【摘要】 从林木生长及其与生态环境之间相互关系入手,对杉木枫香混交林与枫香、杉木纯林进行了定位调查研究。结果表明:混交林生长优势明显,有利于地力的维持和形成稳定的人工林群落。改善了林内的小气候条件和土壤的理化性状,是一种高产稳定、生态协调的人工针阔混交林类型,与杉木纯林相比,11年生混交林蓄积提高34.8%,土壤有机质含量增加43.3%,含氮量增加12.1%,速效氮、磷、钾含量分别增加11.5%、8.3%和11.3%。营造杉木枫香混交林是杉木纯林皆伐迹地更新,防治地力衰退的有效途径之一。更多还原

【Abstract】 The mixed plantation of Cunninghamia lanceolata and Liquidambar formosana was positioned and investigated based on its growth and interaction with ecological environment.The results showed the mixed plantation had obvious predominance in its growth and was beneficial to maintain soil fertility and to form a steady plantation community.It was a high-yield,steady and ecological harmonious mixed plantation of conifer and broadleaf.Compared to pure plantation of Cunninghamia lanceolata,11 year-old mixed plantation had 34.8% increment in volume,43.3% increment in soil organic substance,12.1% increment in nitrogen,and had 11.5%、8.3% and 11.3% increment in available introgen,phosphate and potassium,respectively.To establish a mixed plantation of Cunninghamia lanceolata and Liquidambar formosana is an effecive approach for regeneration in clean-cutting land in pure plantation of Cunninghamia lanceolata and for preventing soil productivity decline.更多还原
