首都圈地区前兆台网映震能力的强化方案研究

本文以首都圈地区现有前兆台网的映震能力评价为基础，提出了前兆台网强化的原则与方法。强化的原则是，以近期地震危险性研究成果为依据，以捕捉源兆信息为目标，以捕捉短临异常信息为重点。强化的途径是，对现有布局作适当的调整与优化，布设电磁波与断层土壤气为主的前兆台网，建设地下流体综合观测站与构筑地震前兆的立体化观测系统。

ON THE PLAN FOR INCREASING THE CAPACITY TO REFLECT SEISMICITY OF THE PRECURSOR OBSERVATION NETWORK IN THE CAPITAL AREA

On the basis of assessment on the capacity to reflect seismicity of the existing precursor observation network in the capital area, the authors proposed the principle and measure for increasing the capacity of the network in this paper. The principle is established based on the research results concerning about the recent seismic risks and aiming at the earthquake precursors from the source, the focus is put on the information of the imminent and short-term anomaly. The measure taken here includes modifying and optimizing the existing network, adding the EM wave precursor and fault-soil-gas precursor observation stations, and establishing the comprehensive ground-fluid observation stations, finally formed a three-dimensional observation system of seismic precursory.
