对世界自然遗产地三清山长柄双花木(Disanthus cercidifolius subsp.longipes)优势群落进行了野外调查和分析,结果表明:三清山长柄双花木优势群落为多优势种并存的中亚热带中山常绿阔叶林群落,乔木层的次优势种不明显.长柄双花木是该群落的关键种之一.在植物区系特征上,该群落优势种既具有温带性质又具中亚热带性质,在整体上表现出温带性质和亚热带性质交汇的特点.群落的物种多样性指数和频度指数为:SP=0.92、 SW=4.20、 E=0.94、 E′=0.79.三清山长柄双花木优势群落与江西官山和湖南千家洞长柄双花木群落相比,三地群落存在一定差异,但三清山长柄双花木群落多样性指数和均匀度均高于另两地.三清山和千家洞的长柄双花木群落结构更相似;官山的长柄双花木群落为山地灌丛,群落结构单一,样地中长柄双花木占绝对优势.通过分析三地气象资料和群落特点,表明不同地区长柄双花木群落的差异与年降水量和年平均日照时数相关,而与年平均气温无直接相关关系.
對世界自然遺產地三清山長柄雙花木(Disanthus cercidifolius subsp.longipes)優勢群落進行瞭野外調查和分析,結果錶明:三清山長柄雙花木優勢群落為多優勢種併存的中亞熱帶中山常綠闊葉林群落,喬木層的次優勢種不明顯.長柄雙花木是該群落的關鍵種之一.在植物區繫特徵上,該群落優勢種既具有溫帶性質又具中亞熱帶性質,在整體上錶現齣溫帶性質和亞熱帶性質交彙的特點.群落的物種多樣性指數和頻度指數為:SP=0.92、 SW=4.20、 E=0.94、 E′=0.79.三清山長柄雙花木優勢群落與江西官山和湖南韆傢洞長柄雙花木群落相比,三地群落存在一定差異,但三清山長柄雙花木群落多樣性指數和均勻度均高于另兩地.三清山和韆傢洞的長柄雙花木群落結構更相似;官山的長柄雙花木群落為山地灌叢,群落結構單一,樣地中長柄雙花木佔絕對優勢.通過分析三地氣象資料和群落特點,錶明不同地區長柄雙花木群落的差異與年降水量和年平均日照時數相關,而與年平均氣溫無直接相關關繫.

Based on a field survey and plot data analysis, the characteristics of plant community of Disanthus cercidifolius subsp.longipes from Mountain Sanqingshan of Jiangxi province,China,were studied.The results are as follows:the D.cercidifolius subsp.longipes forest is a mid-subtropical montane evergreen broadleaved community,with multi-dominant plant species,and subdominance of species in the tree layer was not obvious.In terms of floristic composition,this community has temperate property and subtropical property,and shows some transitional characteristics.The Simpson Index of community is 0.92,which the corresponding evenness is 0.94;and the Shannon-Wiener Index is 4.20,which the corresponding evenness is 0.79.Comparing the community of D.cercidifolius subsp.longipes in Mountain Sanqingshan,and those of Mt.Qianjiadong and Guanshan,the community characteristics are different obviously,i.e.the Simpson Index,Shannon-Wiener Index and their evenness in Mt.Sanqingshan are more than those of other two regions.Of course,the constitutes,structure, appearance of communities in Mt.Sanqingshan and Qianjiadong are more similar,which belong to subtropical middle mountain evergreen community.Community in Mt.Guanshan belongs to the mountain shrubs, with a simple structure.Analyzing the meteorological data and features of communities,the difference of D.cercidifolius subsp.longipes community maybe affected by annual precipitation and average annual sunlignt.
