2008年6月对蕉岭石窟河国家级水产种质资源保护区的浮游植物群落组成及水环境状况进行初步调查,结果发现浮游植物(包括变种、变型)5门30属63种。其中,绿藻18属43种,占总种数的68.25%;硅藻5属10种,占总种数的15.87%;蓝藻4属6种;甲藻2属3种;隐藻1种。绝对优势种为扎卡四棘藻(Attheya zachariasi),隐藻(Cryptomonas sp.)、细小隐球藻(Aphanocapsa elachista)和双对栅藻(Scenedesmus bijuga)的优势程度次之。从浮游植物种类组成和多样性指数水平来看,该保护区的水体存在一定程度的富营养化,属中度污染。
In June 2008, a preliminary investigation of phytoplankton community composition and water environment in Jiaoling Grottoes National Aquatic Germplasm Resources Conservation Area revealed that there are 63 species of phytoplankton (including varieties and variants) in 5 genera and 30 genera. Among them, there are 43 species of 18 genera of green algae, accounting for 68.25% of the total species; 10 species of 5 genera of diatoms, accounting for 15.87% of the total species; 6 genera of 4 genera of cyanobacteria; 3 species of 2 genera of dinoflagellates; The dominant species were Attheya zachariasi, Cryptomonas sp., Aphanocapsa elachista and Scenedesmus bijuga. According to the species composition and diversity index of phytoplankton, the water body of this reserve has some eutrophication and is moderately polluted.
