摘　　要：耕地集约利用关乎国家粮食安全及可持续发展问题。本文以河南省地级市为研究区域,运用多因素综合评价法和GIS手段,定量分析了1989-2008年河南省各个地级市耕地集约利用水平及时空分布变化,并在此基础上,采用主成分分析法,重点分析了影响耕地集约利用的驱动力因素。研究结果表明:1989-2008年间河南省耕地集约利用水平总体上显著提高;省域范围内耕地集约利用水平空间差异显著;人口因素、社会经济因素、农业科技因素、自然因素、政策因素对河南省耕地集约利用水平产生一定的影响,其中农业科技进步因素是影响河南省耕地集约利用水平最重要的驱动因子。此评价结果与现实情况基本一致,具有一定的可行性。Intensive use of cultivated land is related to national food security and sustainable development. The paper takes cities as evaluation units to quantitatively analyze the spatial-temporal variance features of the arable land intensity and its driving forces from 1989 to 2008 in Henan Province. Methods of comprehensive evaluation, principal component analysis and GIS spatial analysis were employed. The results indicated that from 1989 to 2008 the intensive use level of cultivated land in Henan Province had been fluctuating up. The intensive use level of cultivated land took on obvious territorial differences in provincial domain-wide. The driving forces influencing the intensive cultivated land use in Henan Province are population factors, socioeconomic factors, agricultural science and technology factors, natural factors and policy factors, in which agricultural science and technology factors are the main driving forces. The results of evaluation were consistent with the realities and had certain feasibilities.
