山西省重点保护野生植物就地保护现状

建立自然保护区是生物多样性保护最为直接和有效的方法。开展重要保护物种的科学考察和研究, 评价其就地保护现状, 对区域内实施科学合理的保护与管理具有重要的意义。本文基于文献资料和野外调查, 分析了山西省重点保护野生植物的地理分布及就地保护现状, 结果显示: (1)山西省重点保护野生植物共57种, 其中有49种分布在自然保护区内, 就地保护率为86%; (2)在地理分布上, 晋城、运城、临汾和阳泉4个市的保护区内分布的保护植物种类最多; (3)采用“累计筛选法”共鉴别出6个保护贡献率最高的保护区, 其累计保护贡献率达到86%; (4)总体来说, 山西省重点保护野生植物受到较全面的就地保护, 但仍存在一些保护空缺, 这些保护空缺地的鉴别将为山西省自然保护区的进一步规划提供科学参考。

Assessing the in situ conservation status of key protected wild plants in Shanxi Province

Establishing nature reserves to protect species and their habitats, is the most direct and effective approach for biodiversity conservation. Conducting investigations of the important protected species and assessing their in situ conservation status are of important guiding significance for reasonable conservation and effective management within a region. In this paper, based on the literature and field investigations, we analyzed the distribution and protection status of the key protected wild plants in Shanxi Province. The results showed that there were 57 key protected wild plants in Shanxi, 49 of which were distributed in nature reserves, and the in situ conservation rate was 86%. The nature reserves in Jincheng, Yuncheng, Linfen, and Yangquan cities contained the most protected wild plant species. Cumulative screening was used to select the six nature reserves with the highest contributions. The cumulative protection contribution rate of these six reserves was 86%. In general, the key protected wild plants are under comprehensive protection in Shanxi. However, there are still some protection gaps, and these identified gap areas will provide a scientific basis for further planning and development of nature reserves in Shanxi Province.
