Studies on the renovation and governance of urban villages have become the interest of human geography since the 1990s.However up to now,there is little literature focusing on the development patterns and dynamic mechanism of the spatial evolution of urban villages based on the theoretical system of urban spatial structure,and there are few scholars doing analyses on the relationship between urban villages and general urban areas in terms of spatial development.In this paper,Shenzhen,the most representative city of China in terms of urban village development,is taken as a case for exploring the characteristics and modes of the spatial evolution of urban villages.With census data of urban village construction in 1999 and 2004 in terms of built-up area,floor area,and construction intensity,the spatial and temporal evolution of the 91 administrative urban villages in the original Shenzhen Special Economic Zone have been analyzed in comparison with that of Shenzhen's general urban areas.It is indicated that the spatial evolution of urban villages matches with the general rules of the spatial development of general urban areas in three aspects.First,land expansion is the most remarkable mode of spatial evolution in the early stage of development;second,in the period of rapid development,there is the obvious tendency of "distance-decay" in terms of construction intensity accompanied by some anomalous fluctuations at certain points;third,renewal and redevelopment are carried out gradually in the mature stage of development.However,because of historical and institutional restrictions,the spatial evolution of urban villages shows its unique characteristics in the aspects of original spatial distribution and spatial expansion mode in the period of rapid development,etc.The outcomes of this study would help not only enrich the theoretical study on the evolution mode of urban spatial structure,but also strengthen the administration over urban villages,in particular with the suggestions that the spatial evolution of urban vil
