Abstract: With the aid of the technology of analytic hierarchy process and fuzzy pattern recognition,a comprehensive evaluation model is established and used to analyze ecological resilience and ecological load of forest,grassland and farmland ecosystems exposed to the strongest human interference in the Qilian Mountain Nature Reserve,and then of the reserve as a whole.Results show that the Qilian Mountain ecosystem has suffered strong human interference and has been exposed to ecological overload.But within the ecosystem,discrepancies do exist between subsystems in spatial distribution of ecological load.The subsystems of forest and grassland are seriously overloaded while that of farmland is medium overloaded.In terms of spatial distribution of ecological load,the northwest region is more heavier than the southeast;whereas in terms of overloading of subsystems,the subsystems of forest and grassland are less in the southeast than in the northwest,but the subsystem of farmland is more in the southeast than in the northwest.

Key words: ecological resilience, Qilian Mountain； Nature Reserve, analytic hierarchy process, fuzzy pattern recognition
