摘要
为了解广西马山县野生种子植物区系特征,对其野生种子植物资源展开调查。结果表明:马山县有野生种子植物1504种,隶属于170科740属,以被子植物占优,裸子植物较贫乏。从科属组成看,以单种科、寡种属为主体,而种子植物属和种则集中在中大型科、小属和单种属内。植物分布区类型较丰富,热带性质明显并具有一定温带成分,呈热带至亚热带过渡性质。与邻近地区比较,马山县植物多样性较丰富,植物区系与广西宾阳县最相近。总体而言,马山县植物多样性丰富,热带成分显著,生活型丰富并以草本植物为主,区系古老与年青并存,特有现象突出,整体呈现出北部湾植物区系特征。
In order to understand the flora characteristics of wild seed plants in Mashan county,Guangxi,the wild seed plant resources were investigated.The results showed that there were 1504 species of wild seed plants in Mashan county,Guangxi,belonging to 170 families and 740 genera.Angiosperms were dominant and gymnosperms were relatively scarce.From the perspective of family and genus composition,monospecific families and oligospecies were the main body,while the genera and species of seed plants were concentrated in medium and large families,small genera and monospecific genera.The plant distribution area was rich in types,with obvious tropical nature and certain temperate components,showing a transitional nature from tropical to subtropical.Compared with neighboring areas,Mashan county has richer plant diversity,and its flora is the closest to Binyang county,Guangxi.In general,Mashan county is rich in plant diversity,with prominent tropical components,rich in life and mainly herbaceous plants,with ancient and young flora coexisting,and the unique phenomenon is prominent,reflecting the characteristics of the flora of the Beibu Gulf as a whole.
