The alpine grassland is the main pasture on the Qinghai-Tibetan Plateau,with the worst climatic environment to plant communities and a long history of livestock grazing.In the recent years,the alpine grasslands have been disturbed due to overgrazing and climate change,which damaged the function of ecosystem,influenced soil nutrients,water conservation and threatened the living condition of the herdsmen.Mini-patches are the basic material for carrying out research on the structural characteristics of ecosystems,the function of components of ecosystems,and the organizational pattern of alpine grassland.Meanwhile it provides useful tool in understanding the mechanisms of ecosystem succession and stability.In this article we used mini-patches as tool to understand the succession process of alpine grassland ecosystem,organizational pattern and mechanisms of ecosystems for maintaining stability.It would provide guidelines on understanding the processes and mechanisms of the alpine grassland associated with degradation process.More researches would be required using mini-patch as a tool on the assessment of ecosystem health and the restoration of damaged ecosystems.
