摘 要:闽江干—支流众多水利工程的建成和运营,显著地影响和改变了闽江干—支流河流的水动力场和水化学场的时空状态,导致其纳污量(强度)、稀释扩散净化能力、水化学成分和水体质量等水文环境参数发生变化,引起水文环境灾(危)害问题日益突出。本文概述了闽江干—支流点源污染及面源污染程度和时空状态及其与水利工程建设运营的关系,同时以水口水库为例,探讨了水口电站水库的蓄水调度运营对闽江下游福州段及河口段水环境的危害作用,以及可能引发的闽江下游水生态灾害和危害福州市等重要城市供水水源质量和安全等问题。Many water conservancy projects in the main and branch waterways of Minjiang River have been built and used.They have observably affected and changed the space-time state of hydrodynamic field and hydrochemical field of Minjiang River and its branch waterways,and caused the changes of hydrological environment capacity,dilution ratio,the ability of transportation and purification,the chemical composition of water,water quality standards,hydrological and environmental parameters and so on.At the same time,the hydrological environment disasters have also become an acute problem.This paper summarizes the main content of the contamination degree of point source and non-point source pollution,its space-time state and its relationship with water conservancy construction and operation.Meanwhile,taking Shuikou Reservoir as an example,the paper has a preliminary discussion that the storage,dispatching and operation of Shuikou Reservoir have harmful effects on the water environment of Fuzhou section and of the estuary section on the lower reaches of Minjiang River,and might cause severe problems of the water ecology of the lower reaches of Minjiang River and the quality and safety of the water supply source for Fuzhou and other cities.
