对我国的历史气候资料进行了分析，特别对我国华北地区的大气降水的时空分布进行了详细分析，在联合国政府间气候变化协调委员会（IPCC）推荐的若干个全球气候变化模式中选择了5个比较公认的模式，对我国未来（2030年）大气降水的变化趋势进行了初步分析，并总结了5个模型预测结果，对未来我国北方地区大气降水是否能缓解北方干旱给出了初步的判断。

In this paper, the historical precipitation data has been analyzed, the temporal spatial distribution of atmospheric precipitation of north and west of China have been studied in detail. Choosing 5 global climate change models recommended by IPCC, the atmospheric precipitation of China in 2030 has been analyzed under different scenario. Finally, the future trend of atmospheric precipitation in north and west of China is revealed and the preliminary judgment of the probability of mitigating the drought in north of China has been given.
