戴云山区竹种资源及其区系的研究

A Study on Bamboo Species Resource and its Flora in Daiyunshan,Fujian Province

通过对戴云山区竹种的调查 ,建立了定位到各乡镇林班或小区的竹种和竹林资源系统 ,计有 12属 6 3种 .茎竿类型以单轴散生型和复轴混生型竹种为主 ,区系地理成分则以东亚成分和热带分布型为主 .这一过渡性质的竹类区系具温带兼少量热带性质 .闽西地区→戴云山区→三明地区→武夷山区的竹类分类群的比较 ,显示出合轴丛生型竹种逐渐减少、单轴散生型竹种先增加后减少、复轴混生型竹种依次递增的规律 ,表明竹类在该地区的分布具有明显的地带性 。

This paper is about the bamboo specie resources including 63 species belonged to 12 genera.They are located in most of villages or sites in Daiyunshan. The dominant rhizome culm types are monopodial scattered and sympodial mixed species,the flora geographical components are clorninatly the Eastern Asia and the Tropical distribution types,this transitional bambusoideae flora are of temperate and slightly tropical character. These rules have been demonstrated through taxonomic comparison from Minxi district to Daiyunshan mountain,Sanming district and Wuyishan mountain,in order that sympodial species gradually decrease, monopodial species decrease after increase while amphipodial species gradually increase, which indicates that bamboo distribution is apparently zonal and that Daiyunshan range is a watershed of notural bamboo specie.
