摘要: 以《中国珍稀濒危保护植物名录》、《中国植物红皮书》、《国家重点保护野生植物名录(第一批)》、《中国物种红色名录》、《中国生物多样性红色名录(高等植物卷)》、《内蒙古珍稀濒危保护植物名录》和《内蒙古珍稀濒危植物图谱》中127种内蒙古珍稀濒危植物为研究对象,通过资料收集及专家咨询,构建了内蒙古珍稀濒危植物受威胁等级、优先保护评估体系.建立了濒危系数、遗传价值系数、利用价值系数、生境系数、繁殖系数5项准则,准则下共设17个指标;运用层次分析法确定指标体系权重,计算出珍稀濒危植物濒危等级及优先保护级别.结果表明: 极危种2种、濒危种13种、易危种37种、近危种44种、无危种31种,分别占总数的1.6%、10.2%、29.1%、34.7%、24.4%.其中,受威胁种(极危、濒危和易危种)共52种,占总种数的40.9%.一级保护植物35种、二级保护植物72种、三级保护植物20种,分别占总数的27.6%、56.7%、15.8%.本评估结果与《中国生物多样性红色名录(高等植物卷)》、《内蒙古珍稀濒危保护植物名录》相比,有75种植物的濒危等级和62种植物的保护级别发生了变化.其中新增了9种植物的濒危等级评估和32种植物的保护级别.

Abstract: With 127 rare and endangered plant species of Inner Mongolian in Catalogue of Rare and Endangered Plants in China, China Plant Red Book, National Key Protected Wild Plants List (List No. 1), China Species Red List, Red List of Biodiversity in China: Volume of Higher Plants, List of Rare and Endangered Plants in Inner Mongolia and Atlas of Rare and Endangered Plants in Inner Mongolia as objects, an evaluation system of the threatened grades and conservation priority of rare and endangered plants were built based on data collection and consultation with experts. We set the five criteria, including endangered coefficient, genetic coefficient, utilization coefficient, habitat coefficient, and reproduction coefficient, under which there were 17 subordinate indicators. The analytic hierarchy process was employed to determine the weight of indicators in the system and calculate the endangered grades and conservation priority grades for the rare and endangered species. According to the results of evaluations, two critically endangered (CR) species, 13 endangered (EN) species, 37 vulnerable (VU) species, 44 near threatened (NT) species, and 31 least concern (LC) species were identified, accounting for 1.6%, 10.2%, 29.1%, 34.7% and 24.4% of the total, respectively. Among those species, 52 species were threatened, namely CR, EN and VU species, accounting for 40.9% of the total. The evaluation results of conservation priority grades were: 35 species of Class Ⅰ protected plants, 72 species of Class Ⅱ protected plants, and 20 species of Class Ⅲ protected plants, accounting for 27.6%, 56.7% and 15.8% of the total, respectively. According to the results of evaluation comparison between Red List of Biodiversity in China: Volume of Higher Plants and List of Rare and Endangered Plants in Inner Mongolia, endangered grades of 75 plant species and the protection classes of 62 plant species were calibrated. In this evaluation, the endangered grades of nine plant species and the protection classes of 32 plant species were newly added.
