水功能区水质达标评价浅议

Preliminary discussion on evaluation of water quality up-to-standard in water function zone

水功能区水质达标评价是开展水功能区管理的基础,为利于最严格水资源管理制度的实施,亟需对水功能区水质达标评价工作开展系统研究。结合水利系统在水功能区水质达标评价工作中遇到的实际问题,分析了《地表水资源质量评价技术规程》、《水环境监测规范》在评价范围、监测频次要求、评价技术要求、评价项目设置、监测断面设置等方面存在的不足,并提出相应的调整建议。

Up-to-standard evaluation of water quality is the foundation of water function zone management. For implemen-ting the most stringent water resources management system, it is necessary to carry out systematic research on up-to-standard condition of water quality in water function zone. By summarizing the practical problems encountered in up-to-standard evalua-tion of water quality in water function zone, aiming at two specifications of “Technical Guidance for Water Quality Evaluation of Surface Water Resources”and“Specification of Water Environment Monitoring”, we analyze their defects from aspects of evalua-tion range, monitoring frequency requirement, technical requirement, evaluation item arrangement, deployment of monitoring sections, and corresponding countermeasures are put forward.
