中文摘要：

2006年8-10月在唐山一滦县地区布设了密集的临时地震台网，记录微震活动。临时台网由30台数字地震仪组成，台站间距为2—5km（其中2台仪器布设在唐山闹市区的大城山公园和南湖公园，进行强干扰背景下的地震观测试验）。现已得到由4个以上台站同时收到信号的398个地震的震源位置，而在相同时段从地震目录上仅能查到大约40次地震事件。这说明临时地震台网可以记录比区域台网更多的微震事件，为观测区构造研究提供更为丰富的基础信息。

英文摘要：

From August to October,2006, a temporary seismostation network was densely set up in Tangshan-Luanxian region to record the microearthquake. This network was composed of 30 digital seismographs, and the intervals between stations were about 2 to 5 km. Among these stations two were located at the Dachengshan Park and the Nanhu Park in Tangshan, which were used for earthquake observation experiments under strong interference background. For nearly 3 months, 398 hypocenter locations were recognised of which their signals were received simultaneously by more than 4 stations. In the same period, however, only about 40 earthquakes can be found in Regional Seismic Catalogue. It shows that more microearthquakes can be observed by the temporary seismic station network, and thus it provides plentiful basic informations for techtonic study in the observed region.
