| Abstract: |
| This research used the remote sensing phantom data of 1989, 2001 and 2007 in the delta oasis of the Weigan and Kuqa Rivers, and analyzed the change of ecosystem service function value and the ecosystem sensitivity in research area during 1989 to 2007. The results showed:In the entire research time, the ecosystem service total value of the research area assumed a declining trend, and the distinction drop was from 1989’s 115.49×108 Yuan to 2001’s 106.83×108 Yuan and 2007’s 94.47×108 Yuan; In the ecosystem’s various single item service function value, various siingle item’s service function difference is remarkable, the ecologyy service function overall assumed a declining trend; For 18 years, the water source self-control function flaw was the most obvious, the service value reduced by 4.64×108Yuan, but food production function change was the smallest, its value growth was only 0.60×108 Yuan; At the same time, through various single item’s service function in each research stage’s value change situation, the increased range of food production function ecology service value was obvious, the water source self-control function value dropped obviously, and the entertaiinment culture function’s value change was the smallest; Through the ecosystem sensitivity index analysis, it is discovered that various landscapes’ ecoysttem sensitivity index iis smaller than 1, which suggests that the total ecosystem service value to the ecological value coefficient of the research area is insensitive and lacks elasticity. |
