| 摘 要： | 大气中CO_2含量升高引起的气候变化是目前人们十分关注的问题,地球变暖是不少科学家的共同看法.本文根据赵宗慈估算的CO_2含量增加1倍时对我国气候的可能影响,分析了这种变化对农业热量资源及农业生产的可能影响.结果表明:积温将增加无霜期延长,种植界线向北推移,对我国粮食产量的影响区域间差异较大,三北地区为增产趋势,华南为减产趋势.

| Abstract: | The problem of climatic change caused by the atmospheric CO2 content increasing is paid close attention by people . The globe warming is a common concern of most scientists . The possible impact of the climatic change of agricultural thermal resource and agricultural production were analysed according to the possible effect estimated by Zhao Zhongci when the CO2 content doubled. The results showed accumulated temperature and frost-free period would increase , plant boundary would move northward . The effect on grain yield in China depends on region . In Shanbei, the tendency is to increase the grain yield whereas in South China to decrease the grain yield . |
