发达地区与欠发达地区耕地变化及其驱动因子比较研究——以江苏省江阴市和涟水县为例

Comparative Study on Changes of Cultivated Land and Their Driving Factors in Developed District and Underdeveloped District——Taking Example for Jiangyin City and Lianshui County in Jiangsu Province

利用江阴、涟水2000～2009年的土地利用数据及相关社会经济资料,从耕地数量变化入手,比较分析了两县市耕地动态变化的规律,并运用灰色关联度法定量研究了两者耕地数量变化的驱动机制,比较了发达地区与欠发达地区耕地变化驱动因子的异同,以期为因地制宜的耕地保护政策的制定提供科学依据。

By using land use data and relative economic and social references in Jiangyin city and Lianshui county during 2000~2009,the dynamic changing law of the cultivated land area was comparatively analyzed,the driving mechanism of the cultivated land area change was quantitatively researched by using grey related degree analysis,and then the difference in the driving factors of the cultivated land area change between developed district and underdeveloped district was compared,hoping to provide the scientific basis for the making of cultivated land protection policy based on the local conditions.
