| 开展已有就地保护体系对生物多样性的保护现状评估有利于科学指导下一步保护规划工作。本研究收集华北地区46个国家级自然保护区的科学考察报告、多样性研究报告及其他相关文献资料，整理构建了华北地区药用维管植物保护名录数据库，并利用此数据库分析了该地区药用维管植物的就地保护状况。结果发现：华北地区国家级自然保护区不同程度保护了2 364种药用维管植物，隶属于165科800属；其中，1 710个物种（占总数的72.34%）受保护程度一般，分布的保护区数量少于10个，仅62个物种（占总数的2.62%）受到有效保护，分布的保护区数量大于30个；不同保护类型的保护区对药用维管植物所发挥的保护作用不同，森林生态类型保护区发挥的保护作用最大，保护了华北地区89.04%（2 105/2 364种）的药用维管植物。研究认为华北地区国家级自然保护区对该地区药用维管植物的就地保护发挥了重要作用，但现有保护状况可进一步完善，尤其应该重视森林生态类型保护区的建设工作以及珍稀濒危药用植物的保护规划。 |

| Abstract: |
| Evaluation of the conservation effectiveness of the current in situ conservation network on biodiversity can help to provide scientific basis for the conservation planning of biodiversity. In this study， we collect the species list occurred in 46 national nature reserves in North China from the scientific investigation reports， biodiversity researches and other related literatures of the national nature reserves， and evaluate the in situ conservation status of wild medicinal vascular plants in this region. The results showed that a total of 2 364 medicinal vascular plants， belonging to 800 genera and 165 families， are preserved by 46 national nature reserves in North China. 72.34% （1 710/2 364） of all medicinal vascular plants species are preserved within less than 10 national nature reserves， indicating low in situ protection degree for these species. Only 2.62% （62/2 364） of all medicinal vascular plants species are preserved within more than 30 national nature reserves， indicating sufficient in situ protection degree for these species. In addition， we found that different protection types of national nature reserves differed in their protection effectiveness in medicninal vascular plants. The nature reserves with protection type of forest ecosystem had the best protection effectiveness， preserving 89.04% （2 105/2 364） of all medicinal vascular plants species across the whole region. The national nature reserves has played an important role in the in situ conservation of medicinal vascular plants in North China. However， we still suggest that more efforts could be made to improve the conservation effectiveness of the current national nature reserves network for medicinal vascular plants in this region， and special attentions could be paid to the construction of nature reserves with protection type of forest ecosystem and to the conservation plans of rare and endangered medicinal plants. |
