Abstract: The paper selects Baoji city as a research area, sets up the assessment index system, index assessment standards and the evaluation models to assess human-water harmony degree. To begin with the concept of human-water harmony, the authors establish a set of indicators with capacity to evaluate human-water harmony. Employing the opposites and unity variable fuzzy set theory and cooperation game theory, a variable fuzzy set model based on cooperation game weight is established to describe comprehensive development degree of human-water system. The coordination exponent model describes the mutual coordination relationship of water system and human system. Then the information entropy coordination degree model is proposed to assess the coordination degree of complex human-water system. Based on the data of comprehensive development degree and coordination degree of complex human-water system, the paper derives harmony degree assessment model. The proposed models are applied to assess the human-water harmony degree from the year 2001 to 2010 in Baoji city, and the lowest harmony degree value is 0.631 in 2002 and the highest harmony degree value is 0.833 in 2009. In general, the harmony degree shows a slow increasing trend in the past 10 years, which indicates water system and human system in Baoji city is becoming more and more harmonious. Assessment results are similar by comparing with the results from the fuzzy matter-element evaluation model, and the results show that the harmony degrees are in grade Ⅱ, Ⅲ and Ⅴ, which confirm the feasibility of the models and reliability of results. It also indicates that the research on the evaluation index system and models in this paper provides a practicable and operable method for assessing human-water harmony.

Key words: human-water harmony evaluation, complex human-water system, harmony degree, coordination degree
