摘要:

掌握重点保护野生植物的濒危现状及评估濒危等级是制定科学保护策略的关键。根据江苏第二次重点保护野生植物资源调查(2012-2018)以及近年来相关调查资料, 我们采用世界自然保护联盟(IUCN)物种红色名录的濒危等级与评估标准, 对江苏分布的珍稀濒危植物的现状与濒危等级进行了评估与分析。结果表明: (1)江苏41种国家重点保护和濒危野生植物的濒危等级可以分为7个等级。包括地区灭绝(RE) 2种, 占总种数的4.88%; 极危(CR) 10种, 占24.39%; 濒危(EN) 6种, 占14.63%; 易危(VU) 13种, 占31.71%; 近危(NT) 2种, 占4.88%; 无危(LC) 2种, 占4.88%; 数据缺乏(DD) 6种, 占14.63%。其中, 受威胁物种(包括CR、EN和VU)有29种, 占总种数的70.73%。(2)建议的江苏重点保护野生植物有74种, 隶属于40科62属; 它们的受威胁比例较高, 达74.32%。江苏人口众多、环境资源压力较大, 近年来生产经营和土地利用方式的改变以及宣传教育不足很可能是导致这些原生物种濒危的主要原因。因此建议: (1)尽快制定江苏省级重点保护野生植物名录; (2)加强科学研究, 同时对部分濒危植物进行就地保护和迁地保护, 积极开展野外回归、近地保护和动态监测; (3)继续加大对重点保护野生植物的保护管理和宣传力度。

Abstract

Aims: It is crucial to assess the endangered category for national key protected and endangered wild plants when making scientific protection strategies. The purpose of this study is to identify the diversity, species distribution, and threatened degree of rare and endangered plants in Jiangsu Province, China.

Methods: Based on the data from the second survey of protected wild plant resources in Jiangsu Province (2012-2018) and related investigations in recent years, we examined species diversity and evaluated the threatened status of these endangered species in light of the IUCN Red List Category and Criteria (2012).

Results: The results showed that: (1) 41 endangered species belonged to national key protected and endangered wild plants in Jiangsu, and they could be divided into 7 categories. There were 2 species of Regional Extinction (RE), accounting for 4.88% of the total species. There were 10 Critically Endangered (CR) species, 6 Endangered (EN), 13 Vulnerable (VU), 2 Near Threatened (NT), 2 Least Concern (LC), and 6 Data Deficiency (DD), accounting for 24.39%, 14.63%, 31.71%, 4.88%, 4.88%, and 14.63% of the total species, respectively. The majority of them fell into threatened species, including CR, EN, and VU, accounting for 70.73% of the total species. (2) It was suggested that 74 species of wild plants belonging to 62 genera and 40 families should be protected in Jiangsu Province. The majority of them were endangered species, up to 74.32%. The high number of endangered species may be primarily ascribed to tremendous environmental pressure resulting from high human populations in Jiangsu, changes in production practices and land use patterns in the past decades, and low awareness of environmental publicity and education.

Conclusion: We propose: (1) to formulate the list of provincial key protected wild plants in Jiangsu Province as soon as possible; (2) to strengthen scientific research, by combing in situ and ex situ conservation for some critically endangered species, by carrying out reintroduction, near situ conservation and dynamic monitoring; (3) to enhance public awareness of biodiversity, protection, and management.
