Abstract:: Global environmental changes, including land use and land cover changes, have considerable impacts on the ecological properties of ecosystems and therefore on the ecosystem services that societies derive from them. The study on ecosystem services value (ESV) has been one of the hottest issues in the field of ecology. Quantitative losses estimation on ESV of land use change will be a scientific basis for effective compensation of ecological resources use, and sustainable use of natural ecosystem. The information of land use change was extracted and analyzed during the past 16 years based on RS and GIS. The unit coefficient table of ESV was amended based on reference to the ESV coefficient by Xiegaodi and Costanza et al. , which combined with the actual situation in Chengdu city. The equivalent of ESV by per unit area was enacted in Chengdu city, and the loss estimation on ESV of land use change was quantitatively estimated. The result shows that the spatial and temporal pattern of land use has changed greatly in study area from 1992 to 2008.Land use change has led to ESV increase and obvious change in regions difference and EVS flow direction. The ecosystem structure is simple main sustained by the ecosystem of forestland, waterbody and land for agriculture et al. The ESV in study area increased from 35.429×10⁸ RMB yuan in 1992 to 38.833×10⁸ RMB yuan in 2008, the ESV had increased by 3.403×10⁸ yuan and the percentage of ESV had increased by 9.605%. The ESV increased 40.705×10⁸ yuan during 1992-2008 by 1.872×10⁸ yuan and change rate is 4.821%. There is a huge ESV difference in different land use types, the propotion of ESV for forest land in total VES is 59.684%, 70.929% and 67.125% in 1992, 2000 and 2008, respectively, the second place was water body and cultivated land;land use types conversion in 1992-2008 has led to change of ESV flow direction, cultivated land, the conversion of forest land and water body has the negative flow direction of VES. So, keeping economy development and environment quality to improve by the means of strictly controled the conversion from land for agoriculture land to built-land in the process of land use and then increase efficiency of built-land was enhanced. We conclude that future land use policy formulation should be given precedence to the conservation of these ecosystems, and further land use should be based on rigorous environmental impact analyses. Therefore, ecosystem such as cultivated land, forest land and water body is intense safe guarded in the course of future ecosystem management.
