Abstract：A method of empirical mode decomposition was used to processe precipitable water vapor time series during 2000-2004 from GPS data of Crustal Movement Observation Network of China（CMONOC）and change trend of precipitable water vapor at every GPS station was obtained.The result of classification and comparison for the change trend indicates that the change trend in tropical monsoon climate zone，monsoon climate of subtropical zone，temperate continental climate zone and alpine climate zone is first up and then down；the change trend in temperate monsoon climate zone is first down and then up.
