摘要
大气 CO_2增加导致的全球气候变化在空间上存在着显著的差异.采用不同方法得出温度和水分变化的地域差异是基本一致的,由此,对不同地区农业生产可能造成的影响也是不同的.因此世界各国对 CO_2这一全球性环境问题企图达成协调一致的行动纲领可能是困难的.
More and more attentions have been paid to the global warming caused by CO_2 con- centration in atmosphere.It may be considerably important for geographers to investi- gate the responses of every region in the world to the global temperature rising.The re- gional differences of temperature increase and rainfall change relating to the CO_2—in- duced global warming have been reviewed,and the implications of the regional differ- ences in climatic change,both for ecosystems and the agriculture over each continent, have been discussed. The temperature increase will probably be more obvious in the high latitude zones than that in the low latitude zones,and the rise of summer temperature in the eastern U- nited States will be larger than that in the eastern China.It has been confirmed that the central North America will become drier in a warmer earth,while North Africa,most parts of India and the eastern China will be quite possible to experience more humid cli- mate on the background of the future global warming. Some regions on the earth will suffer from the global climatic change,others will benefit from it.The author,therefore,considers it possibly difficult for all the countries of the world to reach an agreement on the action to deal with the CO_2 problems in the coming years.
