| 摘 要： | 喇嘛溪沟既有沟谷发展演化的一般规律，同时也具其特殊性。现阶段喇嘛溪沟的溯源侵蚀已经超前，这与喇嘛溪沟多雨的天气和昔格达特殊地层岩性密切相关。喇嘛溪沟的溯源侵蚀已经趋缓，在科学合理的工程措施前提下，喇嘛溪沟地貌的演化将近于平衡，而对在建中的雅安—石棉—泸沽高速公路应尽可能不要太大改变沟的水力侵蚀状态。

| Abstract: | Nama Channel not only has the general rule of valley evolution but also has its unique features.At present,Nama Channel has been already eroded ahead of its source,which is closely related to rainy weather and rock character of Xigeda special formation lithology.However,headward erosion of Nama Channel has slowed down,and its landform evolution will be trend in balance based on scientific and reasonable engineering measures.Therefore it would not exert considerable influence on Ya＇an-Shimian-Lugu Expressway in construction. |
