摘 要:1.引言由二氧化碳等温室效应气体的增加造成的全球变暖问题是当前自然科学和政治生活的中心课题之一。从1958年起在夏威夷摩纳罗阿进行的大气中二氧化碳含量测定表明,大气中二氧化碳的浓度每年增加1~1.5ppm。根据此增加量和化石燃料消费量增加曲线及未来能源使用情况,预计到21世纪中叶,由于二氧化碳等温室效应气体增加将使地表平均气温增加1.5~4.5℃。The global warming caused by the increase of greenhouse effect gases such as carbon dioxide is one of the central issues for the present natural science and political life.The measurement of the carbon dioxide content in atmosphere conducted at Maunalua in Hawaii since 1958 shows that the carbon dioxide concentration in atmos- Phere has been increasing at an annual rate of 1—1.5ppm.According to this finding and the increase curve of the fossil fuel consumption and future energy use,it is forecasted that the average temperature of the earth's surface will increase by1.5—4.5℃ in the middle of the 21th century as a result of the increase of greenhouse ef- fect gases like carbon dioxide.In order to predict more correctly the accumulation of carbon dioxide in atmosphere and future climatic change,this paper concentrates on the basic data and concept necessary for establishing ac- curate climate models,the carbon dioxide cycle in atmosphere and the exchange of carbon dioxide among atmos- phere,oceans and land plants.
