摘要: 依据国家林业和草原局、农业农村部2021年9月发布的《国家重点保护野生植物名录》,查阅中国科学院华南植物园标本馆(IBSC)、华南农业大学林学与风景园林学院树木标本室(CANT)、中国数字植物标本馆(CVH)等馆藏标本,以及相关文献,结合近年来的野外调查记录,整理出新版广东省国家重点保护野生植物名录及地理分布数据,利用ArcGIS软件,对其分布格局进行分析。结果显示,广东省国家重点保护野生植物共57科87属164种(9变种2亚种),其中苔藓植物2科2属2种,石松类和蕨类植物8科11属24种,种子植物46科73属137种9变种2亚种,10种为一级保护植物,13种为广东特有植物。兰科(36种)和豆科(22种)的重点保护野生植物种类较多,集中在红豆属(17种)、石斛属(13种)、兰属(9种)等。地理分布方面,依据保护植物种数排序,依次为粤北(126种)、珠三角(104种)、粤西(91种)、粤东(33种);粤北地区以乳源最为丰富(64种);粤西地区以信宜、阳春最丰富,分别为51种和50种;珠三角地区以广州最丰富(48种);粤东地区保护植物较少,所有县市均未超过25种。文中提供的2021年版广东省国家重点保护野生植物名录及其分布记录,可为广东省自然保护地和森林公园的科学考察、保护地规划、就地保护和迁地保护等提供参考。

Abstract: Based on the List of State Key Protected Wild Plants released by National Forestry and Grassland Administration and Ministry of Agriculture and Rural Affairs of China in September 2021, the herbarium records of the key protected plants were checked in South China Botanical Garden of the Chinese Academy of Sciences (IBSC), South China Agricultural University (CANT) and Chinese Virtual Herbarium (CVH). The related literature and wild survey records in recent years were reviewed to compile the new list of Guangdong key protected wild plants. The distribution patterns of these plants were also analyzed. The results showed that there were key protected wild plants 164 species (9 varieties and 2 subspecies) belonging to 57 families and 87 genera in Guangdong province, including 2 families, 2 genera and 2 species of Bryophytes, 8 families, 11 genera and 24 species of Lycophytes and Ferns, 46 families, 73 genera and 137 species (9 varieties and 2 subspecies) of Spermatophytes. Ten species are primary protected plants and 13 species are endemic to Guangdong. The largest number family of these key protected plants is Orchidaceae (36 species), followed by Fabaceae (22 species), including Ormosia (17 species), Dendrobium (13 species), Cymbidium (9 species). The distribution patterns showed the district ranking of species richness (Northern Guangdong > Pearl River Delta> Western Guangdong > Eastern Guangdong) and three diversity centers of protected species. In northern Guangdong, Ruyuan county is the most abundant (64 key protected species); in western Guangdong, Xinyi and Yangchun county are the most abundant, with 51 and 50 key protected species respectively; in the Pearl River Delta, Guangzhou is the most abundant (48 key protected species); and only a few protected plants are distributed in eastern Guangdong, with all counties and cities less than 25 species. The list of the key protected species will provide detailed reference for the scientific investigation, conservation planning, in situ and ex situ conservation of nature reserves and forest parks in Guangdong province.
