中国是裸子植物多样性中心之一。近五分之一（195种）的裸子植物分布在中国，但69种受到威胁。目前，我国裸子植物特别是濒危裸子植物的保护状况仍不清楚，严重制约了裸子植物的全面保护。了解物种丰富度的分布格局，探讨物种丰富度与环境因子的关系是保护的关键。在这项研究中，我们首先建立了一个数据库的69种裸子植物受威胁的13 270分布记录。结果表明，其中31个网格单元（50 × 50 km）覆盖了我国所有受威胁裸子植物，受威胁裸子植物网格单元主要分布在黄河以南地区，分布中心在川西高原。对受威胁裸子植物的保护现状进行了评价，结果表明，有9种（13%）受威胁裸子植物分布在保护区外。因此，我国裸子植物濒危物种的保护工作仍存在空白。对无保护的濒危裸子植物应给予更多关注，对无详细分布记录的物种应进行分类学研究。最后提出了中国裸子植物受威胁优先保护区和优先保护级别。川西高原是裸子植物受威胁最重要的优先保护区。本研究对我国植物保护和森林经营具有一定的指导意义。
China is one of the diversity centers of gymnosperms. Nearly one-fifth (195 species) of gymnosperms are located in China, but 69 species are threatened. To date, the conservation status of gymnosperms, especially threatened gymnosperms in China, remains largely unknown, which seriously restricts the comprehensive protection of gymnosperms. Understanding the distribution pattern of species richness and exploring the relationships between species richness and environmental factors are key steps for their protection. In this study, we first constructed a database for the 69 threatened species of gymnosperms with 13 270 distribution records. It is found that 31 of the grid cells (50 × 50 km) cover all threatened gymnosperm species in China, and the grid cells of threatened gymnosperms are mainly distributed in the southern area of the Yellow River, with a distribution center in the Western Sichuan Plateau. Then, we evaluated the conservation status of threatened gymnosperms, and the results indicate that 9 (13%) threatened gymnosperms are distributed outside of nature reserves. Therefore, there are still conservation gaps in the protection of threatened gymnosperms in China. We should give more attention to unprotected threatened gymnosperms and conduct taxonomic studies on the species without detailed distribution records. Finally, conservation priority areas and priority conservation levels of threatened gymnosperms in China were proposed. The Western Sichuan Plateau is the most important conservation priority area of threatened gymnosperms. This study will shed light on plant protection and forest management in China.
