一、概况温泉县属博尔塔拉蒙古自治州西部的一个边境县,博尔塔拉河由西向东横穿其间,河道两岸土层厚约5～13米,至山前坡地土层厚度逐渐减少到0.5～0.1米。干支渠和山溪水引水渠多数流经砂砾石和砂壤土组成的山前冲积──洪积扇地区。渗漏损失非常严重,土渠渠系利用率仅30％左右。因此,我们把水利工程的建设重点放在防渗渠道建设上,到目前为止,我县已建成防渗渠道488公里,其中 First, an overview Hot Springs County Bortala Mongolian Autonomous Prefecture in the western border of a county, Bortala River across the meantime from west to east, the river cross-strait thickness of about 5 to 13 meters, to the piedmont slope soil thickness gradually reduced To 0.5 to 0.1 meters. The majority of dry-branch and mountain stream diversion channels flow through the alluvial fan zone, which is formed by the gravel and sandy loam. Leakage loss is very serious, canal drainage system utilization rate is only about 30%. Therefore, we focus on the construction of water conservancy projects on the construction of seepage prevention channels, so far, our county has built 488 kilometers of anti-seepage channels, of which
