The system response and adaptation under disturbance is the basis and core in clarifying the study of ecosystem stability maintenance and steady-state transformation, and has significance theoretical guiding for the restoration of degraded ecosystem. In order to determine the response process of each component factor and the overall characteristics in different steady stages in the alpine Kobresia meadow degradation succession process, and discuss the mechanism in ecosystem stability maintenance under the interference condition, a series of investigations and experiments were carried out on core distribution region of the Alpine Kobresia Meadow in Qinghai, and the characteristics of plant communities, soil nutrient contents, soil biological crust and mattic epipedon as representative index were discussed in the research. The results showed constituents of plant-soil system in different steady stages of the alpine Kobresia meadow was asynchronous in response to degradation, and the asynchronous response effect resulted in the relative stability of the system characteristics in different platform periods and led the characteristics of system into the stabilization in degradation succession process. For example, plant functional groups maintained the overall characteristics of the ecosystem in stable by adjusting the proportion of components and structures of the plant community in the process of degeneration succession. While the component characteristics of plant-soil system maintained of the overall characteristics of plant community in different steady stages in dynamic balance through adjusting the characteristics of soil nutrient, soil-microbial crust and soil-surface in asynchronous feedback to degradation. In addition, the sensitivity of component factors could be changed in degradation steady stages, and the non-sensitive component factors in eco-system could be gradually replaced to the sensitive component factors with the degree of degradation deepens, which was the main reason for steady-state transformation. Therefore, alpine Kobresia meadow maintained stabilization through the asynchronous responses and negative feedback effects of different component factors to degradation, and the negative feedback factors were the core to maintain the stability of the system in alpine Kobresia degradation process. However, when the disturbance exceeded the threshold range of non-sensitive factors of plant-soil system in degradation process, the non-sensitive factors could also be transformed into sensitivity factors, resulting in the transformation of ecosystem out-of-balance, resulting the meadow undergo steady-state transformation. Therefore, the factors with negative feedback effect in the degradation were the key to maintain the ecosystem in stabilization, and the reduction the number of negative feedback effect factors is easy to increase the risk of steady-state transformation in the ecosystem.
