| 摘 要： | 本文测定了北京百花山山地典型土壤剖面各发生层的有机质含量、腐殖酸组分、可见光谱,利用相关分析方法计算了有机质与海拔高度之间的相关系数。结果表明:有机质与海拔高度的相关系数为0.94,,呈显著相关水平;各剖面土壤腐殖质分析结果表明,该山地土壤的HA/FA值、E4/E6值随着海拔高度的升高而呈现上升趋势。

| Abstract: | Analysis of characteristics of the soils on the Baihua Mountains in the suburbs of Beijing was conducted by determining SOM contents, HA/FA and E4/E6 ratios in soil genetic layers. The results revealed that the SOM, total N and total P were strongly correlated with the altitude. SOM showed a good correlation with the altitude ( r = 0.94). Clay content affected SOM accumulation. |
