On the basis of the study of cross-fault mobile deformation monitoring environment in the Capital Region of China, it is found that there are a few sites (near 20% ) impacted by the non-seismic factors. So we suggest that the crustal deformation monitoring techniques(instruments) and the cross-fault deformation surveying line layout should be improved and the cross-fault flow deformation level ling survey and baseline level of observation should be at the same pile. The baseline survey pile of existing level and baseline measurements should be technologically transformed at the appropriate time, in the measurement instrumentation: DiNi electronic level should be used instead of Ni002 Optical Level, Di2002 even TC2003 and TCA series of instruments should be used instead of the 24m traditional foot baseline deformation monitoring.%对首都圈地区跨断层流动形变监测环境的考察发现,某些监测场地中(近20％)存在一定的非地震因素影响.为减少非地震因素的影响,跨断层流动形变水准和基线应该同桩观测;测量仪器应该由具有更高测量精度和稳定性的DiNi电子水准仪代替Ni002光学水准仪,用Di2002甚至TC2003和TCA系列仪器代替传统的24m基线尺.
