The water resource plays an important role in the sustainable development of this system. The value of water conserved by the forest is influenced by natural, economic and social factors. In this paper, the water quality, per capita water resources, per capita GDP and population density are chosen as indices to construct an index system for a comprehensive evaluation of water resources value. The weights of these indices are 0.443, 0.31, 0.141 and 0.106 respectively, which are determined by the analytic hierarchy process(AHP) method. The water resources value has been assessed by the fuzzy comprehensive evaluation model. The results show that the water resources value in the Hani Rice Terraces System is 4.25 RMB/m^3. Evaluating the value of water resources in the Hani Rice Terraces System can provide a reference for ecological compensation, for raising public awareness of the importance of protecting the system, and ultimately achieving its sustainable development.展开更多

The traditional corporation valuation methods don not work well when encountering these types of corporations. Just in these backgrounds, a new method called CVBC model is brought forward to evaluate these types of corporations in our article, which is based on the customer lifetime value. In essence, it extends the concept of customer lifetime value and combined with the traditional financial methods, then creates a new valuation method. It can work well to the corporations, which have been said before. The principle, mathematical model of the method and the effect of the practical application are discussed in detail.展开更多
