摘要
文章依托县域范围内的农户调查资料和统计资料,利用资料分析、相关分析、主成分分析等方法研究了通城县近20多年来耕地利用集约度变化及其驱动机制。结果表明:耕地利用复种指数有所降低;以货币额表示的集约度有所增加。这主要是经济增长、科技进步的推力和人口增长、耕地面积减少的压力的结果,而并非农民内生的动力的结果。
Relying on information from famers and data from government, using information analysis, correlation analysis, principal components, this paper studied the change of intensity degree of arable land use and its driving mechanism. The results are repetition planting index of arable land use decreased, and intensity degree expressing by money increased in Tongcheng County during 1985 to 2006. This is the result of the thrust of economy increasing, science and technology advancing, the pressure of population increasing and arable land area decreasing, but not the result of farmers＇ fresh power.
