摘　　要：利用TEQC软件对福建GPS连续观测台网不同时期建设的基准站的数据质量进行检测,给出各个基准站MP1、MP2和CSR值的年度报告统计表。根据IGS的质量标准及野外观测调查,得出:1)早期建设的多数基准站观测环境没有发生大的变化,部分台站周跳变化较剧烈,主要原因是台站遭受雷击而导致接收机性能下降、周围树木遮挡增强及周围电磁干扰所致;2)通过厦门和福州两个基准站的数据质量分析发现,新型接收机比老式接收机具有更强的抗周跳能力;3)"十一五"新建的30个基准站中90%优于IGS标准,个别台站指标偏高的原因是基准站周围树木遮挡增强所致。GPS data from 2004 to 2012 of continuous stations of Fujian GPS Observation Network were exam- ined using TEQC software ,and annual statistics report of MP1,MP2 and CSR for every station were organized. The comparison of IGS standard with field survey indicates ： 1 ） The M＆ and Mp2 value of the stations established in earli- er period was stable, some CSR values changed violently because of the lightning strikes, covering of the surrounding trees and electromagnetic interference within 100 meters. 2） Anti-cycle slips ability of the new GPS receivers are better then the old. 3 ）90% of the 30 stations new established are better than the IGS standard. The covering of surrounding trees leads to the index higher than the standard.
