海南七差地区植被数量分类

Quantitative Vegetation Classification of Qichai Region in Hainan Island

  • 摘要: 在对海南黎族七差地区野外植被调查基础上,得到物种数据和环境信息,并应用PC-ORD软件对样地数据进行分类排序。根据《中国植被》分类原则,并结合《广东植被》等相关资料,对分类结果作适度调整后,建立了七差地区植被分类系统。该地区植被可归入3个植被型组、8个植被型、2个群系组和6个群系。6个群系分别为木棉+厚皮+鸡尖群系(Form.Bombax ceiba+Lannea coromandelica+Terminalia nigrovenulosa)、南亚松群系(Form.Pinus latteri)、白茅群系(Form.Imperata arundinacea)、厚皮树+鹧鸪麻+木棉群系(Form.L.coromandelica+Kleinhovia hospital+B.ceiba)、陆均松+线枝蒲桃+竹叶青冈群系(Form.Dacrydium pierrei+Syzygium araiocladum+Cycloba-lanopsis bambusaefolia)、青梅+细仔龙+高山榕+白茶群系(Form.Vatica mangavhapoi+Ameslodendron chinense+Fi-cus altissima+Koilodepas hainanensis)。NMDS排序第一轴反映了土壤湿度梯度,第二排序轴反映了海拔高度梯度,样地在排序轴分布与实际情况相吻合。该地区植被形成、分布及变化与其特殊的气候条件及少数民族独特的生产方式有关系。

     

    Abstract: After species data and environmetal information were obtained based on vegetation surveys in Li minority region in Qichai,Hainan Island,a classification and ordination were made with PC-ORD software.After referring to the classification principles of"Chinese Vegetation",reviewing related research data such as"Guangdong Vegetation",and artificially adjusting quantitative classification results,the vegetation classification system of Qichai region was established.It includes three vegetation type groups,eight vegetation types,two formation groups and six formations.The six formations are discribed as Form.Bombax ceiba+Lannea coromandelica+Terminalia nigrovenulosa,Form.Pinus latteri,Form.Imperata arundinacea,Form.L.coromandelica+Kleinhovia hospital+B.ceiba,Form.Dacrydium pierrei+Syzygium araiocladum+Cyclobalanopsis bambusaefolia and Form.Vatica mangavhapoi+Ameslodendron chinense+Ficus altissima+Koilodepas hainanensis.The first axis of NMDS ordination expresses the gradients of soil moisture,while the second one depicts the height change of elevation.Therefore,plot arrangements in the axes are fitted with their practical distributions in the fields.The vegetation formation,distribution and change in the region may be related to its special climatic conditions and unique human activities of Li minority.
