【摘要】 岗松(Baeckea frutescens)是桃金娘科岗松属植物,分布于东南亚和我国南部。本文根据广泛的野外调查,定出了岗松在我国南部的分布范围,并根据生态地理条件将岗松的分布区分为南部、中部和北部三个亚区。经分析得出其垂直分布高度与纬度的关系式为;H≈-163.64Ln+4772.36文章还探讨了岗松的分布同温度、光照、水分、土壤、河谷地形与人为影响的关系。更多还原

【Abstract】 Backea frutescens L. (Myrtaceae ) is widely distributed in the south-east Asia. According to investigation, the distribution of B. frutescens inour country should be divided into three parts: North, Middle and southsubareas. The relation between the height of its vertical drstribution andthe latitude (north) can be given as: H≈-163.64Ln + 4 772.36. The ecological factors is the limitary factors of its dictribution. sowe have also studied how the temperature, soil, light, water and topogra-phy influence upon the distribution of B. frutescens.更多还原
