摘要
本文对油松侧柏混交林生态系统的土壤层、死地被物层、下木和草本植物,以及林木中的营养元素含量,进行了系统的研究.分析和讨论了营养元素在油松和侧柏各器官中含量的分布特点,阐述了油松和侧柏对土壤中营养元素的积聚能力.研究结果可为油松侧柏混交林的经营管理,提供基础数据.
A systematic study has been made on nutrient elements in the soil layer,dead soil covering,underroof layer,herb layer and trees of a mixed forest ecosystem of Pinus tabulaeformis and Platycladus orientalis.The distributing characteristics of nutrient element contents in each organ of Pinus tabulaeformis and Platycladus orientalis have been discussed,and the capacity of Pinus tabulaeformis and Platycladus orientalis for accumulation of nutrient of the mixed forests of Pinus tabulaeformis and Platycladus orientalis has also been discussed.
