双河磨南德水源林自然保护区植被类型调查研究

Investigation and Study on Vegetation Types in Molande Water Source Forest Nature Reserve,Shuanghe

采用样线、样地及植被分类等方法,对双河磨南德水源林自然保护区植被类型进行调查研究。结果表明:保护区内植被类型丰富,植被保存较完整,共有6个植被型、9个植被亚型和15个群系,植被水平地带性分布不明显,而垂直地带性分布明显。依据云南植被类型分类系统,分别阐述了滇青冈-黄毛青冈林、滇石栎林,高山栲-元江栲林、旱冬瓜林、云南松林、滇石栎-白穗石栎灌丛、光叶石栎-高山栲灌丛等15个群系的植被类型特征,保护区内物种多样性丰富。

The vegetation types of Molande Water Source Forest Nature Reserve in Shuanghe were investigated by using the methods of transect,plot and vegetation classification.The results show that there are abundant vegetation types and complete vegetation preservation in the reserve.There are 6 vegetation types,9 vegetation subtypes and 15 formations.The horizontal zonal distribution of vegetation is not obvious,but the vertical zonal distribution is obvious.According to the classification system of vegetation types in Yunnan,the forests of Cyclobalanopsis glauca and Cyclobalanopsis glauca;Quercus yunnanensis forest;Castanopsis kawakamii forest and Castanopsis kawakamii forest in Yuanjiang;Dry white gourd forest;Yunnan pine forest;Quercus yunnanensis and Quercus glauca shrub;with the characteristics of vegetation types such as Quercus glauca and Castanopsis fargesii shrub were expounded respectively,the reserve is rich in species diversity.
