Abstract

Abstract: Dynamic characteristics of changes in the diameter of larch forests in the Lower Angara region are being analyzed. Larch stands of the herbal group of fox types is the object of the present research. This research is based on the data of field inventory 858 forest areas with larch predominance. The structure of the forest average diameter is approximated by the exponential function, statistical analysis of which has been carried out using a non-linear least-squares method and simulation methods by conducting 50000 statistical tests. Regularities of error distribution, parameters and calculation accuracy of approximating function have been defined. Estimations of parameter correlations approximating function have been suggested. Holetsky's method helped to receive two dimensional parameter generator. The defined regularities of the dynamics of average diameters allow to design economic activities in forest stands of larch herbal groups types in the region under study.
