城市开发区土地集约利用潜力相关的指标，构建了城市开发区土地集约利用评价指标体系，包括土地投入、土地产出、土地利用结构和可持续利用度4个方面，通过聚类分析和主成分分析方法以江苏省18个典型城市开发区调查数据为例，对城市开发区土地集约利用潜力进行评价。研究结果认为，城市开发区土地集约利用潜力可以分为4个层次：①超集约，即土地供求紧张，分值大于0．3；②集约。土地供求平衡，分值在0～0.3之间；③基本集约，土地供求在一定时期内平衡．分值在-0．3—0之间；④欠集约，土地有所闲置，土地产出率较低，分值小于-0．3。城市开发区土地集约利用潜力区域差异：苏南地区水平高于苏中和苏北地区，而苏中地区高于苏北地区。据此，提出提高土地集约水平相关政策建议。

英文摘要：

The degree of intensive land use is of great significance for urban development zones. Especially in Jiangsu Province where cultivated land resource pressures resulted from urbanization is even more significant. This paper chooses 23 indicators relating to assessment of intensive land use potential and 18 urban development zones in Jiangsu Province as study areas to conduct evaluation of intensive degree of land use. Component analysis and systematic cluster analysis were adopted to analyze the 23 indicators. The indicators were divided into four categories ： 1 ） Land use structure ; 2） the level of inputs including land, capital and labor force; 3） efficiency of land outputs; 4）the level of land sustainable use. The results indicates that the F1～ F7 principal components generally take 85. 016% of information of the whole. In terms of the general score F of the 17 principal components, the results were used to sort out the rank of urban development zones. The intensive degree of land use has four grades ： 1 ） Super intensive level： namely the land supply is in severe shortage, index value over 0.3; 2） Intensive level： the land supply and demand is in equilibrium, index value at 0～ 0.3 ; 3） Inferior intensive level ： the land supply and demand is in equilibrium in certain period, index value at - 0.3 ～0; 4） Less intensive level： the idle land exist, index value lover than - 0.3. The intensive degree of land use varies in different regions of Jiangsu Province. The intensive degrees of land use in urban development zones in the south of the province are higher than that in other regions. Development zone in Southern Jiangsu Province is more developed than that in middle and northem Jiangsu Province.
