  • 摘要: 土壤有机质在森林生态系统中具有重要作用, 是估算土壤碳储量、评价土壤肥力和质量的重要指标。本文利用已发表文献中的数据, 从省域尺度上分析了杉木人工林土壤有机质的分布特征及其对土壤养分含量的影响, 为杉木(Cunninghamia lanceolata)人工林可持续经营提供理论依据。本文以文献中广东、广西、湖南、江西、浙江、福建6省22个林场1092个研究数据为基础, 分析了我国杉木人工林主产区表层(0~20 cm)土壤有机质含量特征、对土壤类型和地形等的响应及其对土壤养分的影响。结果显示, 杉木人工林表层土壤有机质平均含量为(31.02±13.44) g·kg−1, 养分等级为中, 变异系数为43.33%, 属中等变异水平; 有效磷含量为(5.41±8.01) mg·kg−1, 养分等级为富, 属高度变异, 变异系数为148.06%; 全磷含量(0.49±0.38) g·kg−1, 养分等级为极贫, 变异系数为77.55%, 属中等变异。不同土壤类型有机质含量差异较大, 山地黄壤的含量最高, 为(46.63±16.88) g·kg−1, 暗红壤最低, 为(15.81±4.38) g·kg−1。林分密度、海拔、坡度和土壤pH是杉木人工林表土有机质含量变化的主要影响因素, 相对贡献量分别为−0.35、0.28、0.11和0.11。土壤有机质对全氮、有效氮、全钾、有效钾的贡献程度较高, 相对贡献量分别为0.17、0.47、0.16和0.21。结果表明: 杉木人工林表层土壤有机质的养分等级为中。从样本量占比区间来看, 杉木人工林表层土壤有机质分布等级较为集中, 主要分级表现出“多中下, 少富级, 无极贫”的分布特征。海拔、坡度和土壤pH对土壤有机质含量变化的影响表现出明显的正效应, 林分密度则为负效应; 土壤有机质对土壤全氮、有效氮、全钾、有效钾含量有较明显的正面促进作用, 对全磷具有微弱的负面影响。
