| 摘 要： | 确定林分空间结构是次生林保护和可持续经营的前提.次生针阔混交林是张广才岭最主要的林分类型,运用大小比数、角尺度、混交度3个空间结构参数研究张广才岭次生针阔混交林永久样地的空间结构.结果表明:样地大小比数为0.497,平均角尺度为0.538,平均混交度为0.630;针阔混交林林木相邻个体在垂直方向上分化不明显,存在激烈竞争的中层;林木配置处于中度到强度混交水平之间,林分总体上属于聚集分布格局;次生针阔混交林的空间结构特征已接近当地原始阔叶红松林水平.

| Abstract: | Spatial structure of stand is prerequisite for forest conservation and sustainable management. Secondary coniferous broad-leaved forest is the most important forest type in Zhangguangcai Mountain. Its stand spatial structure was studied by means of three structural diversity indicators:mingling, neighborhood comparison and neighborhood pattern. The mean neighborhood pattern, neighborhood comparison and mingling of this plot are 0. 538,0. 497 and 0. 630 respectively. The results indicate that the forest is between moderate mingling level and intensive mingling level horizontally, tree species differentiation is not apparent vertically, and the forest is aggregated. These characteristics of spatial structure suggest that secondary coniferous broad-leaved forest is approaching to virgin broad-leaved korean pine forest in Zhangguangcai Mountain. |
