| 摘 要： | 研究了黄土高原不同树龄的油松人工林地土壤微生物的分布特征.结果表明：土壤细菌、放线菌和真菌的数量随树龄的变化不显著,而随土壤深度的变化极为显著;细菌数量随土壤深度的变化规律符合Quadratics Ratio模型,放线菌和真菌数量则随土壤深度呈现指数衰减变化.与油松＋紫穗槐混交林、撂荒地相比,油松人工林地土壤细菌含量小于混交林,而大于撂荒地,这为黄土高原地区营造混交林提供了依据.

| Abstract: | The distributive feature of soil microorganism of Pinus tabulaeformis plantation forestland in Loess Plateau of different forest age has been studied.The results shows that quantitive variety of microorganism corresponding with forest age is not remarkable,but very remarkable with soil depth;the variety of bacterism quantity corresponding with soil depth abides by Quadratics Ratio model,the quantitive variety of actinomyces and fungi corresponding with soil depth fit to index function.Compared with the mixed stands of Pinus tabulaeformis and Amorpha fruticoca L.forest and wasteland,the quantity of soil bacterium of Pinus tabulaeformis plantation forestland is more than wasteland,but less than the mixed stands of Pinus tabulaeformis and Amorpha fruticoca L.forest. This laid the foundation for building mixed forest. |
