摘要
于2021—2022年,采用野外调查和查阅相关资料相结合的方法,根据《中国植物物种名录》(2022版),对桫椤科植物在广东的地理分布、分布特征、生境类型和分布区划分进行探讨。结果表明,广东省桫椤科植物共3属10种,约占我国总种数的56%。其中,桫椤、大叶黑桫椤、黑桫椤为广布种,广泛分布于广东省内;粗齿桫椤、小黑桫椤主要分布在粤北地区;结脉黑桫椤主要分布在粤中及粤西地区;平鳞黑桫椤主要分布在粤中地区;中华桫椤和白桫椤仅分布于云开山脉;笔筒树为栽培种,主要分布于广州、深圳和从化。桫椤科植物在广东垂直分布范围约为海拔85—1300 m。桫椤科在广东分布的植被类型可分为:热带季雨林、亚热带常绿季雨林、亚热带常绿阔叶林和沟谷雨林;其地理分布可划分为4个区,分别为粤西、粤北、粤东、粤中地区,其中粤西和粤北地区桫椤科分布种类最丰富。
From 2021 to 2022,the geographical distribution,distribution characteristics,habitat types and distribution area division of Cyatheaceae plants in Guangdong were discussed in accordance with the List of Plant Species in China(2022)by combining field survey and consulting relevant data.The results showed that there were 3 genera and 10 species of Cyatheaceae in Guangdong Province,accounting for 56%of the total species in China.Among them,Alsophila spinulosa,A.gigantea and Gymnosphaera podophylla are widely distributed in Guangdong;A.denticulata and G.metteniana are mainly distributed in northern Guangdong;G.bonii is mainly distributed in central and western Guangdong;G.henryi is mainly distributed in central Guangdong;A.costularia and Sphaeropteris brunoniana are only distributed in Yunkai Mountains;S.lepifera is a cultivated species,mainly distributed in Guangzhou,Shenzhen and Conghua.The vertical distribution range of Cyatheaceae in Guangdong is about 85—1300 m above sea level.The vegetation types of Cyatheaceae in Guangdong can be divided into tropical monsoon forest,subtropical evergreen monsoon forest,subtropical evergreen broad-leaved forest and valley rain forest.Its geographical distribution can be divided into four regions:western Guangdong,northern Guangdong,eastern Guangdong and central Guangdong,of which western and northern Guangdong have the most abundant species of Cyatheaceae.
