| 摘 要： | 分析了安徽省1978-2005年的耕地数量动态变化,并根据耕地数量变化的驱动机制选取了12个基础指标,采用主成分分析法定量分析了各指标间的相关性.同时提取两组主成分,对各主成分中指标因子的载荷矩阵进行了分析.结果表明,自改革开放以来,影响耕地数量变化的主要因素是人口增加、社会经济发展和产业结构调整.

| Abstract: | Analyzed the quantity dynamic changes of cultivated land in Anhui Province from 1978 to 2005.According to the driving mechanism of the quantity changes of cultivated land,selected 12 basic indicators.Method of component analysis was used in which the correlation of indicators were analyzed and two components were abstracted to analyze the indicatormatrix.The main conclusion were shown :since "open policy",the major factors influencing the quantity of cultivated land are Population growth,Socio-economic development and the adjustment of industrial strucyure. |
