当前世界环境

在印度卡纳塔克邦Brahmagiri野生动物保护区的25个20 m × 20 m的随机样方中，研究了浅藻林生态系统的树种组成和结构。经点算的树种65种，隶属于35科47属，林分密度为1507 (?1公顷面积1厘米胸径)的树木。研究区Shannon’s、Simpson’s和Fisher’s α多样性指数分别为3.654、0.960和15.471。调查树木基材面积为31.19 m2 ha-1。西高止山脉特有17种(26%)。从密度上看，梧桐(Symplocos cochinchinensis)居优势，其次为菲律宾Celtis philippensis、Elaeocarpus serratus、女贞(liustrum robustum)和马来樟(Cinnamomum malabatrum)。樟科最多，共有11种，茜草科次之，有6种。低直径级(?10cm DBH) individuals were having higher proportion (67% (1007 individuals)) than that of the adult class (500 individuals) which indicated that the forest shows a good regeneration potential. However, few species including two endemic species have poor regeneration status. This enlightens that a thorough understanding of those species’ regeneration potential is warranted in order to carry out proper management plans and conservation.
