摘要
云南省作为我国西南地区与西藏相连的省份,其地势由西北向东南逐渐降低且山峦众多,山区面积占全省面积的88%。除此之外,云南省还位于印度洋板块和亚欧板块交界处附近,其地震带众多,地质运动频繁,经常出现地震、滑坡、泥石流等地质灾害。因此,本文选取覆盖地势较高的云南西北部地区的哨兵数据,利用SBAS-InSAR技术进行数据处理,针对云南西北部地区的地表形变进行监测,发现地质灾害隐患区域,为地质灾害预警提供数据支持。
As a province connected to Tibet in southwestern in our country,the terrain of Yunnan province gradually decreases from the northwest to the southeast,and there are many mountains.The mountains area can account for 88%of the province’s area.In addition,Yunnan province is also located near the junction of the Indian Ocean plate and the Asia-Europe plate.It has many seismic belts and frequent geological movements,and there are frequent geological disasters such as earthquakes,landslides and mudslides.Therefore,this paper selects Sentinel data from northwestern in Yunnan,which covers a relatively high terrain,and uses SBAS-InSAR technology for data processing.The purpose is to monitor the surface deformation in northwestern in Yunnan and discover hidden areas of geological hazards,which will be the subsequent geological hazards.Early warning is provided on data support.
