城乡结合部耕地资源演变机理及驱动力分析--以武汉市黄陂区为例

耕地变化是区域土地利用变化的核心，其变化和流向反映了区域社会经济发展的基本态势。利用武汉市黄陂区的统计资料，对地处城乡结合部的黄陂区50多年来的耕地数量变化的时空特征进行分析研究，并用相关分析法和主成分分析法对黄陂区近20年耕地资源变化的驱动力因子进行了定量研究。结果表明，地处城乡结合部的黄陂区耕地资源的变化主要是受社会经济的快速发展、人口增长、农业结构调整及耕地比较效益的影响，为合理利用和保护耕地资源提供了参考。

An Analysis of Change and Driving Force of Cultivated Land in Urban Fringe--Taking Huangpi Area as an Example

Change of cultivated land is the core of land use change. The changing trend reflects the basic state of the regional society and economy. Based on the statistical data from Huangpi Area, Wuhan City, this paper analyses the spatial-temporal change of cultivated land and driving force using relevant analysis, principal component analysis and regression analysis, with the result that the cultivated land is reduced in the fringe of Wuhan City and the cultivated land of the south is reduced faster than that of the north, meanwhile the growth of population and economic development are the main factors for change of cultivated land.
