| 摘 要： | 利用最新的气象资料，计算并分析了中国北方地区与干旱有关的气象因素（可能蒸散量、水面蒸发量和降水量）的区域分布及其20世纪90年代的变化情况，结果表明，从总体上来看，20世纪90年代的干旱程度略轻于前30年的平均水平，但地区间存在显著差异，内蒙古东部地区，京津冀地区干旱有所缓解，山西大部分地区、陕西、宁夏南部、甘南及青海部分地区，则干旱有所发展，其它大部分地区的干旱程度几乎没有变化，最后，根据该地区的具体情况，提出了相应的防御干旱进一步发展的对策。

| Abstract: | The regional distribution of meteorological factors related with drought and its variation in 1990's were calculated and analyzed by using the newest meteorological data. The results showed that the drought degree in 1990's was slighter than that in former 30 years seeing from overall. But the differences existed in different regions. The drought degree in east part of Nei Monggol, Beijing, Tianjin and Hebei was relaxed than that in former 30 years, but it was developed in most part of Shanxi, south part of Shaanxi, Ningxia, Gansu and the part of Qinghai in 1990's. There was less variation in other regions. At last, according to the regional situation, the countermeasures of defending drought development were given. |
