【摘要】：地面沉降是北京平原区的主要地质灾害之一。针对地下水长期超量开采引发的大范围地面沉降,采用雷达遥感的技术方法对其进行监测分析:以2003~2010年间覆盖北京的31景ENVISAT ASAR数据为基础,采用永久散射体干涉测量技术对北京市平原区进行长时间序列的地面沉降监测,并对比地下水水位变化数据,通过GIS空间分析的方法讨论地面沉降的时空演化特征。结果表明:2003~2010年,北京市平原区地表形变速率范围为-52.1~8.2mm/yr,已经形成五大沉降漏斗(朝阳—通州沉降漏斗、天竺—金盏沉降漏斗、来广营沉降漏斗、高丽营沉降漏斗和昌平沉降漏斗),地面沉降发生区域与地下水漏斗形成区域基本一致。
[Abstract]:Land subsidence is one of the main geological hazards in Beijing Plain. In view of the large-scale ground subsidence caused by long-term over-exploitation of groundwater, radar remote sensing technique is used to monitor and analyze it: based on 31 ENVISAT ASAR data covering Beijing from 2003 to 2010, The permanent scatterer interferometry is used to monitor the land subsidence in Beijing plain area in a long time series, and the variation data of groundwater level are compared. The temporal and spatial evolution characteristics of land subsidence are discussed by means of GIS spatial analysis. The results show that from 2003 to 2010, the rate of surface deformation in Beijing Plain is -52.1mm / yr, which has formed five major subsidence funnels (Chaoyang Tongzhou subsidence funnel, Tianzhu Jincalan subsidence funnel, Lai Guangying subsidence funnel). The subsidence funnel of Gaoliying and Changping is the same as that of groundwater.
