Based on the backgrounds of the lack of rational evaluation due to the constraint of data and methods, and of a series problems of regional sustainable development caused by urban expansion of rapid urbanization in current research of urban expansion at home and abroad, this paper attempted to build a bridge from the pathology of non-coordinated development to coordinated development from the perspective of reverse thinking and problem diagnosis, and then constructed a reasonable evaluation index system of urban space from the perspective of non-coordination. Specific characterization was the three levels, i.e. non-coordination of the total control of urban construction land, non-coordination of ratio nonconforming structure in urban construction land and agricultural land, ecological land, as well as the non-coordination of space allocation in established urban construction land. On the basis of these, an empirical analysis in 246 prefecture-level cities of China in 2008 was made. By partitioning (economic division) and classification (administrative level, road transport, urban scale, urban properties, weather conditions, terrain conditions, etc.), its inherent regularity was revealed, summarized and aggregated. Results showed that the identification system was reasonable and the results coincided with reality, which could serve as the theoretical basis for the basic national conditions where there are conflicts between manland relationships, for the promotion of intensive, efficient and rational use of land resources and for sustainable development among inter-districts.
