摘要
依据已有的大量研究结果,通过对未来气候变暖情景下CO2浓度倍增时我国农作物的气候模拟分析的总结,结合历史上暖期我国西北农业生产的情况及个例分析,得出:当气候变暖时,我国西北地区降水增加的可能性较大,西北地区并没有因温度升高而变干,从而有利于西北粮食产量的增加。
On the basis of current research data and through CO_2--multiplying simulation for crops with the prospect of climatic warming in China as well as summarization and case studies of historical performance of agricultural production in northwest China, the paper points out that the rainfall-increasing livelihood will tend to rise while the climate becomes warmer; but the increased temperature will not make northwest China become dry and thus is helpful to increase the grain yields of northwest China.
