摘　　要：自然保护区在维持和恢复珍稀濒危物种的生存力、保护自然生态系统与生物多样性等方面发挥着重要作用。明晰遵义市自然保护区保护现状及其保护效益,进而分析遵义市保护区的保护优先序列,对保护区内实施科学合理的保护与管理具有重要的意义。依据全省已建立的自然保护区信息评价分析所筛选出的保护优先区的保护现状,利用Dobson筛选法识别自然保护区重点保护物种及其分布格局。结果表明:(1)在珍稀濒危物种丰富度分布上,遵义市自然保护区物种保护呈现西北—东南密、西南—东北疏的特征;(2)采用“累积筛选”法共鉴别出对遵义市保护贡献率较高的前6个保护区,其保护贡献率累计达90%;(3)遵义市珍稀濒危动植物基本都受到了较为全面的就地保护,但仍存在保护空缺,这些保护空缺的识别可为遵义市自然保护区的发展规划工作提供一些参考。A nature reserve can preserve and restore the survival capacity of rare and endangered species in the biodiversity of natural ecosystems.This study aims to identify the priority conservation areas and richness of rare and endangered species in nature reserves of Zunyi City GuiZhou Province,China.The current status and conservation benefits of nature reserves were also evaluated to determine the prioritization of conservation efforts within these reserves.Dobson screening method was employed to identify the key protected species and their distribution patterns in the nature reserves.The results revealed that:(1)The richness and distribution of rare and endangered species exhibited a distinct pattern in the nature reserves,with a dense concentration from the northwest to the southeast,and a sparse distribution from the southwest to the northeast.(2)The"cumulative screening"method was implemented to identify the top six reserves with the highest contribution rates,where were accounting for 90%of the total contribution rate.(3)Since most of the rare and endangered flora and fauna were comprehensively protected in their natural habitats,there are still some areas to be improved.The identification of protection gaps can serve as the valuable guidance for the development and planning of nature reserves.
