中文摘要：

随着社会经济的发展以及城市化进程的加快,部分耕地非农化已成必然,开展耕地集约利用研究,对缓解人地矛盾、保障社会经济可持续发展具有重要的意义。以江西省为例,从人地关系角度出发,构建基于PSR模型的耕地集约利用评价指标体系,运用熵值法、极差标准化方法及综合指数法,计算出1998～2007年江西省耕地利用集约度,得出在这期间江西省耕地集约利用水平及PSR各子系统协调度呈上升趋势;并通过SPSS软件采用主成分分析法,分析其耕地集约利用水平变化的驱动因素,主要概括为社会经济因素、耕作资源及政策制度因素、自然因素。研究结果可为江西省今后耕地集约利用提供一定的科学依据,也为其他省份提供一些参考价值。

英文摘要：

With the development of social economy and urbanization,partial cultivated land conversion has already become inevitable.Analysis on intensive cultivated land use has important significance for releasing human-land conflict and ensuring sustainable development of social economy.From the perspective of human-land relationship,this paper constructed evaluation index system for intensive cultivated land use based on PSR model,and used entropy method,maximum difference normalization method and comprehensive index method.Taking Jiangxi Province for an example,this paper calculated the intensive degree of cultivated land in Jiangxi Province from 1998to 2007,and obtained that the intensive degree and each PSR subsystem coordination degree showed an increasing trend.It also used SPSS software and principal components analysis to analyze the driving forces of intensive cultivated land use.The driving forces include population economy factor,farming resource factor,policy system factor and nature factor.Results could provide certain scientific basis for the intensive cultivated land use in Jiangxi Province and some reference value for other provinces.
