摘要：

This paper presents a method based on angle-gauge sampling useful for inventorying downed coarse woody material in forest stands. The method is closely related to transect relascope sampling, except that sample points are used rather than line transects. The estimators for the total and per unit area are given along with the estimators of their variances. Methods for handling both borderline material and boundary overlap situations are also presented.
