摘要
为了解大渡河上游水域生态环境现状,该研究于2017-2018年春冬季2次对大渡河上游玛柯河至脚木足河段浮游植物进行收集分析,查明了浮游植物的动态变化和群落结构特征。结果显示,此次调查水域的浮游植物共鉴定出102种(属),隶属于6门46属。其中硅藻门占绝对优势,有76种(属),占浮游植物总物种数的74.5%。各河段春季的浮游植物平均密度和生物量比冬季都有显著的增加,分别增加了3.7和2.8倍,但总体呈现低密度和低生物量的特征。为获得该水域浮游植物本底资源现状及水生态监测提供了基础数据。
In order to understand the ecological environment status of the upper reaches of Dadu River,this study collected and investigated phytoplankton community structure and dynamic changes from Make River to Jiaomuzu River in the upper reaches of Dadu River twice in the spring and winter of 2017-2018.The results showed that a total of 102 species(genera)of phytoplankton were identified,belonging to 6 phyla and 46 genera.Among them,diatom is the absolute dominant,with 76 species(genera),accounting for 74.5%of the total phytoplankton species.The average density and biomass of phytoplankton in spring increased significantly compared with that in winter,increasing by 3.7 and 2.8 times,respectively,but the overall density and biomass were low.It provides basic data for obtaining the status of phytoplankton background resources and water ecological monitoring in this water area.
