摘要

位于中国西藏自治区东南部的芒康地区受自然条件制约和人类活动影响，近年来滑坡等地质灾害频发，对电网建设运行、交通干线通行和人民生命财产安全构成严重威胁，亟需有效技术手段对该地区分布的滑坡灾害隐患进行探测识别，从而为防灾减灾提供决策信息支持。采用小基线集(SBAS)时间序列雷达干涉测量技术，对覆盖芒康地区的历史存档ALOS PALSAR和ENVISAT ASAR数据集进行处理分析，探测发现了分布在318国道沿线和金沙江河谷的多处疑似滑坡灾害隐患点，获得了潜在滑坡形变的空间分布图和时间演化特征，证明了时序InSAR技术应用于藏东区域地质灾害调查的可行性和有效性。

Abstract

In recent years

geological disasters like landslides have often occurred within the Markam area

which is located in the southeastern part of Tibet Autonomous Region. The stability of these landslides is affected by factors such as physical geographical/meteorological conditions and anthropogenic activities. These factors pose great threats to power grid construction/operation

major transportations

and public security. Hence

effective technologies are needed to detect potential landslide hazards within this area and provide key supports for decision making regarding disaster prevention and reduction. This study employed the small baseline subset InSAR technique to process archived SAR data stacks acquired by ALOS PALSAR and ENVISAT ASAR covering the Markam area. A few suspected landslide hazard sites are identified along National Highway 318 and the Valley of Jinsha River. Spatial distribution and temporal evolution patterns of the surface displacements upon these unstable slopes are characterized.
