Abstract

Without doubt is one important aspects of sustainable forest management the continuing forest regeneration. Identify and determine is effective dispersal and distribution pattern of regeneration patches in various types of forest and its evolution, in maintaining biodiversity in natural ecosystems. Purpose was chosen of Gorazbon district Kheyrod forest for study, all patches regeneration were located in its. was used the analysis landscape metric in GIS and FRAGSTATS. Based on survey results, total were identified numbers of regeneration patches 723 in various types. Maximum and minimum were observed distance between patches in this study between 260 and 54 meters, respectively. According to measured the metrics, distribution pattern and patches structure in types Fagetum – Carpintum, Fagetum – orientalis and Carpinento - Fagetum than other types is of distribution and better uniformity, and can be used as regeneration natural pattern considered for follow of natural processes and sustainability and forest resources continue.
