天山北坡自然地理特征对河流产汇流影响的研究

本文扼要对比介绍了天山南、北坡的自然地理概况，着重分析了天山北坡山区的自然地理特征及其与产汇流的关系．通过对天山北坡山区分段、分流域的研究论证，总结出天山北坡是新疆重要的径流形成区，北坡降水量由西向东逐渐减少，河流长度与水量亦由西向东明显递减以及中山带是重要的径流形成区等几点结论．

On the Effect of the Natural Geographical Characteristics of Northern Slope in Tianshan Mountains on the Productivity and Confluence of Water

This paper briefly introduces comparatively the natural geographical characteristics of sorthern and northern slopes in Tianshan Mountains.It emphathetically analyzes the natural geographical features of the relationship with the productivity and confluence of water.Through study and proof on northern mountainous slope in Tianshan Mountains stage by stage and area by area,We can get the following conclusions.The northern slope of Tianshan Mountains is the important forming area of run off in Xinjiang.The amount of precipitation of northern slope decreases progressively from west to east,The lengths of rivers and the amount of water deceases obviously form west to east.The middle mountainous area of northern slope is the essential forming area of run-off.
