摘  要：
对太行山低山丘陵区3种植被草丛、灌草丛和刺槐林及土壤养分变化进行了研究。结果表明,3种群落类型Shannon—Wiener指数和丰富度指数均为草丛>灌草丛>刺槐林,总覆盖度草丛>灌草丛>刺槐林。3种植被类型Zn,Mn,Na,Mg,Fe差异不显著。在灌草丛中,Mn,Na,Mg,Fe含量均为下层多于上层,差异均不显著,Zn则上层含量多。但在草丛植被类型中,Mn,Zn,Na含量下层多于上层;Mg,Fe含量上层多于下层。Zn,Mn,Na,Mg,Fe等因子均与有机质无显著相关关系。Mn与其它元素,Fe与其它元素(Na为显著相关),Mg与Na均达到显著相关。

摘  要：
The changes of soil nutrients and three community types (bushes,grass,and Robinia pseudoacacia) in the low mountain and hill district of Taihang Mountains are studied.By Shannon—Wiener index and the richness of the three community types,the communities are in a sequence of grass > shrub bushes > Robinia pseudoacacia and by the total coverage,the sequence is grass> shrub bushes> Robinia pseudoacacia.The contents of Zn,Mn,Na,Mg,and Fe in the three community types have no significant differences.Under the shrub bushes,the contents of Mn,Na,Mg,and Fe in subsoil are more than those in topsoil,but the differences are not significant except Zn.Under grass,the contents of Mn,Zn,and Na in subsoil are more than those in topsoil.Zn,Mn,Na,Mg,Fe,and organic matter are not significantly correlated.Mn and other nutrient elements,Fe and other nutrient elements (Na is significant correlated),as well as Mg and Na are all in extremely significant correlation.
