| 摘 要： | 耕地资源与城市化水平之间存在着密切的关系.以河南省所辖地区为研究单元,分别构建了耕地资源指数和城市化水平指数,采用主成分分析法对1990,1995,2000和2005年河南省各地区的耕地资源和城市化水平进行了数量化.然后利用协调度模型对4个年份各个地区的耕地资源与城市化水平协调度进行了定量分析,并划分出协调发展类型.结果表明,各年份耕地资源指数的区域分布特征基本一致,河南省城市化水平呈现出明显的上升现象.协调度的高低由两种指数的大小及其之间的差异决定,河南省耕地资源与城市化水平之间的协调度逐步上升.在研究前期,耕地资源与城市化水平失调的地区主要是传统的农业区;而在研究后期,两者失调的地区主要集中在工业基础较好、城市化水平较高的地区.

| Abstract: | There is a close relationship between arable resource and urbanization level. This paper takes all regions in He'nan Province as the research units,and separately constructs the indexes of arable land and urbanization level. Then the paper carries on the mathematical quantification for the arable land index and the urbanization level index of all regions in He'nan Province in 1990,1995,2000 and 2005,adopting principal component analysis. Using the coordinated model,the paper carries on the quantitative analysis for the indexes of arable land and urbanization level,and divides the types of coordinated development. The results show that the regional distribution of arable land index basically consistent in the four years. The entire province urbanization level presents the obvious rise phenomenon. The coordinated development degree is decided by the two indexes and the difference between of them. In the earlier research period,the traditional agriculture regions are usually imbalance between arable land and urbanization. But in the later research period,the regions are mainly imbalance where are in the good industry foundation and high urbanized level area. |
