Abstract: The impact of urbanization on regional landscape is increasingly significant. How to harmonize the relationship between land exploitation and ecological protection becomes one of the most important and fundamental issues. Based on RS and GIS techniques, this paper studied the dynamic changes of landscape structure and pattern in the rapidly urbanized area, Xianlin New Town, of Nanjing. Significant changes of landscape structure had occurred in the study area from 2003 to 2009. The predominant landscape had gradually transformed from semi-natural landscape to man-made landscape. Cultivated land was dramatically impacted by human activities, and 556% of it was lost. The number of pond also reduced a lot, with a loss of 56.4%. The area of urban construction land was increased by 7.1% annually. With the rapid change in landscape structure, the landscape pattern also changed. The index of landscape diversity increased from 138 to 168, evenness index increased from 060 to 073, and connectivity index varied from 015 to 032.
