    摘要:

    该研究以《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》受威胁种、《中国生物多样性红色名录——高等植物卷(2013)》受威胁种、《内蒙古珍稀濒危保护植物名录》以及《内蒙古珍稀濒危植物图谱》中的内蒙古部分为初始数据,并对其名称、拉丁学名、科属的归属问题等做了一系列的修定和完善,最终确定127种珍稀濒危植物为研究对象。通过系统收集、整理不同学者对内蒙古珍稀濒危植物相关文献资料的研究成果及数据,进行野外实地调查和标本采集,对内蒙古珍稀濒危植物地理分布、区系组成及特征进行分析。结果表明:(1)内蒙古珍稀濒危植物共53科、103属、127种,其中蕨类植物1种,裸子植物3科5属9种,被子植物49科97属117种。(2)内蒙古珍稀濒危植物在全区东、西阿拉善州、贺兰山州以及兴安北部州分布较多,仅分布于一个州的物种有59种,占总种数的46.46%。(3)内蒙古珍稀濒危植物的垂直分布格局呈单峰型,在海拔1 000~1 600 m之间的植物种数最多。(4)内蒙古珍稀濒危植物中豆科、菊科和毛茛科植物最多,单种属有35属。(5)内蒙古珍稀濒危植物的区系成分以温带分布型比例最高,起源古老,孑遗植物较多,草本和中生植物比例最大,与内蒙古植物区系特征相似。

    Abstract:

    In this study, we took the data of the Inner Mongolia part in The Catalogue of Rare and Endangered Plants in China, The China Plant Red Book, The National Key Protected Wild Plants List (List No.1), the threatened species in The China Species Red List, the threatened species in The Red List of Chinese BiodiversityThe volume of Higher Plants (2013), The Catalogue of Rare and Endangered Plants in Inner Mongolia and Recorded Illustration of Rare and Endangered Plants in Inner Mongolia as initial data, and performed a series of revision and perfection to the name, latin name, attribution of families and genera and other problems. Eventually, we confirmed 127 rare and endangered plant species as objects of the study. During our systematic collecting and organizing of the research results and data of different scholars on relevant documents of rare and endangered plants in Inner Mongolia, we also conducted field investigation and specimen collection, the geographic distribution and features of flora of plants were analyzed in this area. Results showed that:(1) there are 127 rare and endangered plants, 103 genera and 53 families in Inner Mongolia, among which, pteridophyte covers 1 species; gymnosperm 3 families 5 genera and 9 species; angiosperm 49 families 97 genera and 117 species.(2) East and West Alashan state, Helan Mountain state and Xingan North State share more distribution of the rare and endangered plants in Inner Mongolia, each taking up to 59 species, 46.46% of the total number.(3)The vertical distribution pattern of rare and endangered plants in Inner Mongolia presents an unimodal form, with the largest amount of plant species between 1 000 and 1 600 meters. (4) Among the rare and endangered plants in Inner Mongolia, the number of Leguminosae, Compositae and Ranunculaceae species ranks top, 35 monotypic genera. (5) As for the rare and endangered plants in Inner Mongolia floristic elements, temperate distribution has the highest proportion, with ancient origin, there are many relic plants, while herb and mesophytes enjoy the largest proportion, similar to the floristic characteristics of Inner Mongolia. The aim of the research is to perform a series of revision and perfection to the list of rare and endangered plants in Inner Mongolia.
