Based on analyses of the actuality of the natural,social and economical resource of Tibet,using the research theory and the calculation methods of the relative carrying capacity of synthetic resources,and selecting some data such as:population,agrarian area and GDP,the relative carrying capacity of synthetic resource of Tibet was analyzed in the past twenty years.The result showed:the contribution of the carrying capacity of natural resources to the carrying capacity of synthetic resources is much higher than that of the carrying capacity of economic resources,and the increase of the carrying capacity of synthetic resource is generally lower than the population growth;The practical carrying capacity of synthetic resource is higher than the relative carrying capacity of synthetic resource,the carrying capacity of resource of Tibet is overloaded.At the same time,the existent causes of the carrying capacity of resource of Tibet was analyzed,and the paper discuss the countermeasures of solving conflict of the man-land relationship in Tibet was discusssed.
