江西安福武功山木本植物区系的研究

A STUDY ON THE WOODY FLORA OF WUGONG MOUNTAINS IN ANFU COUNTY,JIANGXI PROVINCE

武功山地形复杂,自然条件优越,植物种类丰富.为了研究该地区木本植物区系,作者三赴安福县进行调查,共采集到木本植物标本1300余号,经鉴定整理表明,安福武功山木本植物区系具有较典型的华东地区中亚热带植物区系的特征.本文论述了武功山木本植物区系的基本特点,分析了树木资源状况,描述了主要森林植被类型,最后提出了关于保护珍稀树木、改善生态环境、维护生态平衡以及合理开发利用森林资源的建议和措施.

This paper is to study the woody flora of Wugong Mountains situated at 114°04′-114°28′E,27°16′-27°34′N in Anfu county,Jiangxi Province.Jinding,the highest peakof the mountains (1918.3 m above the sea level),is also a main peak in this province.Byidentifying and sorting out the specimens collected during field surveying,it can.be con-cluded that though the primeval vegetations have almost all disappeared,the woody flora,protected by the varied topography and moistened by the advantageous subtropical mon-soon climate,is a typical one in the region.The floristic characteristics are chiefly shown asfollows:(1)Plentiful woody plants:at least.733 species and varieties,belonging to 281 gen-era,105 families,are distributed here.(2)Complex geographic composition:14 areal typesout of the whole 15 ones in China have appeared.(3)The ancient origin of the composition:(a)it possesses many original taxa;(b)besides 43 genera of two disjunct distributions,manyplants in other distributions are also distributed disjunctly;and(c)the monomorphic andoligomorphic genera are abundant.(4)Large proportion of the endangered plants:most of the pecious-and-rare,the endemic,and some other species are on the verge of disappearing in this area.Laurilignosa,the zonai one among the six main forest forms,chieflyconsists of the evergreen trees of Fagaceae,Lauraceae,Elaeocarpaceae,Theaceae,ect.Toprotect the endangered species,maintain the ecological balance,and explore the rich forest resources rationally,some suggestions are made in the paper for reference.
