摘    要:利用河南省宝天曼国家级自然保护区32块样地资料,通过划分不同的群落类型,利用Simpson指数(D),Shannon-Wiener指数(H)和Pielou指数(R)等3个物种多样性指数及改进的M-Godron稳定性测定方法分别对该区物种多样性和群落稳定性进行测度,研究了栎类Quercus天然林群落物种多样性和稳定性的耦合相关关系。结果表明:群落A,群落B,群落C和群落D的稳定性数值分别为0.084 6,0.239 4,0.291 7和6.456 6,除群落D处于不稳定状态,其他3个群落类型均处于稳定状态,且稳定值差别不大;所有植物Simpson指数、 Shannon-Wiener指数和Pielou指数与群落稳定性数值之间相关系数分别为0.998 3,0.968 0和0.999 7。以95%的置信概率检验结果表明,两者存在着显著的正相关关系,即植物群落的物种多样性越高,结构越复杂,稳定性就越强。图2表2参15

关 键 词:森林生态学  改进M-Godron法  群落稳定性  物种多样性  天然次生林群落  宝天曼国家级自然保护区

Abstract:To measure and study the values and relationships between community diversity and stability of four communities(A,B,C,and D) in a natural Quercus(oak) forest,data from thirty-two sample plots of the Baotianman Nature Reserve in Henan Province were obtained and analyzed according to three diversity indexes: the Simpson index(D),the Shannon-Wiener index(H),and the Pielou index(R) as well as a community stability index:the improved M-Godron method.A correlation analysis of the three diversity indexes to the co...
Keywords:forest ecology  improved M-Godron method  community stability  species diversity  natural secondary forest community  Baotianman National Nature Reserve
