大气中二氧化碳增加对气候及农业的影响

THE INCREASE OF CO_2 CONCENTRATION IN THE ATMOSPHERE AND ITS IMPLICATION ON CLIMATE AND AGRICULTURAL PRODUCTIVITY

本文综述人类活动对大气中二氧化碳的影响,回顾了温室气体与近百年来气候的变化。在综合国内外一些近期研究成果基础上,初步估计了温室效应引起的未来气候变化趋势——地面平均气温将可能在不断升降波动过程中趋于变暖。同时论述了二氧化碳增加及气候变暖对农业可能造成的重要影响。

The impact of man's activity on atmospheric carbon dioxide is summa- rized.Trend of green-house gas and climatic change during the last hundred years is reviewed.Problems in the prediction of the secular increase of surface air temperature(caused by increase of CO_2 content in atmosphere) and its possible impacts on agriculture are discussed.
