This paper took SPOT high-resolution remote sensing image as the main data source, and used GIS and mathematical statistics method to analyze Spatiotemporal changes of land use /cover change and its Correlation factor"before and after of the handover to China"(1993 - 2006 ).The construction sites, green spaces, water and unused land area of the circumstances surrounding the change had been mainly analyzed to find out changes in rules. Selected the social, economic factors related to land-use changes by correlation analysis and principal component to reveal the main driving factor of land-use change in the period of structural transformation before and after of the handover to China .It's typical and representative to make a study on Hong Kong's land use/change due to its status as a highly developed international metropolis. How to ensure its regional economic prosperity and friendly entironment, based on the limited land supply would make a reference for land resources'intensivism and economical use is an important theoretical value and practical significance.
