摘要
水资源价值在水资源持续利用中具有重要的地位,现有的影子价格模型、边际机会成本模型、供求价格模型等水资源价值模型各有优缺点,但均没有完全解决水资源价值问题。水资源价值系统是由社会、经济、环境相互作用形成的复合系统,具有模糊性和复杂性。为此,本文提出了水资源价值模糊数学模型,该模型由水资源价值综合评价(Ⅰ)和水资源价值(价格)计算(Ⅱ)两部分组成,其中Ⅰ部分是对影响水资源价值的各因素进行模糊评价,综合评价结果为V;水资源价值WLJ=V·P,P是水资源价格向量,它是通过对水资源价格上限适当的分割构成,最后以北京市为例,对水资源价值模糊数学模型开展了实例研究,结果表明,水资源价值模糊数学模型符合实际,具有实际应用价值。
Water resources value (WRV) occupies an important place in sustainable utilization of water resources. The avaiable WRV models such as shadow price model, marginal opportunity cost model and supply-demand price model, each has merits and demerits, can not completely reflect WRV. WRV system is a complex system, fuzzy and complicated, composed of three interactive parts of society, economy and environment. Here the fuzzy model which consists of comprehensive evaluation of WRV (I) and calculation of WRV (or price) (II) is put forward. In part I, various factors which affect WRV are evaluated by fuzzy model with evaluation result being V. The water resources value WLJ=V.P, in which P is vector of WRV, coming from proper division of the maximum WRV. Finally, Beijing city is taken as a case study. The research result indicated that the fuzzy model of WRV is practical.
