<正>本文试图将递推最小二乘估计引用于林业工作,以弥补林业上通行的最小二乘估计的不足,通过的阐释,并对所举两例计算的结果,说明了它既保持最小二乘估计的优良特性,又能在森林资源动态监测工作中充分发挥其特有作用。

To compensate for the shortcomings of the ordinary least square method; a new recurrence formula for it is presented and attempts are made to apply it in the forestry ,research work. The relevant equations are as follows:Two examples are given to show the use of the formula, which indicates that the new recurrence formula not only keeps the excellent properties of ordinary least square method but also can play a special role in the detection of dynamics of forest resources.
