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.
