摘    要:运用植物群落学的调查方法,对云南省永仁县白马河林场的云南松Pinus yunnanensis原始林的群落特征及物种多样性进行了研究。结果表明:云南松原始林以云南松纯林为主,林下层次结构复杂,物种丰富。高位芽植物在云南松原始林内分布最多(46.1%),其后依次为地上芽植物(25.9%),地面芽植物(14.0%),隐芽植物(13.3%)和一年生植物(0.7%)。生活型谱反映了云南松原始林在其生长季节处于温热多湿的环境。云南松林木株数在径级分布上及在不同年龄段上均表现为中间多,两边少,趋向于对称性概率分布,表明了云南松原始林在演替过程中具有较好的稳定性。云南松原始林的Simpson指数、Shannon-Winener指数和Pielou均匀度指数Jsw,Jsi分别是云南松次生林的4.6,3.7,3.9和4.6倍,表明云南松原始林具有更丰富的物种多样性。图2表2参15

Abstract:Because the natural Pinus yunnanensis forests were devastated severely in 1960s and 1970s,today's P.yunnanensis forests are mainly secondary stands.The aim is to compare the difference of both forests to find the way renewing the secondary forests.In primary P.yunnanensis forest of Baimahe,in Yongren County,Yunnan Province,community properties and species diversity were investigated using the Raunkiaer system.Also,richness and evenness of species distribution were compared to secondary P.yunnanensis forests.Results showed that the primary forests were mostly pure P.yunnanensis,but with rich species and diverse structures in their understories.In the community investigated,phanerophytes represented the largest proportion(46.1%) followed by chamaephytes(25.9%),hemicryptophytes(14.0%),cryptophytes(13.3%),and therophytes(0.7%).This indicated that the environment of the primary P.yunnanensis forest was warm and humid during its growing seasons.The individual diameter at breast height and age of trees in the community followed a normal distribution,which indicated that the successional structure of the primary P.yunnanensis forests was relatively stable.For richness and evenness of species distribution in the primary forests,the Simpson index,Shannon-Wiener index,and Pielou evenness indices Jsw and Jsi were 4.6,3.7,3.9,and 4.6 times respectively more than these of secondary forests.This verified that primary P.yunnanensis forests had higher species diversity than secondary forests.Ch,2 fig.2 tab.15 ref.]
