长期超量开采地下资源、动静载荷逐年增加均在一定程度上影响着区域地面沉降的发生与发展，选取覆盖北京平原地区29景Envisat ASAR数据，采用融合永久散射体（PS）和小基线合成孔径雷达干涉测量技术，获取区域地面沉降时序监测信息。结合GIS空间分析方法，在区域浅表层空间（地铁、城市密集建筑群（CBD ）、立体交通网络设施）不同的利用模式下，选取5个典型地面沉降区域，结合土地利用分类信息、多光谱遥感影像、地质资料等，分析时间序列的不均匀沉降的演化规律。结果表明：浅地表空间利用的复杂情况在一定程度上影响着区域的不均匀沉降态势，空间利用情况越简单，沉降的梯度相对越小，不均匀沉降趋势越小。

Long-term over-exploitation of underground resources ,and static and dynamic load increase year by year influence the occurrence and development of regional land subsidence to a certain extent .Choosing 29 scenes Envisat ASAR images covering plain area of Beijing ,China ,the present paper used the multi-temporal InSAR method incorporating both persistent scatterer and small baseline approaches ,and obtained monitoring information of regional land subsidence .Under different situation of space development and utilization ,the authors chose five typical settlement areas ;With classified information of land-use ,multi-spec-tral remote sensing image ,and geological data ,and adopting GIS spatial analysis methods ,the authors analyzed the time series evolution characteristics of uneven settlement .The comprehensive analysis results suggests that the complex situations of space development and utilization affect the trend of uneven settlement ;the easier the situation of space development and utilization , the smaller the settlement gradient ,and the less the uneven settlement trend .
