摘要: 岷江柏(Cupressus chengiana)是国家Ⅱ级保护物种,主要分布于岷江、大渡河和白龙江流域。不同干扰强度下的岷江柏群落特征研究鲜有报道。本研究以干扰种类和强度为基础,分析了重度、中度和轻度干扰强度下的岷江柏群落物种多样性和群落特征。结果表明:重度、中度和轻度干扰强度下的岷江柏群落分别由30、43和50种物种组成,重度干扰与中、轻度干扰的物种多样性有显著性差异(P<0.05)。重、中、轻度干扰强度下乔木层岷江柏重要值依次为256.09、154.09和116.19,灌木层中岷江柏幼苗幼树的重要值依次为107.08、25.44、29.27,重要值均高于其他物种。研究认为,人为干扰对岷江柏群落的物种多样性组成有显著影响。

Abstract: The Cupressus chengiana S.Y.Hu is one of national Ⅱ level protected species,mainly distributed in the basins of the Minjiang,Dadu and Bailong Rivers in China.Based on the disturbance type and intensity,C.chengiana forests were divided into severe,moderate and mild disturbance types,respectively.In order to answer the affects of different disturbance intensity on C.chengiana ommunity characteristics,analysis was made of species diversity and important values under different disturbance types.The results showed that under the severe,moderate and mild interference intensity,the species of C.chengiana forests consisted of 30,43,and 50 species respectively,and the different interference intensity had a significant effect on C.chengiana community species diversity (P<0.05).Under heavy,moderate and mild disturbance,the importance values of tree layer in Cupressus chengiana were 256.09、154.09 and 116.19 respectivehy.The important values of shrub layer in Cupressus chengiana seedlings and saplings were 107.08,5.44 and 29.27,being higher than those of other species.The studies have shown that human disturbance has a significant influence on Cupressus species diversity composition.
