| 摘 要： | 玛纳斯河为天山北麓准噶尔盆地最大的内陆河,玛纳斯河流域生态系统独特,且具有干旱区生态系统的特点。近50年来,玛纳斯河流域由于受到人类活动的影响,生态系统稳定性发生了很大变化。通过运用生态学和系统学理论,使用AHP法对玛纳斯河流域生态系统稳定性进行了研究,确立了玛纳斯河流域生态系统稳定性评价指标体系,使用多个指标对流域生态系统进行了指标权重评定,通过计算认为玛纳斯河流域生态系统目前较为稳定。

Research on ecosystem stability in Manas River Valley |
| |
| Abstract: | Manas River valley is the widest one in Junggar Basin,and its ecosystem is composed of two types of subsystems: mountain ecosystem and plain-desert-oasis ecosystem,both of which include several different ecosystems.In recent 50 years,its evolution had four models: natural oasis→man-made oasis,desert→man-made oasis,natural oasis→desert,man-made oasis→desert.This research took the Manas river valley as an example,use AHP method that has 3 layers and 26 indexes to obtain the ending index weight by the specialists' scoring and our computing.It did the evaluation using the present data in Manas River valley and arrived at the conclusion that Manas river valley is stable basically.The forming reasons were analyzed,and some correlated suggestions for this river valley were given in the end. |
