Based on TM remote sensing image and topographic map, the spatial information of landscape pattern was extracted in study areas in 1990, 2000 and 2010. With the principles and methods of landscape ecology, land use/cover change, ecosystem service values were selected to construct the ecological safety index which was used to quantitatively analyze the dynamic changes of landscape pattern and elucidated ecological safety status in study area. Result showed that During the 20 years from 1990 to 2010, as human factors interference increase, the farmland and construction land increased by 21.11% and 15.38% respectively, the grassland area is reduced by 27.57%.Cropland had an increased trend during the period of 1990 to 2010 period, The wood land and swamp land had an increased trend during the period of 1990 to 2000 area also, but reduced during from 2000 to 2010.From 1990 to 2010, the whole study area lied in the level of relatively safer, but the safe area was reduced the amount of 4967 ha during 2000 to 2010. The relatively safer land areas was increased first then reduced during the whole study period, the relatively non-safer level land and relatively safer level land areas were accounting for 10.81% and 2.92% of the total area respectively.
