大兴安岭地区濒危植物东北岩高兰研究进展与保护

Research Progress and Protection of the Endangered Plant Empetrum nigrum in the Greater Xing'an Mountains

珍惜濒危植物东北岩高兰在大兴安岭地区呈零星分布,主要集中于亚高山矮曲林带,生长在碎石块裸露的山顶部,其自身繁殖比较困难,导致东北岩高兰濒临灭绝。东北岩高兰的药用价值极高,是少数能够在重金属污染区生存的物种,对维护生物多样性及环境的保护有重要意义。在综述国内外研究文献基础上,对黑龙江大兴安岭地区内东北岩高兰的保护现状进行调查分析,分析得出本区域东北岩高兰具有典型性、脆弱性和多样性的特点,并提出了保护对策。

The rare and endangered plant Empetrum nigrum is distributed sporadically in the Greater Khingan Mountains.It is mainly concentrated in the subalpine dwarf forest belt.It grows on the top of the mountain with bare rocks.It is difficult to reproduce on its own,which makes the Empetrum nigrum endangered.The Empetrum nigrum has a very high medicinal value.It is one of the few species that can survive in heavy metal contaminated areas.It is of great significance for maintaining biodiversity and protecting the environment.Based on a review of domestic and foreign research literature,the protection status of the Empetrum nigrum in the Greater Xing'an Mountains of Heilongjiang was investigated and analyzed,and the characteristics of the Empetrum nigrum in the region were analyzed,and the protection countermeasures were proposed.
