摘　　要：本文利用首都圈跨断层形变观测和观测场地的综合调研结果,对跨断层基线、水准各测项的综合效能进行评估,对断层整体活动信息进行分析提取,对首都圈地区强震的映震效能进行分析研究。利用首都圈地区流动重力区域测网的观测结果,分析重力场动态变化特征,对近期首都圈地区的地震趋势进行预测。In this paper,based on the cross-fault deformation survey and the result of comprehensive investigation of observation sites in the Capital area,we evaluate the comprehensive efficiency of whole baseline and level item,analyze and extract the integer movement information of faults,and study the efficiency of reflection for strong earthquakes in the Capital area of China.Using the observed results of the regional coverage of mobile gravity,we also analyze the dynamic variation characteristics of gravity field for the forecasting of the earthquake trend in the near future.
