Investigation Report on Rare and Endangered Eild Plant Resources outside The Nature Reserve of Datong County

本文采用现场考查、文献查阅以及访谈等方法,对大通县北川河源区国家级自然保护地外珍稀濒危野生植物资源进行了调查与分析。共记录了17种珍稀濒危野生植物,分属于13科14属,以龙胆科为主,其中多年生草本占优势。在所调查的植物中,有4种国家Ⅱ级保护植物,13种省级重点保护植物,分别占总数的23.53%和76.47%。通过17种珍稀濒危野生植物的生态因子、生活型、用途的统计,药用植物占总种比69.57%,表明研究区药用植物资源储量较大,经分析发现研究区大部分珍稀濒危野生植物均处于零星分布状态,生存环境面临严重的威胁。本调查结果可为今后该地区珍稀濒危野生植物资源的保护与可持续开发利用提供参考。

By means of field investigation, literature review and interview, this paper investigates and analyzes the rare and endangered wild plant resources outside the National Nature Reserve in Beichuan Heyuan District of Datong County.A total of 17 species of rare and endangered wild plants are recorded, which belong to 13 families and 14 genera, mainly Gentianaceae, in which perennial herbs were dominant.Among the investigated plants, there are 4 species under state II protection and 13 species under provincial key protection, accounting for 23.53% and 76.47% of the total, respectively.According to the statistics of ecological factors, life forms and uses of 17 rare and endangered wild plants, medicinal plants account for 69.57% of the total species, indicating that the medicinal plant resources in the study area are large.Through analysis, it is found that most rare and endangered wild plants in the study area are distributed sporadically, and the living environment is facing a serious threat.The results of this investigation can provide a reference for the protection and sustainable development and utilization of rare and endangered wild plant resources in this area in the future.
