Study On Urban Spatial Expansion Of Wenzhou City In The Period Of Rapid Urbanization

According to researches, China’s urbanization has entered the stage of rabid development since1992. As the typical city in the developed area of China, Wenzhou’s urban space is expanding rabidly and the scale of land use of cities is enlarging continuously in the stage of rapid urbanization process. Many urban problems thus come into being, so it’s necessary to study the urban spatial expansion of Wenzhou in the stage of rapid urbanization.This paper firstly explains the related theories and the impact factors of urban spatial expansion, which serves as the theoretical foundation of the practice research. In the process of conducting case study on the urban spatial expansion of Wenzhou, the paper summarizes the urban development process of Wenzhou in the historical period systematically and finds that although Wenzhou has experienced several ups and downs, its urban space still lies within the scope of ancient city and the spatial expansion is limited. Then, it analyses the spatial expansion process of Wenzhou since the initiation of the rapid urbanization, measures the changes of the scale and strength of spatial expansion with the quantitative method to explore the spatial-temporal characteristics and regular patterns of urban spatial expansion of Wenzhou and points out the problems of the disappearance of the characteristics of ancient city and the traffic jam in the present urban development of Wenzhou. At last, it makes use of the grey relational analysis and principal component analysis to analyze the factors affecting the spatial expansion, compares the impact factors of the urban spatial expansion of Wenzhou quantitatively and analyzes the mechanism affecting the urban spatial expansion of Wenzhou form the aspects of physic-geographical environment, economic development, population growth, traffic construction and policy.Through investigation in practical experiences in foreign countries combined with current situation of Wenzhou city, we propose the urban spatial expansion strategy for Wenzhou city, in order to provide reference for future sustainable development of Wenzhou city.
