摘要: |
常绿阔叶林是广西分布最广泛、最为复杂多样的植被类型。遵循《中国植被》一书的植被分类原则,并参考宋永昌先生的《中国常绿阔叶林分类试行方案》。根据高级单位以生态外貌、中级单位以优势度类型、低级单位以特征种组的分类原则,将广西常绿阔叶林划分出5个植被亚型、11个群系组和102个群系。在5个植被亚型中,典型常绿阔叶林和季风常绿阔叶林是地带性的植被类型,山地常绿阔叶苔藓林和山顶(山脊)苔藓矮林山地垂直带上的植被类型,而硬叶常绿阔叶林则是在广西特殊的石灰岩生境上存在的一种植被类型。 |

Abstract: |
The evergreen broad leaved forest is the most diverse and widely distribution vegetation type in Guangxi region. According to the principle of vegetation classification in vegetation of China,and with reference to the paper of “Tentative classification scheme of evergreen broad leaved forests of China” by Song Yongchang,the evergreen broad leaved forest of Guangxi was divided into 5 vegetation types,11 formation groups and 102 formations,based on the principle of that the high rank units of classification were based on eco physiognomy,while the median and the lower units were based on species composition,at the same time,the role of dominant species and diagnostic species was considered. Amid the 5 vegetation subtypes,the typical evergreen broad leaved forest and seasonal evergreen broad leaved forest were the zonal types of evergreen broad leaved forest. The mountain evergreen broad leaved forest and mountaintop mossy forest were the evergreen broad leaved forest types on vertical mountain,while the evergreen broad leaved sclerophyllous forest was the evergreen broad leaved forest types in the special condition of limestone habitat in Guangxi. |
