| 摘 要： | <正>福建北部山区地处中亚热带常绿阔叶林带,气候温暖湿润,四季明显,雨量充沛,为许多阔叶树适生环境。现存大量原生植被,其中著名的武夷山自然保护区和“万木林”自然保护区植被都较为完整,同时该地区的植被起源古老,还存在着较为丰富的第三世纪和第四世纪以前的古老科属和子遗植物,以及种类繁多的阔叶树种。笔者认为对植被调查的主要目的之一,是根据相似性原理摄取对营造人工林有用的信息,指导现实的生产。基于这种想法,笔者对古老、丰富、繁多的闽北天然阔叶林进行了分析,用数学手段确定闽北阔叶树种的生态组,从自然群落中摄取,提炼出有用的信息。

FUZZY CLUSTER ANALYSIS OF ECOLOGICAL GROUP OF DECIDUOUS TREES IN THE NORTH FUJIAN |
| |
| Abstract: | This paper deals with the classification of the natural decidurous tree in the north Fujian by means of Fuzzy cluster analysis, and as a result, six ecological groups are given to the studies trees. They are Castanopsis sclero-phylla + Quercus glauca, Elaeocarpus chinensis + Ormosia xylocarpa, Castanopsis fabri +Albizzia kalkora, Adinandra millettii + Vaccinium bracteatum, Schima superba + Castanopsis eyrei, Castanopsis kawakamii + Dendropanax dentiger.The result basically tallies with the natural situation. These ecological groups provide an important basis for the plantation of mixed decidurous forest.Some questions occured in calculation are also discussed. |
