长期过度开采地下水，静动荷载逐年增加，影响了北京区域地面沉降的发生和发展。利用2003 - 2009年Envisat先进合成孔径雷达数据，结合持久性散射体（persistent scattering for SAR interferometry）和小基线技术估算北京地区地面沉降信息。在不同的空间利用情况下，根据土地利用分类信息、多光谱遥感影像和地质资料，选择了5个典型聚落区。通过GIS空间分析，分析了不均匀沉降的时间序列演化特征。对比分析结果表明，对于5个典型沉降区，复杂的空间利用情况影响不均匀沉降趋势，较简单的空间利用情况（交通线路、建筑相对较少），沉降差异较小，不均匀沉降趋势较小。
Long-term over-exploitation of underground water, static and dynamic load is increasing year by year, which influenced the occurrence and development of regional land subsidence in Beijing, China. We used Envisat advanced synthetic aperture radar data acquired from 2003 to 2009 and PSI (persistent scatterers for SAR interferometry) and small baseline technology to estimate regional land subsidence information in Beijing, China. In different situation of space utilization, we chose five typical settlement areas according to classified information of land-use, multi-spectral remote sensing images and geological data. We analyzed the time-series evolution characteristics of uneven subsidence by GIS spatial analysis. The comparative analysis results suggest that for five typical settlement areas, the complex situations of space utilization affect the trend of uneven subsidence, the simpler space utilization situation (relatively fewer transport lines, construction), the smaller settlement differences and the smaller trend of the uneven subsidence.
