选取2008-2016年德令哈地震台水温观测数据，总结长期及短期变化特征，对影响数据变化的观测技术系统、观测环境及人为因素等干扰源进行分析。分析认为，观测技术系统故障干扰因素有供电故障、仪器故障、雷电影响等，该类干扰具有发生时间随机、持续时段较长，突变、异常变化幅度较大等特点；观测环境干扰有人工湖、黑石山水库、灌溉水渠等，该类干扰数据不稳定，具有突升、突降、突跳等特点；人为干扰有前兆仪器现场检修、仪器安装、施工改造等，具有持续时间短、突变、异常变化幅度较大等特点。
In this paper, the observation data of surface water temperature at Delinghart Seismic Station between 2008 and 2016 are selected to summarize the characteristics of long-term and short-term changes of the data. The observation technology system, observation environment interference, human interference and other interference sources that affect the changes of the data are analyzed and studied. It is believed that the existing interference factors of the observation technology system include power supply trouble, instrument trouble and lightning influence, etc., which have the characteristics of random occurrence time, long duration time, abrupt change and large abnormal change range. The observed environmental disturbance factors include artificial lake, Heishishan reservoir, irrigation canal, etc., which are unstable, and have the characteristics of sudden rise, abrupt fall and abrupt jump. Human interference factors include field overhaul of precursory instrument, installation of instrument, renovation and construction. The abnormal change characteristics of the data before and after the earthquake are analyzed and some research results are obtained.
