InSAR Time-Series Analysis of Land Subsidence under Different Land Use Types in the Eastern Beijing Plain, China
In the Beijing plain, the long-term groundwater overexploitation, exploitation, and the utilization of superficial urban space have led to land subsidence. In this study, the spatial–temporal analysis of land subsidence in Beijing was assessed by using the small baseline subset (SBAS) interferometric synthetic aperture radar (InSAR) technique based on 47 TerraSAR-X SAR images from 2010 to 2015....
متن کاملMeasuring Spatiotemporal Features of Land Subsidence, Groundwater Drawdown, and Compressible Layer Thickness in Beijing Plain, China
Beijing is located on multiple alluvial-pluvial fans with thick Quaternary unconsolidated sediments. It has suffered serious groundwater drawdown and land subsidence due to groundwater exploitation. This study aimed to introduce geographical distribution measure methods into land subsidence research characterizing, geographically, land subsidence, groundwater drawdown, and compressible layer th...
متن کاملLand Subsidence Evaluation Using Insar Time Series Analysis in Bangkok Metropolitan Area
There has been increasing interest over the last few years in the use of radar interferometry for land subsidence evaluation/monitoring. InSAR time series algorithms such as PSI and small baseline methods offer the possibility to measure ground displacements to a degree of accuracy comparable to traditional geodetic technique such as leveling. This preliminary work reveals the potential of time...
متن کاملLand subsidence and ground fissures in Xi'an, China 2005–2012 revealed by multi-band InSAR time-series analysis
a r t i c l e i n f o Keywords: InSAR StaMPS SBAS Land subsidence Ground fissure Fault Geohazards Xi'an Xi'an, China has been undergoing significant land subsidence along with ground fissure development. These geohazards have brought about severe damages to buildings, bridges and other facilities. In order to warn of and mitigate disasters, it is urgently necessary to obtain the latest rate, ex...
متن کاملSoil Respiration under Different Land Uses in Eastern China
Land-use change has a crucial influence on soil respiration, which further affects soil nutrient availability and carbon stock. We monitored soil respiration rates under different land-use types (tea gardens with three production levels, adjacent woodland, and a vegetable field) in Eastern China at weekly intervals over a year using the dynamic closed chamber method. The relationship between so...
