摘　　要：能值理论和方法,为研究MODS系统的生态耦合关系及耦合功能提供了系统理论和方法。提出:山地是MODS生态耦合的"物流高地",荒漠是MODS生态耦合的"能流高地",二者共同构成了MODS生态耦合的能值来源及其转换基础;绿洲是MODS耦合的"信息流高地",是耦合生态系统能量流动、物质转换、信息传递的节点和核心,控制着MODS生态耦合的能值转换效率及方向。通过生态能值分析初步得出了MODS生态耦合机理模型。From the view of genetic principle, inland river basin is composed of the mountain-oasis-desert system （MODS）. Competitive unification based on the process of the hydrologic cycle decides the scale and intension of the material cycle, energy flowing, and information transmission. The structure is the key to ensure the effective combination, efficient transformation, and high-quality feedback of material and energy in inland basin, to realize such structure-function body and advance its coupling and upgrading in the respects of time and space. So the three heterogeneous kinds of system＇s coupled effect will effectively give out the ecological potential energy of composite ecological system, and generate the better ecological coupled efficiency among society, economy and environment. Because the energy analysis theory and method can provide the systematic theory and method for the study on the ecologic coupling relations and coupling function of MODS, it will converse the different property＇s energy into the same quality, monitor comparability＇s energy, and make the various levels and kinds of energy calculation, contrast and analysis. It provides the theory framework and method system at the coupling level for evaluating the structure and function of system, exploring the implementing approach and behavior rules of the eco-economy. The article chooses the series of energy index to unify and quantitatively calculate the different kinds of ecological flow. It is concluded that mountain is the ＂material flow high area＂ while the desert is the ＂energy flow high area＂ of the MODS ecologic coupling. The oasis is the ＂Information flow high ground＂ of the MODS ecologic coupling, and is also the pitch point and core of the energy flow, material transformation and information transmission on MODS ecologic coupling, controlling the energy transfer efficiency and the direction of MODS ecology coupling and initially obtaining the MODS ecology coupling mechanism model through the ecology energy analysis.
