| 摘 要： | 测站周围的环境会对GPS观测产生多路径效应影响，利用TEQC软件分析武汉九峰台站的近十年的GPS数据，并对结果进行了频谱分析，发现GPS多路径效应与台站周围植被覆盖情况存在着一致的周年的变化规律。因此，可以利用GPS的多路径效应来研究植被覆盖率的变化。

| Abstract: | The GPS data quality can be effected by the environ- ment around the GPS observation station. And the vegetation coverage around observation station can arouse variety of the multipath effects. In this paper, nearly a decade GPS data se- ries of National Geodetic Observatory in Wuhan were processed by TEQC and we found that there was a consistent annual variation trend between the multipath effects and the vegetation coverage around observation station, which can be used to study the change of vegetation coverage via GPS multipath effects. |
