中文摘要: |
吉木乃红山水库是天然水源型水库,通过对水库平水期(7月)、枯水期(10月)和丰水期(5月)浮游植物群落的调查分析,共鉴定出浮游植物8门、109种(属);其中优势种为小球藻(Chlorellavulgaris)、拟菱形弓形藻(Schroederianitzschioides)、双对栅藻(Scenedesmusbijuga)、四尾栅藻(Scenedesmusquadricauda)、长锥形锥囊藻(Di nobryonbavarium)、拟气球藻(Botrydiopsisarhiza)、广源小环藻
(Cyclotellabodanica)和短线脆杆藻(Fragilariabre
vistriata)。经多样性指数分析,红山水库水体隶属中度富营养化水体,浮游植物群落结构属于绿藻-硅藻型,不同时期浮游植物生物密度趋势为:平水期(3.73±0.38)×106个/L>枯水期(2.46±0.20)×106 个/L>丰水期(1.19±
0.22)×106个/L。库区水体中浮游植物的种类组成、密度、多样性指数等呈典型的季节相关性。 |
英文摘要: |
Hongshan reservoir which is open water supplied and located in Jimunai is one of the many reservoirs inXinjiang. Phytoplankton community structure of Hongshan reservoir was investigated and analyzed in July 2008,October 2008 and May 2009. A total of 109 phytoplankton species,belonging to 8 phylum were identified. Chlorella vulgaris,Schroederia nitzschioides,Scenedesmus bijuga,Scenedesmus quadricauda,Dinohryon bavarium,Botrydiopsis arhiza,Cyclotella hodanica as well as Fragilaria brevistriata are the dominant species. The phytoplankton community structure was typical Chlorella-diatoms type showed that the water body of Hongshan reservoir was moderate eutrophication. The biomass density was greatest in the normal water season,and the wet season has the smallest biomass density. And the phytoplankton composition,biomass density,and diversity was closely related to the weather of Hongshan reservoir was also discovered.
