Abstract:: Based on the land use change information obtained from TM/ETM images in 1990, 2000, 2010 and 2015, using the method and mode about ecological value estimation, we analyzed the change rule of land use and its effects on the ecosystem service value in recent 25 years in Yulin City. The results showed that grassland, cultivated land, unused land and woodland were the main land use types, and the areas of grassland, woodland, building land presented the increasing tendency while cultivated land, unused area, water area decreased during 1990—2015. This changes, in particular decrease of water area and increase of building land, has caused the ecosystem services value to decrease, especial for the decrease of ecosystem services value of waste disposal, water conservation and food production, the ecosystem service value has decreased from 13 384 million to 13 235 million yuan, reduced by 149 million yuan in the study period. Water area is the key to protection of the ecological environment, therefore, with respect to the future land use, we must specially focus on protection of the water bodies.
