102滑坡位于川藏公路(国道318线)波密至林芝之间,早在20世纪60年代已有明显活动迹象,多年来崩塌、滑坡、泥石流时有发生,常年断道阻车,严重影响了西藏同我国西南地区的交通与经贸交流。本文利用高分辨率QuickBird、IKONOS、Pleiades以及Landsat TM/ETM + 遥感卫星数据,解译出102滑坡2000年、2006年、2013滑坡破坏范围、冲沟、滑坡后壁等参数,结合1989 - 2014年102滑坡植被覆盖指数(NDVI),分析102滑坡近15年变化趋势及特征。结果显示: (1)102滑坡整体破坏范围呈逐年递减趋势, 2014年破坏范围与1992相比减小79%; (2) 2000 - 2013年滑坡右侧逐步稳定,滑坡左侧后壁向北扩展了约32 m,向东约47 m; (3)经过多年滑坡治理, 102滑坡发展趋势得到了一定控制,但是受滑坡后壁地下水以及强烈地形变化,滑坡左侧仍然处于不稳定状态; (4)受帕隆藏布江冲刷,滑坡前缘有向后退缩趋势。

Other Abstract

No. 102 landslide locates in Sichuan-Tibet Highway (National Highway 318) between Bomi and Linzhi. There are signs of activity in the early 1960s. For many years,collapse,landslide,debris flow damage road and seriously affect the transport and trade exchanges with Tibet in southwest China. In this paper,we interpret the damage range,gullies,main scarp of No. 102 landslide in 2000,2006,2013 by utilizing high-resolution satellite imagery (QuickBird, IKONOS, Pleiades), and integrate Normalized Difference Vegetation Index computed by Landsat TM/ETM + data with interpretation results to analyze the change trend of No. 102 landslide nearly 15 years. The results show that: (1) The damage range of No. 102 landslide is decreasing. The damage area in 2014 compared with 1992 is reduced by 79%. (2) The right side of landslide is gradually stable from 2000 to 2013. The left side of landslide main scarp extends northward 32 m and eastward 47 m; (3) After years of landslide treatment,the development trend of No. 102 landslide has been under control. But because of the groundwater and steep terrain,the left side of landslide is still in a precarious state; (4) Due to Purlung Tsangpo River water erosion,the landslide leading edge have receded trend.
