| 摘 要： | In this paper, the concepts and principles of mountain-oasis-desert system (MODS) are put forward according to the natural geographical situations in arid zone of western china. The spatiotemporal characteristics and dynamic changes of typical MODS, the process of material circulation, energy transform and information transmission among MODS and the mechanism of MODS interaction and symbiosis are analyzed. The foundation and frame of the coupling type are determined by landform types and climate characteristics: the spatial pattern of the coupling type is determined by the hydrological characteristics; the vegetation type reflects the appearance of the coupling type; the soil state restricts the function of the coupling type and the human activities influence the development course of the coupling type. Interface course of MODS is closely related to such medium as water, soil, air, etc., and water is the major medium during the course of material circulation, energy transform and information transmission. The disorder of water salt, water heat and water land restricts the stability of water ecosystem.

The disorder of water salt, water heat and water land restricts the stability of water ecosystem. |
