湖南舜皇山植物群落α多样性分析
|
摘要
为研究湖南舜皇山不同海拔区域的植物群落α多样性。对湖南舜皇山不同海拔高度植物群落的Patrick指数(R)、Shannon-Wiener指数(H)、Pielou指数(E)进行分析。结果表明:(1)在海拔400～600 m内,R、H的顺序为乔木层>灌木层>草本层(P<0.05),E为灌木层>(乔木层≈草本层)(P<0.05);在海拔600～1500 m内,R、H的顺序为灌木层>(乔木层≈草本层)(P<0.05),E为乔木层>(灌木层≈草本层)(P<0.05);(2)在相同的植物层中,(乔木层)[(400～600 m)(R, H)]>[(600～1500 m)(R, H)](P<0.05),E变化规律与R、H相反;(灌木层)[(1000～1500 m)(R,H)]>[(600～1000 m)(R, H)]>[(400～600 m)(R, H)](P<0.05);(灌木层)[(400～600 m)(E)]>[(600～1500 m)(E)](P<0.05);(草本层)[(600～1000 m)(R, E)]>[(400～600 m或1000～1500 m)(R, E)](P<0.05);(草本层)[(600～1000 m)(E)]>[(1000～1500 m)(E)]>[(400～600 m)(E)](P<0.05)。因此,不同海拔生境异质性是形成不同样点植物群落多样性差异的根本原因。
The paper aims to study α diversity of plant communities in different altitudes in Shunhuang mountain, Hunan, by analyzing the Patrick index(R), Shannon-Wiener index(H), Pielou index(E) of the plant communities. The results showed that:(1) from the altitude of 400 m to 600 m, R and H were followed the order as tree layer>shrub layer>herb layer(P<0.05) and E as shrub layer>(tree layer≈herb layer)(P<0.05),from the altitude of 600 m to 1500 m, R, H were followed the order as shrub layer>(tree layer≈herb layer)(P<0.05) and E as tree layer>(shrub layer≈herb layer)(P<0.05);(2) in the same plant layer,(tree layer)[(400-600 m)(R, H)]>[(600-1500 m)(R, H)](P<0.05), the change rule of E was opposite to that of R, H,(shrub layer)[(1000-1500 m)(R, H)]>[(600-1000 m)(R, H)]>[(400-600 m)(R, H)](P<0.05),(shrub layer)[(400-600 m)(E)]>[(600-1500 m)(E)](P<0.05),(herb layer)[(600-1000 m)(R, E)]>[(400-600 m or 1000-1500 m)(R, E)](P<0.05),(herb layer)[(600-1000 m)(E)]>[(1000-1500 m)(E)]>[(400-600 m)(E)](P<0.05).All in all, the heterogeneity of habitats in different altitudes is the critical reason causing the differences of plant communities in different sampling sites.
