摘要：This work analyzes the quality of the restored forests with the prevalence of the Dipterocarpaceae family tree species in Binh Chau – Phuoc Buu Nature Reserve, Vietnam. To predict the number of plants in each diameter class, we verified the correspondence of theoretical distributions with an empirical distribution N - D. A theoretical model is best described by an exponential distribution. To establish natural regeneration, we determined the structure of renewed tree species and their relative thickness. The similarity between the composition of renewed plants and the composition of parent plants was determined by the Sorensen coefficient. A natural regeneration of 14 plant species is observed under the canopy of the Shorea formation. The similarity coefficient between the composition of the maternal stratum and renewed plants is 20.3%. This indicates that generations of renewed plants can alter the composition of maternal plants in the upper stratum. The analysis of the distribution structure of diameters and the similarity coefficient between the composition of the maternal tree and the renewed trees showed that the Shorea formation in the Reserve is in the process of succession to achieve a higher hierarchy of environmental stability, i.e., the climax stage.
