The theory and method of evaluating city land intensive improve greatly in the homogeneous areas, based on it the evaluation of city land intensive allover the country was conducted. Because of the differences among cities, this evaluation was based on city classification. In the process of evaluation, firstly, the indicators of city classification and intensive land use were collected, which mainly included city construction land and relative social-economic data. Secondly, the method of hierarchical classification was adopted to divide 282 cities into 3 kinds, the first was mainly capital cities and vice-province cities; the second was mostly eastern coastal cities and some middle cities; the third was western cities and part of middle cities. Thirdly, principle component analysis was taken to get the numbers of principle component, dedicative ratios of each principle component, and indicator values of each kind of cities, then, the differences of numbers of principle component, dedicative ratios of each principle component, and indicator values of each kind was investigated. Lastly, the intensive values of each kind city was calculated, and then, the grade of each city was determined.
