摘要
运用灰色关联分析结合主成分分析的方法,对无锡市1998～2009年耕地数量变化的人文驱动力因素进行了分析,并采用多元线性回归方法拟合得到无锡市耕地数量变化的人文驱动力模型。结果表明:无锡市耕地数量变化的主要人文驱动力是人口增长、农业经济发展及农业科技水平,并从这3个方面出发,对无锡市耕地资源保护提出了一些相应的建议。
The human driving force on the quantitative changes of the cultivated land in Wuxi city from 1998 to 2009 was analyzed by using gray relational analysis method and principal component analysis,and the corresponding model was constructed by using multiple linear regression method.The results indicated that the main human driving forces on the quantitative changes of the cultivated land in Wuxi city were population increase,agricultural economic development and agricultural science technology level.From these three aspects,this article brought forward some relevant suggestions for protecting the cultivated land resources in Wuxi city.
