黔中天龙山喀斯特次生林林分空间结构的量化与分析 总被引:2,自引:0,他引:2
评估林分的空间结构可为研究森林现状与生长发育过程提供重要信息,在林分的动态过程监测和指导植被的恢复与重建等方面具有重要研究意义。本文利用混交度、大小比数、角尺度3个空间结构指数,分析了黔中普定县天龙山喀斯特次生林2hm~2森林固定样地的林分空间结构特征。结果表明,天龙山喀斯特常绿落叶阔叶混交林的混交度、大小比数和角尺度分别为0.737、0.498和0.516,表明林分中林木种间处于高度混交状态,树木胸径的大小分化程度差异较小,并且树木处于轻度聚集分布状态。研究结果可为西南喀斯特地区天然次生林的空间结构优化以及植被的恢复与重建措施的制定提供参考。 相似文献
