摘要
以天山头屯河为例，通过对河流水沙情势的分析，探讨了干旱区河流不同地段的产输沙特点，提出了干旱区山溪性河流泥沙源于中低山带；同时结合不同地段（不同海拔）的地质、地貌及气候、土壤等植被生长条件。
Taking the Toutun River as an example, the feature of the production and delivery of the sands in land valley are studied by analyzing the water and sand condition of the river, and the conclusion that the sands source of mountainous streams is in low mountain belts is obtained. The concrete biological measurement of development and protection and the regional administer counterment of water and soil conservation linking with geology, landforms, climate, soil and other conditions that affect the growth of vegetation in different sectors of the area (or different elevations)is put forward.
