Study on Ecosystem Service Function Value Change in Xinjiang ABI Lake Area

This paper use three time intervals´ land use date of 1985, 1992 and 2005 in ABI lake area to estimate change in value of ecosystem services which arouse by changing of land use. It is proved that: cultivated land, forest land, pasture land, residential land, industrial and mineral land, water area had been considerably increased, only unused land had been decreased in 1980~1992; cultivated land, unused land and other land use types had been considerably increased, the rest of land use types had been decreased in 1992~2005; cultivated land, forest land, pasture land, residential land, industrial and mineral land and water area had been increased in 1985~2005, only unused land and the other land use types had been decreased. The ecosystem service value of ABI lake area separately were 0.14×10⁸ RMB, 0.20×10⁸ RMB, 0.19×10⁸ RMB in 1980, 1992, 2005, the ecosystem service value had been increased 0.06×10⁸RMB in 1985~1992, the ecosystem service value had been lost 0.01×10⁸RMB in 1992~2005, the ecosystem service value had been increased 0.05×10⁸RMB during the 25 years, the main reason was that 82.14% unused land had been transferred to cultivated land, forest land, grassland, water area.
