【摘要】 依据河南省宿鸭湖水库2006年-2011年水质监测数据,采用指数法对水库进行地表水环境质量评价和水库富营养化评价,并采用相应的模型核算水环境容量,结果表明,2011年,该水库水质满足地表水水域环境功能,水库富营养化程度为中度富营养化,2006年-2011年评价时段内水质变化总体上稳定,略呈加重趋势。通过采取有效的污染控制措施及针对性的对策,可降低湖水中污染物水平,确保该水库留有环境容量(COD 5 587.46 t/a,氨氮451.47 t/a),保障水库综合效益的发挥,进一步促进当地经济、社会和环境的可持续发展。更多还原

【Abstract】 Based on the practical monitoring data of Suyahu Lake Reservoir in 2006-2011,this study assessed the ground water quality and eutrophication by adopting the methods of indices and water environment capacity.The results show that water quality of the reservoir meets related standards,and eutrophication level of the reservoir belongs to moderate eutrophication in 2011.The water quality in 2006-2011 is stable on the whole,on a slightly increasing pollution trend.Some measures were taken to reduce the contamination by means of pollution control and some pertinent countermeasures to ensure the integrative benefits and adequate capacity(COD 5587.46t/a,Ammonia nitrogen 451.47t/a)in a bid to boost sustainable development of economy,society and environment in Zhumadian City.更多还原
