摘要:为了厘清内蒙古自治区国家重点保护植物的县域分布、受威胁程度以及保护现状,并使其能够得到更加全面的保护,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》,根据野外调查记录和标本采集,并查阅内蒙古大学标本馆(HIMC)、中国数字植物标本馆(CVH)等馆藏标本,以及相关文献,整理出内蒙古自治区国家重点保护野生植物县级分布数据,并予以分析和评价。结果显示,内蒙古国家重点保护野生植物共48 种,数据缺乏(DD)的有1 种,濒危(EN)的有10 种,易危(VU)的有19 种,近危(NT)的有10种,无危(LC)的有8 种。其中低等植物3 种,高等植物45 种;重点保护的高等植物占内蒙古高等植物的1.4%(45/3205),其中苔藓植物占0.2%(1/586)、裸子植物占4%(1/25)、被子植物占1.6%(43/2619)。在县域分布上,阿拉善左旗分布最多(15种),其次为鄂伦春自治旗(13 种)、牙克石市(12 种),克什克腾旗(11 种),阿拉善右旗(10 种)、额尔古纳市(10 种),其余旗县分布的国家重点保护植物均小于10 种。44 种国家重点保护野生植物在现有自然保护区中得到不同程度的保护,其中仅在国家级自然保护区有分布记录的有12种,仅在自治区级自然保护区有分布记录的有4 种,在国家级保护区和自治区级保护区均有分布的有28种;有4种植物未受到自然保护区的保护。基于上述结果,对内蒙古国家重点保护植物今后的监测及保护提出了对策和建议。 |

Abstract: This study explore the county-level distribution, threat degree and conservation status of national key protected plants in Inner Mongolia based on the field survey records and specimen collection, and refer to the Inner Mongolia university(HIMC), Chinese Virtual Herbarium (CVH). The results showed that there were 48 key protected wild plant species, including 1 species with data deficiency (DD) , 10 species in endangered (EN), 19 species in vulnerable condition (VU), 10 species in near threatened (NT) and 8 species not at risk (LC). There are 3 lower plant species and 45 higher plant species. The key protected higher plants account for 1.4% (45/3205) of Inner Mongolia's higher plants, with moss plants accounting for 0.2% (1/586), lycophytes and ferns accounting for 0.0% (0/68), gymnosperms accounting for 4% (1/25), and angiosperms accounting for 1.6% (43/2619). In terms of county-level distribution, Alxa Left Banner has the highest number of species (15 species), followed by Oroqen Autonomous Banner (13 species), Yakeshi (12 species), Kashigteng Banner (11 species), Alxa Right Banner (10 species) and Erguna City (10 species). The number of nationally protected plants distributed in other counties is less than 10 species. There are 44 of 48 wild plants under state key protection are protected in existing nature reserves; among them, 12 are only distributed in national nature reserves, 4 are only distributed in autonomous region level nature reserves, 28 are distributed in both national reserves and autonomous region level reserves, and 4 plants are not protected by nature reserves. Based on the above results, we have put forward suggestions for the future monitoring and protection of the national key protected plants in Inner Mongolia. |
