Abstract
With regard to the decision-making issue of uncertain multiattribute of lake eutrophication evaluation, set pair analysis model was proposed based on combination of interval number and triangular fuzzy number, and simple correlation functions were introduced for index weight determination. In this paper, basic principles of the lake eutrophication evaluation and description method of converting interval number and triangular fuzzy number into the connection number of set pair analysis were introduced in detail. The modulus of connection number and the identical degrees of attribute level modulus and attribute value modulus were first calculated. Then, through referring to the attribute level n and their degrees of identity, n-element connection number was established. Afterwards, mapping relation between degree and connection number was set up to identify the evaluation level. This model was applied to evaluate the eutrophication status of 9 lakes in China and the evaluation results were consistent with the actual situation, providing a scientific basis for control and protection of lake eutrophication.关键词
