| 中文摘要 | 八步里沟流域内有4200—4300米,3700—3800米和 3000—3200米三级夷平面,沟口至八角有五级河流阶地。主沟北岸占流域面积的1/3,南岸占2/3。这种沟谷地貌特点经历了约200多万年的发展历史。自然历史上的泥石流比现代规模要大。八步里沟泥石流综合防治工程的完成并不意味着和泥石流作斗争的事业结束,效益观测和维修养护工作必须制度化,方能长久运用,发挥效益。 |
| 英文摘要 | The Babuli Gully is located in 31°27’ 19.8"-31° 30/32.5’/N, 101°56’45.7"-102 °03’41.1"/E. The drainage area is about 45km2,it appeared in the pentagon approximate toW-E direction.the length of the main gully is 14.22km, mean longit-uinal gradient of the gully-bed is 122.3‰. The lowest point of the valley is "at an elevation of 2135m, its highest point is 4446m, the maximum drop is 2311m. There has 3 grades of peneplain surface with 4200-4300m, 3700-3800m and 3000-3200m, in the Babuli Gully, which farmed successively in Oligocene,mio-cene and Pliocene; 5 grades of the Dajinchuan River terrace were formed from the Babuli Gully mouth to Bajiao in Quaternary; the sloping field occupies the most part of the drainage area, the north bank of the main gully is about 1/3 of all the valley, its south bank occupies approximately 2/3; the Quaternary glacier occurred in middle-upper reaches of the Babuli Gully.Thickness of water-rock flow deposit ir: 240m in the Babuli Gully for middle-Pleistocene. There has two layers of the viscidity debris flow deposit in the Ⅱ -terrace section, their scale is larger than the contemporary age. In 1987, the comprehensive control project of debris flow in Babuli Gully was all completes and tested up to standard. But this is not the end of a struggle with debris flow. Beneficial result observation and maintenance to strengthen some project systems can not neglect; on the basis of new conditions, to correct and improve installations concerned should be noticed. The benefit production units and administrative departments should all be concerned eith these problems. |
