摘要: 研究了燕山山地华北落叶松人工林3种林分类型植物群落的生物多样性和生物量。结果表明:1)华北落叶松白桦混交林和华北落叶松山杨混交林植物物种数均高于华北落叶松纯林,3种类型群落优势种有很大差异。2)3种类型群落的α多样性指数均表现为草本层>灌木层>乔木层,2种华北落叶松混交林α多样性指数高于华北落叶松纯林。3)华北落叶松纯林乔木层生物量比例最高,达到99.33%,高于两种混交林;各器官生物量的分配规律为树干>树枝>树根>树皮>树叶,且所占比例有所差异。

关键词: 华北落叶松, 生物多样性, 生物量

Abstract: Biodiversity and biomass of plantation community in three different types of Larix princicpis-rupprechtii Mayr.in Yanshan Mountainous Region were studied in this paper.The results showed: (1) The number of plant species of both mixed stand of Larix princicpis-rupprechtii Mayr.and Betula platyphylla Suk.and that of Larix princicpis-rupprechtii Mayr.and Populus davidiana Dode.was higher than the one of Larix princicpis-rupprechtii Mayr.forest.The dominant species were significantly different in three types of plant communities; (2) The order of α biodiversity index of three types of plant communities from high to low was herb layer,shurb layer and tree layer,and α biodiversity index in mixed stand was higher than that of pure stand.(3) In Larix princicpis-rupprechtii Mayr.stand,the propotion of biomass of tree layer was 99.33%,which was higest among three types of plant communities. The order whose allocation of different organ biomass was trunk> branches> root> bark> leaves,and the propotion of each organ in the whole biomass was different.

Key words: Larix princicpis-rupprechtii Mayr, biodiversity, biomass
