摘　　要：2018年7月至9月期间,在海南岛北部的东寨港、五源河、美舍河、响水河、潭丰洋、三十六曲溪、铁炉溪和南丽湖湿地中,开展了3次植物调查和土壤样品采集工作,研究植物群落的物种组成、群落结构和物种多样性,分析了植物群落多样性与土壤因素的关系。研究结果表明,在海南岛北部8处湿地中,共记录107科330属434种植物,其中被子植物的物种数量为416种,其占总物种数量的95.85%;蕨类植物的物种数量为18种,其占总物种数量的4.15%;在8处湿地中,美舍河湿地中植物群落的物种多样性水平相对最高,其植物群落结构相对最稳定;8处湿地的土壤容重、p H、全氮含量、全磷含量、含水量、有机质含量、含盐量都对植物群落的物种多样性有直接影响。From July to September 2018,the plant investigation for 3 times were carried out,and the study was made on the species composition,community structure,and biodiversity of plant communities in 8 wetlands located in north Hainan Island,which were Dongzhai Harbor,Wuyuan River,Meishe River,Xiangshui River,Tanfengyang,Sanshiliuqu Strem,Tielu Stream,and Nanli Lake wetlands.The relationships between these plant communities and soil factors were analyzed.The results indicated that a total of 107 families,330 genera and 434 plant species were recorded in 8 wetlands in north Hainan Island;the number of angiosperm species(416 species)accounted for 95.85%of the total number of species,while the number of fern species(18 species)accounted for only 4.15%of the total number of species.Among 8 wetlands,the plant species diversity of Meishe River wetlands was the highest level and the structure of plant communities was the most stable.The soil bulk density,pH,total nitrogen content,total phosphorus content,water content,organic matter content,and salt content in 8 wetlands all directly influenced on the species diversity of the plant communities.
