唐山市耕地资源与城市化进程的关系

Correlation between Arable Land Resource and Urbanization Level in Tangshan City

采用唐山市1978-2007年的耕地面积数据,分析唐山市耕地面积变化及城市化发展过程,构建了耕地资源与城市化水平的回归模型。并借鉴经济与环境协调度模型,计算了耕地资源与城市化水平的协调度。结果表明,唐山市耕地资源与城市化水平之间存在极强的负相关关系,随着城市化水平的提高,耕地面积逐年减少;多数年份耕地资源与城市化水平协调度呈调和状态,耕地资源总体保持在承载力范围内,短期内尚能接受。

The arable land area data of Tangshan city from 1978 to 2007 were used to analyze its change of arable land area and urbanization development process and to construct the regression mode between land resource and urbanization level.
