摘要/Abstract

摘要： 对福建省建瓯市的杉木(Cunninghamia lanceolata)纯林及3种杉阔混交林的林下植物多样性进行了调查和分析。结果表明:混交林林下灌木层的丰富度指数和Shannon-wienner多样性指数值均大于草本层,除杉木×鹅掌楸混交林外,其他2种混交林草本层的优势度指数值大于灌木层,均匀度指数则是灌木层大于草本层;混交林林下植物种类较少,优势种明显,且分布不均;4种多样性测度指标在不同混交林中差异不大,混交林与杉木纯林差异亦不明显。研究结果可为改进闽北山地杉木纯林及其混交林的培育和经营管理、实现杉木林可持续经营提供参考。

Abstract: In this paper,the undergrowth plant diversity of Cunninghamia lanceolata pure forest,and its three types of mixed forest with 3 species of broadleaved trees in Jian’ou,Fujian province were studied. The results showed that the abundance and Shannon-wienner indexes in all three types of mixed forests were described as shrub layer >herbaceous layer. Except that of Cunninghamia lanceolata×Liriodendron chinense,the Simpson indexes of the 2 other types of mixed forest were greater in the herbaceous layers than that of the shrub layers,Pielou indexes were greater in the shrub layers than the herb layers. The undergrowth plant species of mixed forest was smaller,the dominant species were obvious,and the distribution was uneven. The distinction of four kinds of diversity indexes measured in the different mixed forests was not obvious. Compared with the mixed forest,the difference of all indexes in the pure forest were not significant. The results would help to improve the cultivation and management of Cunninghamia lanceolata and its mixed forest in northern Fujian province,and eventually realize the sustainable management of the Cunninghamia lanceolata forest.
