对旨在促进水资源保护的欧盟水框架指令(WFD)2000/60/EC进行检验,重点是改善地表水和地下水的生态和化学质量,并对供水成本进行了测算。WFD作为合适的可持续水资源管理系统中的一个工具,根据污染者付费原则,包含有供水全成本回收(FCR)概念。WFD确定了3项与水有关的不同成果,即资源成本(RC)、财务成本(FC)和环境成本(EC)。用能值方法从生物物理学角度对供水全部成本回收进行了测算,即确定来自不同水源的水的资源价值、与供水相关的全部经济成本,以及用水不善的社会成本,由此可分别计算水的资源成本、财务成本和环境成本。经分析得出,采用时空清晰的能值计算方法计算水的资源成本会有益于全成本回收。
Inspection of the European Union Water Framework Directive (WFD) 2000/60 / EC, which aims to promote the protection of water resources, focuses on improving the ecological and chemical quality of surface and groundwater and measures the cost of supplying water. As a tool in a suitable sustainable water resource management system, WFD incorporates the concept of full cost recovery (FCR) based on the polluter pays principle. The WFD identified three different water-related outcomes: Resource Cost (RC), Finance Cost (FC) and Environmental Cost (EC). The emergy method is used to calculate the total cost of water supply from a biophysical point of view, namely, to determine the resource value of water from different sources of water, the total economic costs associated with water supply, and the social costs of poor water supply, whereby water Resource costs, financial costs and environmental costs. The analysis shows that the use of a clear time and energy emergy calculation method of calculating the cost of resources of water will be beneficial to the full cost recovery.
