To meet the needs of assessing the target completion of the National “Twelfth Five-Year” Program Outlines,two improved methods were presented in this study,based on the methods for producing annual national estimates of forest resources presented by the first author in 2013,which were “sequent-shifting” method and “comprehensive compromise” method.Then,by using the main data of national forest inventories (NFI)after the 5thNFI,the different methods were compared and analyzed for the timeliness,stability,and certainty of the national estimates.The advantages and disadvantages of the methods need to be evaluated based on a comprehensive analysis of the annual results.Especially,in considering the timeliness of the national estimates,it is necessary to take into account the harmony between the annual data and the published periodic data.
