我国城市水源水库水质风险成因及对策
Mechanisms and countermeasures of water quality risks in reservoirs using as drinking water sources in China
摘要
Abstract
Reservoirs(including lakes)play an important role in water supply to cities in China,which accounts for around 40％of supplies from reservoirs.Therefore,water security is one of the biggest challenges for urban water supply.Based on the literature on water quality in China's reservoirs,and investigation of yearly water quality at 22 typical reservoirs,we found that the water quality risks in drinking water source reservoirs mainly included taste & odor issues,cyanobacterial blooms,iron and manganese exceeding standards,organic matter and nutrients exceeding standards,etc.The above-mentioned water quality issues were mainly caused by overexploitation of the catchment area,increasing sediment and internal release,ecosystem imbalance,extreme climatic or hydro-logical events,and so on.To address these water quality issues,we proposed the following strategies including developing online monitoring and forecasting system,restrict of development in the catchment,developing a buffer system for non-point source nutri-ent control,sediment dredging,biomanipulation with fish stock,emergent bloom control and oxidation engineering,and environ-mental legislations.The reservoir ecosystem is sensitive to extreme weather events(e.g.,rainstorm and heat waves).Therefore,un-der the context of the warming and more extreme climatic conditions,further research should be paid attentions to fundamental eco-logical mechanisms of reservoirs,and thus improve managers understanding of the cause-effect relationship between climate change and reservoir water quality,and potentially provide the scientific supports to water safety and sustainable development.关键词
