摘要/Abstract

摘要： 本文在人工落叶松纯林及人工落叶松与水曲柳混交林的林冠观测数据的基础上建立了落叶松和水曲柳的树冠锥体模型。通过对上述两种森林群落结构的太阳辐射的观测, 利用电磁波的吸收、反射和透射理论分别对以上两种森林群落的光能利用率进行了计算。结果表明理论计算值与实测结果基本一致;双层次混交林的光能利用率高于单层纯林的光能利用率。

关键词: 树冠锥体模型, 太阳辐射, 吸收率

Abstract: Ba on the observed data of the crown structure of artificial Latix olgensis stands and larix olgensis-northeast China ash mixed stands, we established the crown cone model of larix and northeast China ash. By observing the sun radiation in the two forestry communities, from physical basic law of absorbtion, reflection and transmission of electromagnetic wave, we calculate the sunlight utilization ratio of the two forestry communities respectively. and get the result that the sunlight utilization ratio of the double strata mixed stands is larger than that of the one single stratum pure stands.

Key words: Tree-crown model cone, Sun radiation, Absorbtivity
