Abstract：This paper uses continuous GPS observation data provided by UNAVCO to get height time series of each site, and extractes velocity field by leastsquare linear fit and eliminates the linear trend of the original series.Then we take spectral analysis and wavelet multiresolution analysis of time series.It can be seen that in the past ten years the Tianshan region shows overall uplift trend and has a good agreement between the various stations.Each station shows significant seasonal changes.
