Abstract:

The annual precipitation variable characteristics andproduction structure were analyzed using a hundred years annual data of
precipitation in the main bo勿of arid and semi一arid area ,in Central Asia and northwest of China The results indicated that the patial distribution and time evolution of annual precipitation in this area not only show unitary features .but also unique feature.  In addition .a successful readjusted example of production structure was raised based on the analysis of rainfall characteristics in this area.

Key words: Central Asia, northwest of China, variability of rainfall, production structure

摘要:

利用近百年年降水量资料,分析了亚洲大陆干旱、半干旱地带的主体部分,即中亚和中国西北地区的年降水量变化特征和产业结构。分析结果表明,中亚和中国西北地区年降水量在空间分布和时间演变上,既表现出某些相似性,又呈现出独特性。并且根据降水特征分析,提出了半干旱地区产业结构调整的成功事例。
