摘要
根据张家界市永定区1989-2005年耕地资源及人均GDP的统计资料,分析了永定区耕地面积与经济发展的动态变化过程,建立了耕地减少量与人均GDP数据的定量相关模型,从而得出了该地区耕地面积减少与经济发展间的关系规律。研究结果表明,永定区耕地面积减少量最初随着人均GDP的增加而增加,当越过一个阈值后(2002年),就开始随着人均GDP的增长而降低。虽然这样的演化规律受当地的自然条件及其他相关因素的影响而有所波动,出现阶段性变化,但基本上仍吻合库兹尼茨曲线的一般特征。结合当前实际,对湘西北喀斯特地区如何实现经济增长与耕地保护的协调发展提出了相应的措施和建议。
According to the statistical data of arable land and those of per-capita GDP in Yongding county of Zhangjiajie from 1996-2005, change course of arable land and economic growth were analyzed in this paper. Then the general rules delineating the relationship between arable land decrease and economic growth was explored by setting up relevant models of per-capita GDP and arable land decrease. The results indicated that the arable land decrease increased with the increment of per-capita GDP from the beginning, and then the situation was reversed af- ter the time reached a certain threshold(2002) ,which is, in general, consistent with the characteristics of Kuznets Curve, even though this curve was distorted by natural condition and other factors in Yongding county. At last, the paper proposes some measures and suggestions about how to realize the sustainable development of economy and arable land protection in karst mountain areas of northwestern Hunnan.
