| 摘 要： | 采用地下水动态监测网、GPS监测网数据、气象监测数据与SAR数据、GIS等技术相结合,建立地下水系统演化与地面沉降过程模型,系统分析了北京地区地下水降落漏斗区地面沉降的形成过程。研究表明:降雨量呈逐年下降趋势,地下水开采量随之增大;平原区地下水位呈下降趋势,间接导致了地下水降落漏斗和地面沉降的形成演化。地面沉降对地下水降落漏斗的响应模式存在着季节与年际差异性,时空分布上存在不均匀性,最大地面沉降速率约为41.43 mm/a;揭示了地下水降落漏斗与地面沉降漏斗空间展布特性存在一致性,但并非完全吻合。

| Abstract: | The model of land subsidence and groundwater evolution process was created though the combining of groundwater monitoring network,GPS monitoring network data,radar satellite SAR data,GIS and other new technologies gave a systematical analysis of land subsidence formation in groundwater funnel zones of Beijing area.The authors show that groundwater extraction increases along with precipitation declination year and year as the impact of global warming;the trend of groundwater table drawdown leads to the funnel shape of groundwater and land subsidence evolution in the plain area.Temporal and spatial non-uniformity was found in this study.Seasonal and interannual differences exists in the response model of land subsidence to groundwater funnel,and the maximum land subsidence rate was about 41.43 mm/a.A consistency exists between the spatial distribution of groundwater funnel and land subsidence funnel,but not entirely. |
