【摘要】：地面沉降是北京平原區(qū)的主要地質(zhì)災(zāi)害之一。針對(duì)地下水長(zhǎng)期超量開(kāi)采引發(fā)的大范圍地面沉降,采用雷達(dá)遙感的技術(shù)方法對(duì)其進(jìn)行監(jiān)測(cè)分析:以2003~2010年間覆蓋北京的31景ENVISAT ASAR數(shù)據(jù)為基礎(chǔ),采用永久散射體干涉測(cè)量技術(shù)對(duì)北京市平原區(qū)進(jìn)行長(zhǎng)時(shí)間序列的地面沉降監(jiān)測(cè),并對(duì)比地下水水位變化數(shù)據(jù),通過(guò)GIS空間分析的方法討論地面沉降的時(shí)空演化特征。結(jié)果表明:2003~2010年,北京市平原區(qū)地表形變速率范圍為-52.1~8.2mm/yr,已經(jīng)形成五大沉降漏斗(朝陽(yáng)—通州沉降漏斗、天竺—金盞沉降漏斗、來(lái)廣營(yíng)沉降漏斗、高麗營(yíng)沉降漏斗和昌平沉降漏斗),地面沉降發(fā)生區(qū)域與地下水漏斗形成區(qū)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.
