| 本文在利用遥感技术和野外实地调查的基础上,研究了波密—林芝环境地质形成的主要控制因素,认为印度板块和欧亚板块碰撞形成的东部构造结及其所形成的活动断裂系统控制了研究区的地形地貌发育、水文气候和植被,进而控制洪涝、岩崩、泥石流、滑坡和崩塌,以及地震等灾害,并提出防治建议。 |

| Abstract: |
| The geological hazards and their genesis are examined for the Bomi-Nyingchi zone,Xizang with the aid of remote sensing image and field survey.The eastern syntaxis and active fault systems created by the Indian-Eurasian plate collision exercise a major control on the topographic and geomorphic features,hydrology,climate, vegetation plus flood calamity and rockfall,debris flow,landslides and earthquakes.Some suggestions are thus presented for the precaution and mitigation of the future geological hazards in the study area. |
