基于PSR模型的江苏省国家级开发区土地集约利用评价分析

将"压力-状态-响应"(PSR)模型引入到开发区土地集约利用评价指标体系中,采用主成份分析方法,对江苏省20个国家级开发区土地集约利用水平进行评价分析。研究结果表明,PSR模型评价指标体系及主成份分析方法,能较好地适应开发区土地集约利用评价的需要;江苏省国家级开发区主要受土地资源条件、土地利用程度、用地结构状况及经济效益影响,开发区所在母城经济状况及区位条件也是影响土地集约利用的因素;开发区土地集约利用不仅要注重提高土地利用的产出效益,还要特别重视土地使用面临的压力和反馈能力的建设。

Evaluaion and Analysis on the Land Intensive Use of National Development Zones of Jiangsu Province Based on the PSR Model

The "pressure-state-response"(PSR) model was introduced to the evaluation index system of land intensive use of development zones,and then the land intensive utilization level of twenty national development zones in Jiangsu Province was assessed by principal component analysis.As indicated by the results,the PSR model and PCA method well met the needs for evaluating the land intensive use of development zones.The land intensive use of national development zone in Jiangsu Province is affected by the land resources,land utilization degree,land use structure status and economic benefit of the development zone,as well as the economy and geographic conditions of the mother city.The land intensive use of development zones should pay attention to not only improving the output of the land use efficiency,but also the pressure and feedback ability of lands.
