The interior structure of vulnerable ecological regions is instable and these regions are hypersensitive to the exterior disturbances.Actually,their development trends and stability are the inherent forms of vulnerable ecological regions' basic properties.Therefore,the assessment of vulnerable ecological regions should include three parts:assessment of status quo,assessment of development trend and assessment of stability.Base d on new concept of vulnerable ecological re-gions,this paper assesses the status quo by fuzzy theory and predicts its develop ment trend by grey theory.Non-linear theories are applied to assess stabilities of vulnerable eco logical regions for the first time and the effect is very well.
