By methods of cluster analysis and grey rational analysis, degree of harmony was categorized and calculated. Results revealed that harmony degree of different cities had certain gaps which were continually widening and can be divided into four categories. Relative scores on harmony of them are almost consistency with the category. It is found that the difference on land use put significant on the degree of harmony.
