| 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。

The Arid Climate Variable Characteristics and Its Influence on Production Structure in the Central Asia and Northwest of China |
| |
| 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. |
