THE RELATIONSHIP BETWEEN GPS VERTICAL COMPONENT, RAINFALL AND GROUNDWATER IN QIONGZHONG STATIONS
摘要
Abstract
The relationship between precipitation,groundwater level and vertical component of GPS fixed-observation time series of images in Qiongzhong stations was systematically analyzed using groundwater and rainfall observation data of Jiaji well and Xiliu well during 1999 to 2012.The preliminary results show that rainfall,groundwater level and GPS vertical component all have a year cycle,and the relationship between each others is contravariant:when rainfall increases and groundwater level rises,the GPS vertical component decreases which means the land uplifts ;otherwise,when the rainfall decreases and the groundwater level declines,GPS vertical component increases which means the land subsidences.Finally,the mechanism of the GPS vertical component changes caused by the rainfall and groundwater level variation were discused.关键词
