摘要
为了探讨低产次生林经过人工择伐改造后林冠下更新红松所形成的异龄阔叶红松林后的生态效益,分别对异龄阔叶红松林、红松纯林以及杂木林3种不同林分类型内土壤的理化性质进行了比较和分析。结果表明异龄阔叶红松林不仅改善了土壤的物理性状,提高了土壤的蓄水能力,而且使土壤有机质、全N、速效P、速效K含量显著提高,对提高土壤肥力和生态效益都有重要意义。
To explore the ecological benefit of uneven age Pinus koreansis forest improved by selective cutting and regenerated under the canopy in the low yield secondary plantations of P. koreansis, the physical and chemical properties of soil in the uneven age broad-leaved plantation of P. koreansis, pure plantation of P. koreansis, and shaw forest were compared and analyzed. The results show that the uneven age P. koreansis plantation not only improves the soil physical properties and increase soil water storage capacity, but also improve the content of soil organic matter, total nitrogen, available P and K, as well as improve soil fertility and ecological benefits.
