| 中文摘要: |
| ２００９年７月９－２３日（丰水期）和１１月１１－２５日（枯水期）在龙滩水库进行浮游植物采样调查，研究其浮游植物种类组成、数量变化特征、空间分布及群落多样性，评价了龙滩水库的水质现状，探讨水电开发对河流浮游植物的影响。结果表明，龙滩水库共检出浮游植物６门、３５属、５９种；其中，硅藻门２８种，绿藻门１７种，蓝藻门８种，甲藻门、红藻门、金藻门各２种。优势种为４门、１３种，包括颗粒直链藻（Melosira granulata）、钝脆杆藻（Fragi lariacapucina）、双头针杆藻（Synedra amphicephal）和双射盘星藻（Pediastrum biradiatum）等。龙滩水库浮游植物密度和生物量均值分别为３３．４×１０４个／Ｌ和２．５８０ｍｇ／Ｌ。多样性指数和均匀度指数分别为２．５８和０．９４。依据藻类生物学指标评价标准，龙滩水库水质为贫－中营养型。 |
| 英文摘要: |
| Species composition，density and biomass，spatial distribution and biodiversity of phytoplankton in Long-tan Reservoir were investigated during the period from July 9th to 23th (rainy season ) and Nov. 11thto 25 th(dry sea-son) 2009. Based on the results，we evaluated the situation of water quality of Longtan reservoir and investigated the impacts of hydropower development on the phytoplankton. The total of 59 species belonging to 35 genera for phytoplankton was recorded in the rainy and dry seasons. Of which，28 species in Bacillariophyta，17 species in Chlorophyta，8 species in Cyanophyta，2 species respectively in Pyrrophyta，Chrysophyta and Rhodophyta. The dominant species of phytoplankton were composed of 13 species to 4 genera，such as Melosira granulate，Fragilaria capucina，Synedra amphicephal, Pediastrum biradiatum，etc. The density and biomass of phytoplankton were 33.4x 104 ind. /L and 2580 mg/L, respectively. The Shannon-Wiener indexes and Pielou indexes were 2. 58 and 0. 94，respectively. According to the evaluation standards of algal biology indexes，the water quality of Logntan Reservoir belongs to mesotrophic-oligotrophic type. |
