【摘要】 在鸡公山国家级自然保护区的森林环境中,于立地条件相似的情况下设置4个调查样地,分别采集土样测定其土壤理化性质,对数据进行对比分析。结果表明:针阔混交林土壤紧实程度较高,有利于抵抗径流的冲刷,而裸露地抵抗径流的冲刷能力相对较小;4种林分类型中落叶阔叶林土壤肥力相对较好;人为因素对森林土壤的影响十分长远。更多还原

【Abstract】 Four sample plots with similar site conditions were set in Jigongshan National Nature Reserve for collecting soil samples for determining the soil physical and chemical properties.The study results are as follows:needle mixed forest soil compaction degree is higher,which is beneficial to the resistance of the scour,the resistance of the runoff bare scour capability is relatively small and four kinds of forest types of deciduous broadleaved forest soil fertility relatively better.The influence of human factors on the forest soil is a long-term one.更多还原
