宝天曼自然保护区珍稀濒危植物研究

Study on Rare and Endangered Plants in Baotianman Nature Reserve

依据《国家重点保护野生植物目录(第1批)》、《中国红皮书》(第1册)和《河南省珍稀濒危植物保护名录》,结合前人研究成果,系统研究宝天曼自然保护区珍稀濒危植物种类、科属分布、区系特征、生活型及其与相邻自然保护区的相似度,并提出切实可行的保育恢复措施。结果表明,宝天曼自然保护区国家级和省级珍稀濒危植物达105种,隶属46科74属;区系特征呈现出明显的温带性质;生活型以落叶乔木和多年生草本为主;与相邻保护区的相似度较低,有其独特的地理优势和保护价值。

According to National Important Wild Conservation Plant List（List 1）,Red Book of Plants in China（Vol.1） and Henan Important Wild Conservation Plant List,combined with former research results,the species,family and genera distribution,flora characteristics,growth-type and its similarity degree with neighbor nature reserve of endangered plants in Baotianman Nature Reserve were investigated and analyzed.And measurements for protecting rare and endangered plants in Baotianman Nature Reserve were proposed.The results showed that Baotianman Nature Reserve had 105 species of rare and endangered plants,which belongs to 46 families 74 genera.The floristic elements had obvious temperate characteristics.Deciduous tree and perennial herb were in the majority as far as plant growth-type concerned.The similarity was low between Baotianman and neighbor nature reserve in Henan.
