苍山东坡植被垂直分布格局研究

Study on the altitudinal pattern of vegetation distribution along the eastern slope of Cangshan Mountain,Yunnan,China

  • 摘要: 苍山是中国高山植物模式标本的产地之一,具有较完整的植被垂直带谱.在对苍山东坡1966~4092 m沿海拔梯度进行植被调查的基础上,利用地形图和ETM+遥感影像进行苍山东坡植被制图,与数字高程模型(DEM)数据叠加,对苍山东坡植被景观的垂直分布格局进行了分析,并与顶级群落进行了对比.结果表明:苍山东坡绝大部分山体位于2500~3500 m范围.苍山东坡现状植被垂直分布格局明显,具有6个垂直分布带.该垂直植被带谱与顶级群落垂直带谱相比有一定变化.研究结果进一步量化了前人对苍山植被的垂直分布格局所做的定性和半定量的研究结果,找出了两者的差异,并进行了原因分析.

     

    Abstract: Cangshan Mountain is one of the alpine plant pattern samples collection areas in China.The vertical belts of vegetation are distinct and perfect.The vegetation map which is derived from contour map and remote sensing image was made out,based on vegetation investigation along altitudinal gradient from 1996 m to 4092 m.With the help of layer overlapping analysis of the vegetation map and digital elevation model (DEM),researches were made on the altitudinal pattern of vegetation distribution along the eastern slope of Cangshan Mountain,and the altitudinal belts were compared with the primary climax vegetation.The results are as follows: The most regions are distributed from 2500 m to 3500 m,along the eastern slope of Cangshan Mountain.The vertical structure is distinct.There are 6 altitudinal belts.There are some changings of the altitudinal belts between this reaserch and the primary climax vegetation.The vertical structure material results were made out and were compared with the previously reaserch.The differences were found out,and the reasons were analysised.
