汉中耕地面积变化与城市化发展相关分析

研究了近56年来汉中地区耕地面积动态变化情况及其城市化进程,并对二者关系进行了计量分析。结果显示:56年来汉中耕地面积变化总体呈下降趋势,与全省的耕地面积变化规律基本一致,城市化发展经历了停滞不前和稳步攀升两个阶段;人口增长与耕地面积减少量之间存在着明显的类似库兹涅茨曲线倒"U"型关系,城市化水平与耕地面积减少量之间存在正"U"型关系。提出在加快城市化进程的同时,应该采取法律、行政、经济、技术等手段缓和库兹涅茨曲线的曲度,最大程度实现保护耕地的目标。图5,参17。

Analysis of Correlation Between the Change of Cultivated Land and Urbanization Development in Hanzhong

This paper studies the dynamic change of cultivated land and urbanization course in Hanzhong area during the past 56 years,then gives us a calculated analysis of their correlation.The results show that the dynamic change of cultivated land presents a collectivity downtrend,which is consistent with provincial rule.And urbanization development experiences two steps,those are stagnancy step and steadily ascending step.The cultivated land decrease with population increasing shows an obvious relationship the same to inversed U of Kuznets Curve.Also the relation between urbanization level and decrement of cultivated land area is same to positive U of Kuznets Curve.It suggests that we should achieve the aim of protecting cultivated land as possible as we can through ways like law,administration,economy,technique and so on.
