摘要: 阔叶红松林是东北东部最主要的林分类型,如何获取相应的林分结构信息是森林保护和可持续经营的重要内容。2011年,在吉林省蛟河试验局林场建立了1个面积为30hm2的阔叶红松林永久样地,并对样地内的每株树木测量了坐标、胸径和树高等。本文运用结构多样性指数(角尺度、大小比数、混交度)研究了该林分的空间结构。该样地的平均混交度值为0.590,平均角尺度为0.569,各个树种大小比数值介于0.36到0.94之间。这表明:张广才岭阔叶红松林树种空间配置稍高于中度混交水平,树种在垂直方向上分化明显,林分总体上呈聚集分布格局。研究结果可为森林的可持续经营提供借鉴。

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
