| 掌握保护区珍稀植物本底与受威胁状态，完善保护区珍稀植物的优先保护评价体系，可为保护区制定保护对策、科学管理提供依据。通过资料收集和实地考察，对连州田心省级自然保护区珍稀植物资源开展研究，结果表明，田心省级自然保护区共有珍稀植物35科63属94种，其中国家重点保护野生植物有25科33属46种，广东省重点保护野生植物有7科10属10种，中国植物红皮书稀有濒危植物20科25属25种，CITES公约附录植物5科23属46种。采用优先保护评价体系对41种代表性珍稀濒危植物进行排序，结果属Ⅰ级保护的有2种，占评价总数的4.88%；属Ⅱ级保护的有22种，占评价总数的53.66%；属Ⅲ级保护的有17种，占评价总数的41.46%。田心省级自然保护区生境良好，珍稀濒危植物种类多，数量丰富，具有较高的生态保护价值。该评价体系对41种植物的评价与分级结果更真实地反映了它们在田心保护区受威胁状态和优先保护顺序，对该区珍稀濒危植物的优先保护工作具有一定指导意义。 |

| Abstract: |
| Mastering the basic situation and threatened status of rare and endangered plants， improving the priority protection evaluation system for rare plants in protected areas， can provide a basis for formulating protection strategies and scientific management in protected areas. Field investigation and data colleation were used to study the rare and endangered plant resources in Tianxin Provincial Nature Reserve. The findings reveal that Tianxin Provincial Nature Reserve of Guangdong has a total of 35 families， 63 genera， and 94 species of rare and endangered species， of which 25 families， 33 genera， and 46 species are national key protected wild plants； 7 families， 10 genera， and 10 species are key protected wild plants of Guangdong Province； 20 families， 25 genera， and 25 species are rare and endangered plants in China Plant Red Data Book. There are 5 families， 23 genera， and 46 species of plants listed in CITES. 41 species of rare and endangered plants were ranked by the priority protection evaluation system. The results show that 2 species belong to level Ⅰ protection， accounting for 4.88%； 22 species belong to level Ⅱ protection， accounting for 53.66%；17species belong to level Ⅲ protection， accounting for 41.46%. The excellent habitats and abundant rare and endangered plants indicate a great conservation value in the nature reserve. The evaluation and classification results of 41 species of plants in this evaluation system more truly reflect their threatened status and priority protection order in the Tianxin Provincial Nature Reserve， which has certain guiding significance for the priority protection of rare and endangered plants in this area. |
