摘　　要：根据复合生态系统耦合理论,借助能值理论及分析方法,对玛纳斯河流域—绿洲生态系统组成、结构、功能及MODS生态耦合的理论、方法及机制进行了理论构建,得出山地是生态耦合的"物流高地"、荒漠是生态耦合的"能流高地"、绿洲是生态耦合的"信息控制节点",而水资源及水文循环是决定耦合的关键因子,水资源能值的有效转换和系统控制决定着各类系统对MODS的贡献及MODS生态耦合的发生规律.According to the compound eco-systematic coupling theory, with the aid of the energy value theory and the analysis method, this article constructed the composition, structure and function of the Manas basin-oasis ecosystem, and also the theory, method and mechanism of its MODS ecologic coupling. We concluded that the mountainous region is the ＂high ground of ground of material flows＂ for ecologic coupling, deserts region is the ＂energy flow ＂ for ecologic coupling and the oasis is the ＂message control pitch point＂ for ecologic coupling, while the water resources and the circulation of water are the essential factors in deciding the coupling. So the effective transformation of water resources energy and the system control decide the contribution of each kind of system to the MODS and also decide the occurrence rule of the MODS ecological coupling.
