### Abstract

Regional ecological security assessment can be attained by assessing model, the establishment of which has to overcome theoretical, technological, methodological, data difficulties.According to the essential characteristics of ecosystem, the paper optimally compounds the comprehensive models of regional ecological security assessment such as hierarchical analysis, gray system, fuzzy mathematics, variable weight, etc., thus a-chieving the assessing conclusions which closely reflects the real situations.In this paper, the composite models of hierarchical analysis-variable weight-fuzzy-gray correlation are constructed and used as the assessing model for regional ecological security.The case study here shows that this model is the relative best one for regional ecological security assessment at the current stage and conditions.
