摘要
为加强对罗霄山脉地区珍稀濒危植物的保护和管理,作者在对该区域的植被和植物区系全面调查的基础上,针对珍稀濒危植物的组成、种群数量、生存状态等进行了深入调查和评估。结果表明:(1)整体上,罗霄山脉各类珍稀濒危植物共59科142属279种,其中:被IUCN红色名录收录17种,包括极危种(CR) 2种,濒危种(EN) 3种,易危种(VU) 12种;被《中国生物多样性红色名录:高等植物卷》收录的共105种,包括极危种9种,濒危种33种,易危种63种;被《国家重点保护野生植物名录》收录的共257种,包括Ⅰ级8种,即银杏(Ginkgo biloba)、资源冷杉(Abies beshanensis var.ziyuanensis)、南方红豆杉(Taxus wallichiana var.mairei)、莼菜(Brasenia schreberi)、伯乐树(Bretschneidera sinensis)、细叶石斛(Dendrobium hancockii)、铁皮石斛(D. officinale)、细茎石斛(D. moniliforme)等, II级249种;被CITES收录的有71种。(2)在局部区域,罗霄山脉自北至南由5条中型山脉组成,其珍稀濒危植物的数量分布由北向南呈现梯级变化,显示出与该地区植被和植物区系的丰富度和保存状况密切相关,其中幕阜山脉147种、九岭山脉138种、武功山脉133种、万洋山脉207种、诸广山脉192种。(3)从珍稀濒危植物属种组成看,保存有大量古老、孑遗和特有的类群,并且受到气候和地理环境的影响,其中有单型属19属,中国特有种129种。本文针对各珍稀濒危植物的生存现状,提出了按分布区域和濒危性质进行群落监测或适度进行人工干预等保护措施。
In order to strengthen the protection and management of rare and endangered plants in the Luoxiao Mountains, we made extensive investigations on the species composition, population size, and survival status of the rare and endangered plants based on vegetation and floristic surveys. The results are as follows:(1) A total of 279 rare and endangered plant species from 142 genera and 59 families were recorded in the Luoxiao Mountains. Among them, 17 species were included in the IUCN Red List, i.e. 2 critical species(CR), 3 endangered species(EN), and 12 vulnerable species(VU);and 105 species were included in the China Biodiversity Red List: Higher Plants, i.e. 9 critical species, 33 endangered species, 63 vulnerable species;257species in the National Key Protected Wild Plants List, i.e. Grade I 8 species, i.e. Ginkgo biloba, Abies beshanensis var. ziyuanensis, Taxus wallichiana var. mairei, Brasenia schreberi, Bretschneidera sinensis, Dendrobium hancockii, D. officinale, and D. moniliforme, and Grade II 249 species;71 species were listed in Appendix II of CITES.(2) The Luoxiao Mountains are composed of five medium-sized mountains, and across these mountains, the number of rare and endangered plants changed from north to south, indicating that their survival status was closely related to the species richness and the preservation of vegetation and flora in the areas. Mt. Mufu had 147 species, Mt. Jiuling 138 species, Mt. Wugong 133 species, Mt. Wanyang 227 species, and Mt. Zhuguang 192 species.(3) According to the species composition of rare and endangered plants, there were a large number of ancient, relict and endemic taxa, which are affected by climate and geographical environment, including 19 monotypic genera and 129 species endemic to China. According to the survival status, and distribution of rare and endangered species, this paper puts forward some protection measures, such as community monitoring or appropriate artificial intervention, etc.
