| 本研究利用渭干河—库车河三角洲绿洲1989年、2001年和2007年的遥感影像数据，分析了1989~2007年间研究区生态系统服务功能价值变化和生态系统敏感性。结果发现：在整个研究期内，研究区生态系统服务总价值呈下降趋势，从1989年的115.49×108元，分别下降为2001年的106.83×108元和2007年的94.47×108元；在生态系统各单项服务功能价值中，各单项服务功能差异显著，生态服务功能总体呈下降趋势。18 a来，水源涵养功能缺失最为明显，服务价值减少了4.64×108元，而食物生产功能变化最小，其价值增长仅为0.60×108元；同时，通过各单项服务功能在各研究阶段的价值变化情况来看，食物生产功能的生态服务价值增幅明显，水源涵养功能价值下降显著，而娱乐文化功能的价值变化最小；通过对生态系统敏感性指数分析，发现各景观生态系统敏感性指数都小于1，说明研究区生态系统服务总价值对生态价值系数是不敏感的，缺乏弹性。 |

| 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. |
