摘要：

An improved membership fuzzy matter-element evaluation modeling based on the cooperative game weight is proposed in this study. The assessment of eco-environmental quality is a complex fuzzy issue. In order to solve fuzzy boundary problems efficiently, the applicable conditions of the membership function in boundary layers have been modified. Employing the cooperative game theory, an improved membership fuzzy matter-element assessment model based on the cooperative game weight is put forward in this study (IFME-CGW). The derived model is applied to assess eco-environmental quality in Shiyang River basin in Gansu province. The results are reasonable and satisfactory by comparing to other methods. The study of this practical example shows that the IFME-CGW model proposed is a feasible way to solve the fuzzy boundary issue with simple algorithm and strong practicability. It also indicates that the IFME-CGW model can provide a practical and feasible method for assessing eco-environmental quality in arid area.
