The three most north-eastern provinces of China (Heilongjiang, Jilin, and Liaoning) are rich in natural resources and have favourable geographical conditions, making them home to a large number of wild plant species. This paper summarises the distribution characteristics, endangerment degree and research status of nationally protected plants in these provinces based on online databases, literature review and field surveys.
The results show that the north-eastern provinces have 31 families, 38 genera and 51 species of nationally protected plants. The endangered status includes both the endangered assessments made by China and those made globally. China has assessed 38 plant species as endangered, while 19 plant species are assessed as endangered globally. Currently, most of the protected plants have been studied, with in-situ and ex-situ conservation being the primary protective measures. In addition, this study also identified seven species of plants that are basically not covered by research and lack sufficient studies in the current literature and urgently need further in-depth investigation and long-term monitoring in order to improve the relevant conservation measures. This study provides a scientific basis for the conservation vacancies of plants under national key protection in the three north-eastern provinces, as well as a reference for formulating effective conservation policies and promoting further research.
中国东北三省（黑龙江、吉林和辽宁）自然资源丰富，地理条件优越，拥有大量野生植物物种。本文基于在线数据库、文献综述和实地调查，总结了这些省份国家重点保护植物的分布特征、濒危程度和研究现状。
结果表明，东北三省有国家重点保护植物31科、38属、51种。濒危状况包括中国和全球的濒危评估。中国已将38种植物评估为濒危，而全球有19种植物被评估为濒危。目前，大多数保护植物已被研究，就地保护和迁地保护是主要保护措施。此外，本研究还确定了7种植物在当前文献中基本未被研究且缺乏充分研究，迫切需要进一步深入调查和长期监测，以完善相关保护措施。本研究为东北三省国家重点保护植物的保护空缺提供了科学依据，也为制定有效的保护政策和推动进一步研究提供了参考。
