Abstract: Based on field investigation, the paper preliminarily discussed the floristic characteristics, geographical distribution, ecological environment, relationships with adjacent regions and species endangerment assessment of lycophytes and ferns in Jingning She Autonomous County. 296 species, seven varieties and one hybrid species belonging to 83 genera and 29 families were discovered, including nine new distribution records in Zhejiang Province. The geographical elements of lycophytes and ferns were mainly of tropical nature as to the genera, and the species were mainly of temperate nature. This area belonged to the convergence zone of subtropical and temperate species. Compared with the adjacent provinces and regions, the locophyte and fern flora of Jingning were most similar to those in Jiangxi Province, Fujian Province, Ningbo City and Wenzhou City. They were more close to the flora of Wenzhou and less with Anhui. The ecological types of lycophytes and ferns in Jingning could be roughly divided into six categories: warm coniferous forest habitat, broad-leaved evergreen-forest shady and wet habitat, bamboo thicket warm and wet habitat, temperate pine, fir and cypress cold and wet habitat, drought habitats near shrubs and village roadsides, wetland habitats in streams, farmlands and marshes. Among them, the broad-leaved evergreen-forest shady and wet habitat had the highest diversity of species. There were 46 threatened lycophytes and ferns in Jingning, Zhejiang Province, including 11 endangered species (EN), 35 vulnerable species (VU) and four of them were provincial protected species.

摘要： 在野外调查的基础上，初步探讨了景宁畲族自治县石松类和蕨类植物的区系特征、地理分布、生态环境以及与邻近地区的关系和物种濒危状况。结果表明，景宁石松类和蕨类共有296种7变种和1杂交种，隶属于29科83属，其中包括7个浙江省新记录种；地理分布以热带性质的科属占优势，种类以温带性质为主，本区属于亚热带与温带物种的融汇地带；与邻近省份和地区相比，景宁石松类和蕨类区系与江西省、福建省、宁波市和温州市的关系密切，与温州的区系最紧密，与安徽的区系较疏远；景宁石松类和蕨类生态类型大致可分为六类：暖性针叶林生境、常绿阔叶林阴湿生境、毛竹林暖湿生境、温性松杉柏冷湿生境、灌丛及村旁路边干旱生境和溪流、农田、沼泽湿地生境，其中常绿阔叶林阴湿生境下物种最丰富；景宁分布着在浙江范围内受威胁的蕨类46种，其中濒危(EN)有11种，易危(VU)有35种，国家和浙江省保护蕨类4种。
