In the rapid urbanization of China, the phenomenon of urban sprawl is becoming more and more obvious. Firstly, this paper introduces the basic concept and characteristics of Western urban sprawl. Then it explains the difference of urban sprawl between Occident and China, which is closely linked with economic and social development. So it establishes an urban sprawl evaluation system with AHP on the basis of western experiences and approaches from the traditional perspective of spatial pattern. Then the coordinating degree between economy and society is used to amend the evaluation system. In order to get the value of the coordinating degree, a synthesized index system of economy and society which contains 10 indexes is built. In addition, the method of principal component analysis and fuzzy math is applied in the assessment process. In order to demonstrate the whole evaluation system, the data of Hangzhou city are used to conduct an actual assessment and analysis. The result indicates that the degree of urban sprawl is relatively great, which is accordant with the judgement from the spatial form of Hangzhou. Based on the result, we discuss the control mechanism of urban sprawl and some proposals are put forward from many aspects.

Key words: urban sprawl, evaluation system, control method, Hangzhou cit
