This paper consists of four parts, which state to the effect that (i) Analyses and comparisons of efficiency of point sampling have been made. Materials indicate that efficiency of the point sampling was seriously affected by conditions of forests investigated; (2) Biases of omission were examined and analysed in both practice and theory. A method which can be used to eliminate biases of omission and estimate the size of biases is developed; (3) Comparisons have been made between the traditional method and the Meyer’s for estimating the change of forest resources, which show the latter is more efficient, but by this method it is not convenient for the current estimate of forest resources to be used as a basis for their next estimation; (4) According to the advantages and disadvantages of point sampling, the question of application of point sampling to continuous forest inventory and other matters that merit attention are discussed.
