The preliminary study indicates that the nutrient concentration of throughfall has increased obviously in man-made forests of Cunninghamia lanceolata and Pinus massoniana as compared with rainfall in adjacent openning. The relative abundance of nutrient content for precipitation was N>Ca>K> Mg>P. The relative abundance of nutrient content for throughfall was K> N>Ca>Mg>P. The total amount of nutrient input with rainfall in two stands account for 48-53% of total nutrient returns. More amounts of N, K, Mg were...

The preliminary study indicates that the nutrient concentration of throughfall has increased obviously in man-made forests of Cunninghamia lanceolata and Pinus massoniana as compared with rainfall in adjacent openning. The relative abundance of nutrient content for precipitation was N>Ca>K> Mg>P. The relative abundance of nutrient content for throughfall was K> N>Ca>Mg>P. The total amount of nutrient input with rainfall in two stands account for 48-53% of total nutrient returns. More amounts of N, K, Mg were transferred to the soil through throughfall than litterfall while more Ca and P were added to the soil through litterfall. Nutrient return approximates precipitation closely in a semi-log curve, indicating a limited and gradual supply of nutrients from their respective sources between the intervals of rain.

本文对杉木和马尾松林内、外雨树干茎流及迳流所含各种养分物质量进行了测定,其结果表明:林内雨的各种养分物质浓度显著地高于林外雨。林外雨的各养分物质含量是 N>Ca>K>Mg>P,杉木林内雨的各种养分物质量是 K>N>Ca>Mg>P。皆伐迹地迳流中养分流失量显著地高于林地的流失量。雨水养分含量与降雨量存在着半对数函数关系。由降雨输入的养分量显著地大于迳流输出的养分量。林内雨和树干茎流淋溶的养分量占还原养分总量的 48—53%。林内雨和树干淋溶的K、Mg、N的养分量超过凋落物归还的养分量。

Pinus tabulaeformis Carr and Robinia pseudoacacia L. are main planting trees in Loess Plateau of China. According to the characteristics of reinforcement of tree roots to soil the measure method of pulling single root out, combined with investigating root parameters in the forest land, is desigened, and by which the reinforcement of P.tabulaeformis and R.pseu doacacia roots to soil are estimated. It was showed that: (1)the reinforcement of a single root appears the relation of power function with the root diameter; (2)the reinforcement of P.tabulaeformis and R.pseudoacacia roots increase rapidly with the forest stand age. After 15 years of planting, the increasing rate of R.pseudoacacia roots reinforcement slow down, but that of P.tabulaeformis roots keeps normal still; (3)the reinforcement of two stands in any ages decrease gradually with soil depth.At the same stand ages, the reinforcement of R.pseudoacacia roots at any depth is higher than that of P.tabulaeformis. In addition, the reinforcement depth of R.pseudoacacia root is deeper than that of P.tabulaeformis.

本文提出了一种用于定量研究乔木树种林木根系固土作用的方法,并用此方法对人工刺槐和油松纯林林木根系的固土作用进行研究,分別找到了两个树种的单根固持力与根径之间的关系,得到了它们的回归方程式。利用对不同林龄林分林地各层深根参数的调查资料,并借助单根固持力与根一径关系方程式,分别估算了两个林分几个林龄梯度对林地各层深土的固持力。结果表明,两种林分对林地土壤的固持力均随林龄的增长而增大,刺槐林固持土壤的深度亦远远超过油松林。根据研究结果,对山西省吉县红旗林场不同年龄的人工刺槐林和油松林的固土作用作出了定量描述和价评。
