中国地震台网布局的优化方案

根据现有中国地震台网的实际情况,目前地震预报的水平和可能达到的能力,提出地震台网的优化原则和实施方案。文中评述了近年来中国地震台网的发展和现有的监测能力。在西藏、新疆、甘肃,青海和黑龙江等边缘地区增加十个地震台站后,可以增强全国地震台网的监测能力,从而达到地震预报对资料的要求。最后还讨论了地震台网优化原则中的一些问题。

AN OPTIMUM SCHEME FOR DISTRIBUTION OF SEISMIC STATION NETWORKS IN CHINA

According to the present distribution of seismic station networks in china,the present level of earthquake prediction and the prediction capacity that may be reached,the optimum principle of the seismic station networks and it's implementing scheme are put forward in this peper. Firstly,the development of the seismic station networks in China and it's present detectability are reviewed.Then,it is shown that if ten more stations were added to the re- mote border region of Tibet,Xinjiang,Gansu,Qinghai and Heilongjiang,the detectability of the seismic station networks of China would be enhanced,meeting the earthquake pre- diction demands for seismic data.Finally,some problems in implementing the scheme are discussed.
