摘要
未来４０～６０年内，人类活动将增大ＣＯ＿２、ＣＨ＿４、ＣＦＣ＿３和Ｎ＿２Ｏ等温室气体的排放，从而导致全球平均气温升高１～３℃。本文从我国农业和气候变化的趋势入手，分析了时全球变暖影响的敏感区和脆弱区，提出了适应对策并估算新增的投资和效益。
In the next four to six decades, enhanced emis-sions of the greenhouse gases:carbon dioxide, methane, chlo-roflorocarbon and nitrogen oxide rexulting from human activi-ties will increase the global mean surface temperature by 1- 3℃. According to the current trend of agricultural and climaticchanges in China, six sensitive agricultural areas and five re-gions with high vulnerability to the global warming impacts areindentified, In the meantime, adapted countermeasures are pro-Dosed in consideration of the incremental cost and benefitcaused by global warming.
