| 摘 要： | 本文首先综述前人对伏牛山南侧热带北界划分的研究成果，并指出了产生分歧的原因。然后作者通过对伏牛山中段南坡不同海拔高度七个土壤剖面的野外调查和室内土壤腐殖质组成和性质的分析，选择各剖面点的海拔高度、有机碳、胡敏酸（HA）、富有酸（FA）、胡富比（HA／FA）、E4、E6、E4／E6等指标，运用聚类分析等方法，探讨了伏牛山南侧亚热带北界的划分。研究结果表明，该界线大约在拔1000m左右。

| Abstract: | In this paper achievements obtained predecessors about the division between subtropical zone and warm temperate zone on the south side of the Funiu Mountain are firstly summarized, and the cause why these viewpoints about the division are different also have been presented. Seven soil profiles at different hights above sea level are placed and dug along the south side of the Funiu Mountain . Many compositions and properties of these soil humus have been analysed in laboratory. The division between subtropical zone and warm temperate zone on the south side of the Funiu Mountain according to the compositions and properties of soil humus has been made a comprehensive study with mathematical classification method. During the analytic process eights indexes have been used such as altitude?organic carbon ?HA?FA?HA/FA?E4?E6?E4/E6 and so on. The result indecates that the boundary between subtropical zone and warm temperate zone on the south side of the Funiu Mountain is about 1000 metres above sea level. |
