淡水在我国尤其是北方地区属于稀缺资源,保护有限的淡水资源对实现经济社会可持续发展至关重要。保护作为淡水资源主要存在形式之一的水库水资源免遭污染破坏,对于实现保护稀缺淡水资源的意义重大。在经济社会发展的现阶段,要实现保护水库淡水资源免遭污染破坏的目的,除控制工农业污染物无序排放等措施外,应把合理发展水库渔业,维持水库生态平衡,减少水库富营养,控制蓝藻等藻类过度繁殖,提高水库水质作为治理重点,合理规 Freshwater is a scarce resource in our country, especially in the north. Protecting limited freshwater resources is crucial to achieving sustainable economic and social development. Protecting reservoir water resources as one of the main forms of freshwater resources from being polluted and contaminated is of great significance for the protection of scarce freshwater resources. At the present stage of economic and social development, in order to protect the fresh water resources of reservoirs from pollution and damage, in addition to controlling the disorderly discharge of industrial and agricultural pollutants, we should rationally develop reservoirs and fisheries, maintain the ecological balance of reservoirs, and reduce the reservoir eutrophication , Control algae such as cyanobacteria over-breeding, improve water quality as a reservoir focus, reasonable regulation
