Abstract: Stability is one of the most important characteristics in ecosystem. Of many concepts of ecosystem stability, ecologists regard it as the definition of stability that the capability of ecosystem to resist disturbances and the capability of ecosystem to recover after disturbances. The theories or hypothesis of stability, such as diversity-stability theory, feedback theory, food web theory, redundancy theory, were presented. The common methods for the measurements of animal communities and plant communities were introduced. Such problems as the confusion of classifying stratification, the unrepresentative in dices, the lack of possibility for contrasting, etc. in the evaluation of ecosystem stability was pointed out. This paper also introduced the research methods of field ecological stability and mathematical ecological stability. The significant of study on stability in arid and semi-arid regions were specially emphasized and the tendency of ecosystem stability research was predicted.
