摘要
运用样线法、样方法等在武汉市藏龙岛国家湿地公园开展植物多样性科学调查。公园内共有维管束植物222种,隶属于85科182属。其中,蕨类植物6科,7属,11种;裸子植物4科,8属,10种;双子叶植物62科,127属,160种;单子叶植物13科,40属,41种。分析了湿地公园的主要植被分类情况和植物区系构成及分布,园内主要有针叶林、阔叶林及草丛三类植被,其中含10属以上的科有禾本科、菊科和蔷薇科,科的分布以世界广布类型和热带广布类型为主,含5~9种及以上的大型属未发现有分布,属的分布以泛热带分布类型为主;调查了园内珍稀濒危保护植物和外来入侵植物的组成情况,计算了近8年来园区内植物科、属的变化情况,其中双子叶植物的数量变化最大,减少了14种67属96种。调查结果显示藏龙岛植物种类单一且植物多样性有整体下降趋势。并根据调查数据结果提出了针对性的保护措施,可为保护与科学管理藏龙岛公园提供参考。
A scientific investigation on plant diversity was carried out in Canglong Island National Wetland Park in Wuhan City by using sample line method and sample method.The results showed that there were 222 species of vascular plants belonging to 182 genera and 85 families.Among them,ferns contain 6 families,7 genera,11 species;gymnosperms 4 families,8 genera,10 species;dicotyledonous comprise plants 62 families,127 genera,160 species while monocotyledonous plants get 13 families,40 genera,41 species.This study analyzed the main vegetation classification and flora composition and distribution of wetland parks.There were three types of vegetation in the park:coniferous forest,broad-leaved forest and grassland.Among them,the families with more than 10 genera included Gramineae,Compositae and Rosaceae.The distribution of families was mainly world-wide type and tropical wide type,and the distribution of large genera with 5-9 species and above was not found.The distribution of genera was mainly pan-tropical distribution type.The composition of rare and endangered plants and invasive plants in the park was investigated,and the changes of plant families and genera in the park in the past 8 years were calculated.Among them,the number of dicotyledonous plants changed the most,reducing 14 species,67 genera and 96 species.The plant species in Canglong Island were single and the plant diversity and had an overall downward trend.Based on the results of the survey data,we put forward targeted protection measures,which provides a reference for the protection and scientific management of Canglong Island National Wetland Park.
