摘要
为分析水富港改建对金沙江水富段水生生态系统的影响,2010年12月-2011年6月对金沙江水富段的3个监测点进行了水生生物及水质的调查研究。共采集到浮游植物7门26科47属127种。其中硅藻有73种,占浮游植物总种类数的57.48%;浮游动物3门15科19属31种,其中原生动物种类最多,为15种,占浮游动物种类总数的48.39%;着生藻类有4门12科16属43种,其中硅藻34种,占着生藻类总种数的79.07%,为优势种群;底栖动物3门8种,其中环节动物最多,为3种。水质监测结果表明:金沙江水富段水质符合GB3838-2002规定的Ⅲ类水质要求。
Water aquality and community structure of aquatic organisms in chin -sha River were evaluated from December 2010 to June 2011.A total of 127 species of phytoplankton belonging to 7 phylum, 26 family and 47 genus were collect-ed.The bacillariophyta exhibited the highest species diversity , with 73 species （57.48% of the total）.And 31 species of zooplankton belonging to 3 phylum, 15 family and 19 genus were found.The protozoa exhibited the highest species diversi-ty, with 15 species （48.39%of the total.）.43 species of periphytic algae were caught , belonging to 4 phylum, 12 family and 16 genus., and the bacillariophyta exhibited the highest species diversity , with 34 species （79.07% of the total）.8 species of zoobenthos were collected , and the annelids exhibited the highest species diversity , with 3 species.By the anal-ysis, the water quality of ShuiFu section in Chin -sha River was Ⅲ-level.
