通过建立耕地集约利用评价模型和采用灰色关联分析与多元回归分析方法,对河南省耕地集约利用时空分异及其驱动因素进行了分析.结果表明河南省耕地集约利用水平自2000年以来呈不断增长趋势,省域范围内耕地集约利用差异较大,差异原因主要是由于区域农业投入产出差异所致;政策、政府、农民和科技是河南省耕地集约利用水平的主要驱动力;农业从业人口与耕地集约利用呈负相关关系,主要是科技水平和农业机械化水平的提高,大批农业劳动力被解放出来的原因.图1,表5,参7.

Base on the model of cultivated land intensive use evaluation,this paper analyzes spatial-temporal variance of cultivated land intensive use and driving force factors in He' nan Province with Grey Incidence and multiple linear regression. Results indicate that the cultivated land intensive use presents iron,easing trend and obvious difference in regions of He' nan since 2000. And the reason of the difference is the diversity of investment and output. Policy,government,farmers,science and technology are the main driving force factors. The negative correlation was found between rural population engaged in agriculture and cultivated land intensive use, and the reason for this is that with the improving of technology and mechanization of agriculture, a large numbers of rural population are released from agriculture.
