摘　　要：采用全面踏查、样带和样方相结合的方法,对分布于浙江景宁畲族自治县驮岙头林区珍稀蕨类植物福建观音座莲资源现状及其群落进行调查。结果表明,植被类型为人工杉木林,其中福建观音座莲分布面积为2.332 hm 2,共有135株,种群结构为:1~2年生38株,3~4年生52株,5年生以上45株;群落分三层,乔木层为杉木单优种群,灌木层以大叶白纸扇、杜茎山等为优势种,草本层以薄盖短肠蕨、福建观音座莲等为优势种,群落内共有维管植物123种,隶属于54科99属,植物区系属的地理分布热带成分占68.2%,温带成分占31.8%;群落类型为杉木——大叶白纸扇+杜茎山——薄盖短肠蕨+福建观音座莲群丛,目前处于乔木层相对稳定、灌木层快速生长、草本层剧烈竞争的演替阶段。建议设立自然保护小区进行动态监测,开展扩繁保育等研究,保持福建观音座莲种群的稳定和增长。The resource status and community of Angiopteris fokiensis,a rare fern distributed in Tuo'aotou forest area of Jingning She Autonomous County,Zhejiang Province,were investigated using the method of comprehensive investigation,transect and quadrate.The results showed that the vegetation type was artificial Chinese fir forest,in which Angiopteris fokiensis had a distribution area of 2.332 hm 2 and a total of 135 plants.The population structure was as follows:38 plants aged 1-2 years,52 plants aged 3-4 years,and 45 plants aged over 5 years.The community was stratified into three layers:the tree layer was dominated by Chinese fir,the shrub layer by species such as Mussaenda shikokianaand Maesa japonica,and the herb layer by species such as Allantodia cristata and Angiopteris fokienensis.A total of 123 vascular plant species belonging to 99 genera in 54 families were identified within the community.The geographical distribution of the flora at the genus level was predominantly tropical(68.2%)with temperate elements accounting for 31.8%.The community type was characterized as a Chinese fir-Mussaenda shikokiana+Maesa japonica-Allantodia cristata+Angiopteris fokienensis association,currently in a successional stage of relatively stable tree layer,rapidly growing shrub layer,and intense competition in the herb layer.It is recommended to establish a nature reserve for dynamic monitoring and conduct research on propagation and conservation to maintain the stability and growth of the Angiopteris fokienensis population.
