It is of significance to apply LUCC ecological environmental impact based on ESV to study the new land planning. In Rugao city, the dynamic changes or land utilization during 1997 to 2006 indicates that the big contributions to the land ecological system are waste disposal, water source maintenance, climatic adjustment, soil formation and protection, decreasing in contribution factors. The cause that the ESV fell from 2006 to 1997 is derived from a 〖JP3〗decrease in garden land, water fields, sand fields which are unused. This paper classifies the lands according to their ecological functions into three grades, important, secondary important and normal. MapGIS is applied to draw the ecological function map, offering a reference for the new land utilization planning and sustainable development in Rugao city.
