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。

Abstract: | The annual precipitation variable characteristics and production structure were analyzed using a hundred years annual data of precipitation in the main body of arid and semi-arid area,in Central Asia and northwest of China The results indicated that the spatial 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. |

Keywords: | Central Asia northwest of China variability of rainfall production structure |
