摘　　要：龙岩台地磁观测室和记录室是在二十世纪八十年代龙岩地震台台址范围内进行选址建设的,其周围环境和磁场梯度还较为理想,而近几年来周边环境不断恶化,观测房离最近的道路只有约15米,受进出车辆干扰严重,观测室和记录室内磁场梯度(特别是观测室)已经严重不符合规范要求,部分磁场梯度达十几nT。由于我台台站范围较大(占地约35亩),特此在台站现有范围内进行了场地勘选,对场地的可用性进行分析,此文就征对此次场地的斟选过程及其可用性进行初步分析。The magnetic observation room and recording room of longyan Mesa were built within the site of longyan earthquake station in the 1980 s, and the surrounding environment and magnetic field gradient are still relatively ideal. In recent years, the surrounding environment has been deteriorating, and the observation room is only about 15 meters away from the nearest road. Due to serious interference from entering and leaving vehicles, the observation room and the recording room’s magnetic field gradient(especially the observation room) have seriously failed to meet the specifications, and some magnetic field gradients have reached more than ten nT. Due to the large area of Taiwan Station(covering an area of about 35 acres), we hereby conduct site survey within the existing scope of Taiwan Station to analyze the availability of the site. This article asks for a preliminary analysis of the selection process and availability of the site.
