通过研究表明 ,我省竹亚科植物 9属 51种 ,因受南北两地地形及气候的地带性因素的影响 ,形成竹类分布特点是南多北少 ,物种由喜温性转为耐寒性。其区系成分 ,全球性是亚洲热带、亚热带的东南和东亚成分明显 ,国内以华东成分为主 ,依次是西南及华南近等 ,华北及西北亲缘关系较疏远 ,但华北的河南省与我省的淮北平原关系十分密切 ,共有率达 10 0 % ,而河北省仅有 13%。
WT5BZ]After field investigation, it is found that bamboo resource is abundant in Anhui province. It consists of 51 species including varieties and forms belonging to 9 genera. Because of the great differences in topography and climatic features between the south and north part of Anhui province, the number of bamboo species is distributed unevenly, most of them concentrated in the south of Yangtze River with warm tolerant nature and less number with cold resistant nature in the north of Huai River. In regard to the characteristics of the floristic elements in this region, it falls into category of tropical and subtropical floras of Southeast and East Asia. Within the sphere of our country, the provincial bamboo florstic elements mainly belong to the flora of East China, and with nearly the equal number of the elements belongs to the flora of South China and Southwest China, and less related to the flora of North and Northwest China. However, the bamboo flora of Henan province of North China is in close relationship with the flora of Huaibei plain of Anhui. It both shares the element rate of 100%, while sharing only 13% in Hebei province. [WT5HZ]
