摘要: 对伏牛山中段南坡不同海拔高度7个土壤剖面进行了野外调查和室内土壤理化分析,选择土壤氧化物迁移系数、硅铝铁率、活性铁与全铁之比、活性锰与全锰之比、Ba值、β值等指标,运用聚类分析等方法,从土壤物质迁移和积累角度深入探讨了河南省伏牛山南坡亚热带北界的划分。研究结果表明,该界线大约在海拔950m左右。

Abstract: Achievements obtained predecessors about the division between subtropical zone and warm temperate zone on the south side of the Funiu Mountain are summarized in this paper firstly, and the causes why these viewpoints about the division are different also have been discussed. Seven soil profiles studied in this paper are placed along the south side of the Funiu Mountain at different hights above sea level.Many compositions and properties of these soils have been analysed in laboratory. The division between subtropical zone and warm temperate zone on the south side of the Funiu Mountain according to soil material migration and accumulation has been made a thorough study with mathematical classification method. In this analysis twelve indexes have been used such as Kmx, Saf, Ba, β, Feo/Fet, Mno/Mnt and so on. The result indicates that the boundary between subtropical zone and warm temperate zone on the south side of the Funiu Mountain is about 950 metres above sea level.
