| 摘 要： | 通过分析中国北方50 a来的降水资料,结果表明:干旱气候变化的主要特征表现在20世纪90年代夏季降水量有明显的减少趋势,干旱化趋势主要发生在北方,主要包括河北、山西、山东和西北地区东部.西北地区西部降水有明显增多趋势,西北地区东部降水量持续偏少,干旱连年发生.干旱气候的产生带来了严重的干旱灾害,无论从全国或甘肃省的近50 a来干旱灾害可以看出,90年代的干旱发生最为频繁,干旱灾情最为严重,2000年是干旱最严重的一年.干旱气候变化引发干旱化趋势明显,其影响程度非常严重和深远,应重视和加强干旱气候与干旱灾害的监测预测和防御对策的研究.

| Abstract: | Precipitation in North China in the 50 years is analyzed.It is found that the main features of arid climate change is that precipitation decreased obviously in the 1990s and aridity took place in the north,mainly in Hebei,Shanxi,Shandong provinces and the east part of Northwest.Precipitation in the west part of Northwest had increased obviously while in the east part of Northwest had decreased continuously with drought year after year.Arid climate brought serious arid calamity,and drought took place most frequently in the 1990s with serious loss,and 2000 was the most serious year.Arid climate change causes aridity obviously,the loss caused by drought become heavy and heavy.Therefore,the studies on arid climate and drought damage and how to control,monitor and predict drought should be reinforced. |
