绿洲稳定性研究的几个基本理论问题

目的 探讨绿洲稳定性的尺度、内涵和机理。方法 在回顾绿洲稳定性研究的基础上，主要采用系统论研究方法，从尺度入手，寻求解决问题的途径。结果 指出绿洲稳定性是具体尺度下的相对概念，提出绿洲稳定性的多维多层尺度类型体系、尺度间相互转化关系，以生态系统、绿洲复合系统、绿洲山盆系统、区域为尺度，多层次分析回答了绿洲稳定的概念、内涵、作用机理等基本问题。结论 系统理论是揭示干旱区背景下多作用力绿洲稳定性的基本途径；绿洲不稳定的实质是人地关系不协调，稳定的实质是可持续发展；实现绿洲的稳定良性演替，必须通过对复合系统两大驱动力关系进行优化和调控，以寻求自然与人的耦合。

Several basic academic problems of oasis stability

AimDiscussing on the basic academic standpoints on the stability of oasis such as the scale, intention and mechanism of oasis stability.MethodsSystematology theory and method.ResultsThe conception of oasis stability is relative one under some concrete scale. The oasis stability should include many dimension and hierarchy scales. The different conception, intention and mechanism of oasis stability are under the scales such as ecosystem, oasis multiplexed ecosystem and arid land MODS (Mountain-Oasis-Desert System).ConclusionsSystematology is the basic pathway of oasis stability, for which the driving-force is multiple and the background region is arid. The substance of oasis instability is disharmonious man-land relation and the substance of oasis stability is sustainable development. The actualizing way of oasis benignant transmutation is coupling, through which the two driving-forces (nature and manpower) of the oasis system got accommodated.
