- 摘要:
- 对藏东南地区不同坡向及海拔高度下云南松次生林中植物种类、主要物种重要值、植物物种多样性等进行了调查，以揭示云南松次生林中植物空间分布格局。结果表明：样地内共有植物20科32属41种，单科单属单种物种相对较多。云南松的重要值阳坡高于阴坡，随海拔高度的增加而增加；所有植物阴、阳坡重要值均存在一定差异，灌木中阳坡海拔2 100 m处拟变缘小檗重要值最高，海拔2 300、2 500 m处雅致山蚂蟥重要值最高；阴坡2 100、2 300 m处拟变缘小檗重要值最高，2 500 m处米饭花重要值最高；阴、阳坡不同海拔高度所有植物中，蕨的重要值阳坡随海拔高度先升高后降低，阴坡随海拔高度上升而下降。物种丰富度指数阴坡高于阳坡，阴坡海拔2 300 m处最高，阳坡物种丰富度指数随海拔升高呈下降趋势；物种Pielou均匀度指数、物种Shannon-Wiener、Simpson多样性指数阴坡均高于阳坡，随海拔的上升逐渐降低。
- Abstract:
- This study was to illustrate the distribution patterns of secondary Pinus yunnanensis forest,plant species,species important values and species diversity were analyzed based on an investigation of secondary Pinus yunnanensis forest in southeast Tibet.The results showed that the survey plots had high plant species richness,with 41 species belonging to 20 families and 32 genera.The species important value of Pinus yunnanensis in sunny slope was higher than on the shady slope in all altitude in our study,and increased with the altitude elevating.In shrub,the highest species important value was Berberis julianae Schneid at the altitude of 2 100 m and Desmodium elegans at the altitude of 2 300,2 500 m in sunny slope.Berberis julianae Schneid showed highest species important value at the altitude of 2 100 m and 2 300 m in shady slope,Lyonia ovalifolia took the first place when the altitude was 2 500 m.Pteridium aquilinum just below Pinus yunnanensis in all experiment altitude and slope,increased first and then decreased in sunny slope,but continuously reduced in shady slope with the altitude elevating.The species richness index in shady slope was higher than in sunny slope,the maximum species richness index was at the altitude of 2 300 m in shady,and decreased with the altitude elevating in sunny slope.The shannon index,pielou index and simpson index in shady slope was higher than in sunny slope,and decreased with the altitude elevating.
