摘　　要：近一个世纪以来,温室效应一直是困扰人类的一大环境问题。温室效应引起全球变暖,淡水生态系统也受到影响。温室效应加剧引起水温升高、水中含氧量下降、水体富营养化加速和水生生物多样性减少,造成全球降水量重新分配,早涝灾害发生频繁,江河湖泊的水量发生改变。控制温室效应最根本的途径是减少温室气体的排放。Nearly one hundred years, Greenhouse Effect has been one of the major environment problems. Greenhouse Effect causes the temperature rise and influences the freshwater ecosystem dissolved oxygen in water decrease, eutrophication in water body become serious and biodiversity in water degrade. It leads to changes in global rainfall distribution, frequency of floods and droughts, and water volume in the rivers and lakes. The most efficient way to control the Greenhouse Effect is that the emissions of greenhouse gases must be reduced.
