Abstract

Abstract: Broad-leaved korean pine forest is the most important forest type in Eastern region of Northeast China.And how to obtain the appropriate information on forest structure is an important part of forest conservation and sustainable management.In 2011,a permanent plot of 30ha was established in forest region of Jiaohe Forestry Experimentation Administrative Bureau,in which all trees were sized by diameter breast height(DBH)and mapped.Its stand spatial structure was studied by means of three structural diversity indicators:mingling,neighborhood comparison and neighborhood pattern.The mean mingling of this plot is 0.59,the mean neighborhood pattern is 0.569 and neighborhood comparison is between 0.36 and 0.94.The results indicate that the forest is slightly above moderate mingling level horizontally,tree species differentiation is apparent vertically,and the forest is aggregated.The results can provide a reference for the forest sustainable management.

Key words: broad-leaved korean pine forest, spatial structure, mingling, neighborhood comparison, neighborhood pattern
