采用野外调查与室内分析相结合的方法对缙云山不同森林植被下土壤理化性状进行研究.结果表明,不同森林植被覆盖对土壤理化性状有较大的影响.阔叶林下土壤的孔隙度最大,为60.85%±19.04%,针叶林下土壤的孔隙度最小,为52.34%±12.37%.阔叶林下土壤中的碱解氮、速效钾含量明显高于针叶林与针阔混交林;速效磷含量在0~5 cm土层由大到小顺序是阔叶林,针阔混交林,针叶林,但在5~40 cm土层由大到小的顺序却是针叶林,阔叶林,针阔混交林.三种森林植被下土壤有机碳含量随着土层的加深呈现下降的趋势,不同森林植被间土壤有机碳含量由大到小顺序是阔叶林,针叶林,针阔混交林.
Soil physical and chemical properties under different forest vegetations in Jinyun Mountain were studied by field investigation and indoor analysis.The results showed that the coverage of different forest vegetation had a greater impact on soil physical and chemical properties.The porosity of the soil under the broadleaf forest was the largest 60.85% ± 19.04%, and the porosity of coniferous forest was the lowest (52.34% ± 12.37%). The content of available nitrogen and available potassium in the soil under broad-leaved forest was significantly higher than that in coniferous and coniferous and broad-leaved forest. The order of phosphorus content in descending order of 0 ~ 5 cm was broadleaf forest, mixed conifer and broadleaved forest and coniferous forest. However, in descending order of 5 ~ 40 cm soil layer, coniferous forest and broad leaf Forest and coniferous and broad-leaved mixed forest.The content of soil organic carbon under the three kinds of forest vegetation tended to decline with the deepening of soil depth.The order of soil organic carbon content among different forest vegetation was deciduous forest, coniferous forest, needle Mixed forest.
