| 摘 要： | 以我国现行森林资源清查体系为基础,研究提出了3种全国森林资源年度出数的方法,并针对目前可行的年度滚动和更新预测两种方法,利用第五次到第八次的全国森林资源清查结果,从数据时效性、稳定性和确定性等方面进行了对比分析。结果表明:更新预测方法能有效解决数据的时效性问题,确保年度数据稳定可靠,是目前值得推荐使用的可行方法。

| Abstract: | Based on the current national continuous forest inventory(NFI)system in China,three methods for producing annual national estimates of forest resources were presented at first.Then,by using the main data of national forest inventories from the 5th to 8th NFIs,the two feasible methods at the moment,"annual-rolling" method and "updating + predicting" method,were compared for the time-effectiveness,stability,and certainty of the national estimates.The results showed that the "updating + predicting" method can produce time-effective,stable and reliable annual national estimates,which is worthy to be recommended for application at present. |
