摘要：在神农架川金丝猴生境典型地段设立样方,分析了植物群落种群的物种多样性和垂直结构特征。结果表明:α多样性,乔木层在低海拔的常绿阔叶林带最高,灌木层随海拔升高呈单峰格局,草本层在较高海拔物种多样性较高;β多样性总体上呈单峰变化,在中海拔建群种发生更替的落叶阔叶混交林区最高,物种更替速率最快,其次是山顶附近。沿海拔梯度升高,水热组合发生变化,在建群种发生更替的中海拔过渡带形成混交林带,总体上体现了过渡带具有高的物种多样性和更替速率,总物种丰富度呈沿海拔先升高而后降低的单峰格局。
The experimental plots in representative areas of the Shennongjia Nature Reserve were established.The forest communities in Shennongjia were investigated by using TWINSPAN.The plant communities in these plots were investigated to discern the pattern of species diversity distribution along the altitudinal gradient.The α-diversity and β-diversity were calculated by using the data collected.The α-diversity of the tree layer peaked in the evergreen broadleaved forest zone at low-elevation,the α-diversity of the shrub layer increased gradually at first and then decreased along the altitudinal gradient,while the α-diversity of the herb layer peaked in mid-altitude.The β-diversity peaked at mid-elevations where the composition of edificatory species changed.The transition zone was characterized by relatively high levels of species diversity and species turn-over rate.The overall species richness peaked in mid-altitude.The results of this research could provide a sound basis for reserve management and planning,as well as preservation of Sichuan snub-nosed monkey in this reserve.
