摘要/Abstract

摘要： 本文介绍了卡尔曼线性滤波——动态递推估计及其在森林连续清查中的应用,并研究了使用线性滤波的两个估计值:(1)滤波差——滤波向量两个元素之差;(2)递推差——两期估计值之间的差。前者此后者更为有效,但后者便于保持两期估计值之间的相互一致。本文还提出了两期森林连续清查不同SPR方案的滤波公式,并根据吉林省一个林业局的三期清查结果,对有关这个方法的某些问题进行了讨论和分析。

Abstract: In the present paper an attempt was made to introduce Kalman's Linear Filtering and to apply it to the continuative forest inventory.Two estimated values of the linear filtering were used to estimate the changes of forest resources.One was the difference between two elements of flitering vector,i.e,flitering difference;the other was the difference between two estimators on two occasions.The former was more accurate than the latter,but the latter,is more suitable for maintaining the two estimators to be consistent.In addition,the formula of linear filtering,which was used in the various SPR projects of continuative forest inventory on the two occasions,was given and some associated problems were also discussed based on the results of forest inventories made in a forestry bureau of Jilin Province.
