水功能区考核指标体系研究初探

水功能区是实施最严格水资源管理制度的重要基础,本文从水功能区划理论、管理现状与考核要求,提出了水功能区考核指标体系建设的原则,并应用频度分析法、理论分析法和专家咨询法等建立了水功能区考核指标体系框架,确定了水文水资源、水环境、水生态和社会属性等四类作为属性层的构成,筛选出生态基流、敏感环境需水量、水质达标率、污染物入河控制量、鱼类多样性指数、珍稀物种生存状况、饮用水源地安全达标建设状况和水资源开发利用率等8个指标,最终确立了不同类型水功能区考核的关键指标和体系,为落实最严格的水资源管理制度奠定了良好的基础.

PRELIMINARY STUDY ON EVALUATION INDEX SYSTEM OF WATER FUNCTION ZONE

Water function zone is the important foundation to implement the most stringent water resources management policy, and to carry out the work of water resources protection. According to the theory, management and evaluation requirements of water function zoning, the principles and method for the construction of the water function zone evaluation index system were first build up, and then, the framework of the water function zone evaluation index system was established using frequency analysis, theoretical analysis and experts＂ consultation method. For a specified evaluation index system of the water function zone, there are four fields on the attribute level including and builds an evaluation index system for water function zone, which include hydrology and water resources, water environment, water ecology and social-water quality, water quantity, aquatic ecology, and social environment. Finally, eight indices such as eco logical basic flow, water demand for sensitive environments, the rate of water quality reaching standard, the controlling quantity of the pollution into the river, fish diversity index, living conditions of the rare species, construction of safety reaching standard of drinking water source and utilization ratio of water resources were selected as the evaluation indices. On this basis, the key evaluation indices and system for the different water function zones were established for better implementing the most stringent water management policy.
