    摘要:

    探讨了广东省车八岭国家级自然保护区原生阔叶林,次生阔叶林,马尾松针阔混交林,马尾松纯林及次生草坡等5个不同演替阶段植物落的土壤理化性质的特点。初步结果显示,不同演替类型的植被,其土壤理化性质有一定差异,原生林的土壤结构和土壤肥力比较好,土壤有机质,全氮,有效磷和有效钾都比较高;

    Abstract:

    Soil characteristics of 5 different successional types of vegetation in Chebaling National Nature Reserve, Guangdong Province were investigated. The preliminary results showed that the soil characteristics varied greatly with different sites. In general, the intact forest possessed higher content of organic matters, total nitrogen, available phosphorus and available potassium. As compared with the other broadleaved forest, the secondary grassland dominated by Miscanthus floridulus and Imperata cylindrica were lower in available phosphorus and total nitrogen, but higher in available potassium and pH value. The pine woodland were lower in organic matters and available potassium, but higher in available phosphorus than other vegetational types.
