| 摘 要： | 雅鲁藏布流域发育高山垫状植被、干旱河谷植被、沙洲植被、亚热带植被和高山冰川植被等多种类型的植被，与各种侵蚀类型相互克制又相互适应。通过2年的野外调查和采样分析研究植被分布规律和与各种侵蚀的相互关系。峡谷亚热带植被的物种多样性、覆盖度和植被厚度都很高，水力和风力侵蚀完全被克制，但是重力侵蚀和泥石流侵蚀发育。高山垫状植被由...

| Abstract: | Various types of vegetation and erosion occur in the Yalutsangpo(Brahmaputra) River Basin.Field investigation was carried out in 2009 and 2010 studying the relation between the typical types of vegetation and erosion and the distributions of vegetation and erosion along the elevation.An alpine mat vegetation develops on the mountains with altitude over 4 000 m,with a coverage over 90% but a vegetation thickness of only 1~3 cm.The river valleys in the west part of the Yalutsangpo and the Lhasa River are very... |
