【Abstract】 In this article,the basic operation conditions of the geoelectric field observation network in Shandong region is outlined,and then the data quality evaluation and analysis from the aspects of continuous rate,full rate,correlation coefficient,zero difference and the data-change curve are conducted. The results showed that:the data set of Tancheng,Heze,Dashan and Lingyang Seismic Stations is better in quality and of high accuracy.It can provide reliable data for seismic research.Otherwise, the data sets of Anqiu,Zoucheng and Rushan Seismic Stations are worse in quality,some indicators are failure and the data stability is not high.After preliminary analysis,it found that the observing environment,instrument stability,the operating conditions of observation unit(such as the working conditions of the electrode,the insulation and connection of the measuring line,etc.),data pre-processing levels and pre-scale effects are all important factors to the quality of the geoelectric field observation data.更多还原
