| 摘 要： | 在土壤性质分析的基础上,应用丰富度、多样性、相似度指标,研究了火烧迹地植被恢复情况,并与未过火林地做出了比较,讨论了北京西山地区火烧迹地土壤性质的变化与植被恢复之间的关系。结果表明:1)火烧迹地土壤的土粒密度增加,pH值呈上升趋势,土壤有机质减少,全氮增加,有机质的C/N比值在15左右。2)火烧迹地上植被的物种丰富度、Simpson指数、Shannon-Wiener指数高于未过火林地,火烧迹地与未过火林地更新层的物种丰富度相差不大,灌木层和草本层的物种丰富度和多样性则是火烧迹地上较高。3)火烧迹地与未过火林地土壤性质的差异导致了植被的差异,植被恢复也对土壤性质的变化产生了影响。

| Abstract: | On the basis of the analysis of the soil properties,richness,species diversity and Jaccard index are used to research the relations between the properties of soil variation and vegetation restoration in the burned areas of Beijing Xishan.The conditions of vegetation restoration in the burned areas are studied and compared with the natural regeneration.The result showed that:1)in burned area,soil particle density increases,soil pH value is on the upward trend,the content of organic matter reduces but N increases,the C/N of organic matter reaches 15.2)the species richness,Simpson,Shannon-Wiener index of plant on the forest soil where fire has happened are higher than unburnt area.In burned area,the richness of arbor and shrub is nearly no different to unburnt area,but the richness and diversity of Herbage and shrubs is higher.3)the difference of soil properties between burnt area and unburnt area leads to the difference of vegetation,and at the same time,vegetation restoration has an effect on the variation of soil property. |
