In this paper,we used observational radiation data from the Amdo Center Station (The following is the Amdo Station,with 19 years of surface radiation observations), BJ Station (with 17 years of surface radiation observations), D105 Station (with 17 years of surface radiation observations) and NPAM (Also known as the MS3478 Site,with 17 years of surface radiation observations) Station on the Northern Qinghai-Tibetan Plateau in the GAME /Tibet [GEWEX (Global Energy and Water cycle Experiment) Asian Monsoon Experiment on the Qinghai-Tibetan Plateau] and the CAMP /Tibet [CEOP (Coordinated Enhanced Observing Period) Asia-Australia Monsoon Project (CAMP) on the Qinghai-Tibetan Plateau],and the Qomolangma Station for Atmosphere and Environment Observation and Research of the Chinese Academy of Sciences (The following is the Qomolangma Station,with 12 years of surface radiation observations) and Nam Co Station for Multisphere Observation and Research of the Chinese Academy of Sciences (The following is the Nam Co Station,with 12 years of surface radiation observations). There are about 10 to 20 years of observational radiation data,calculated the daily average value at 10: 00 to 18: 00 on sunny days,and counted monthly average value. Finally,use these average value to find out the annual average value of observational surface radiation fluxes (short wave downward radiation, short wave upward radiation,long wave downward radiation,long wave upward radiation,net radiation flux and albedo) from the above sites. Based on the analysis of the annual variations of short wave downward radiation,short wave upward radiation,long wave upward radiation,long wave downward radiation,net radiation and albedo of the typical underlying surface (plateau meadows with a height of 5 cm,plateau meadows with a height of 10 cm,sparse plateau meadows,plateau meadows with a height of 15 cm,gobi,and plateau meadows near the lake), the longterm climate change characteristics of surface radiation fluxes of the Qinghai-Tibetan Plateau were obtained. It was found that the short wave downward radiation flux at most sites on the Qinghai-Tibetan Plateau has a decreasing trend of varying degrees of annual change. Moreover,the long wave upward radiation flux by all the stations has an increasing trend of varying degrees,and the long wave downward radiation flux by all the stations has an increasing trend of varying degrees. The annual variation of the net radiation flux at most stations in the Qinghai-Tibetan Plateau region is basically consistent with the annual change in the short wave downward radiation. And the albedo at most sites on the Qinghai-Tibetan Plateau decreases year by year to varying degrees.
