安徽省宿松县龙感湖和黄大湖枯水期水质现状分析

Analysis on the Current Situation of Water Quality of Longgan Lake and Huangda Lake during Low-water Period in Susong County of Anhui Province

[目的]研究枯水期龙感湖和黄大湖水质状况。[方法]通过在龙感湖、黄大湖及沿湖沟渠合理布设监测点,根据国家标准开展水质指标分析,通过枯水期水质状况,探讨可能的影响因素。[结果]宿松县龙感湖、黄大湖水体总氮浓度大部分区域达到Ⅲ类,总磷浓度基本达不到Ⅲ类,沿湖沟渠水质基本达不到Ⅲ类。畜禽养殖、渔业粗放式发展、农村生活源是总氮和总磷主要的污染来源,应结合自身污染程度和发展定位采取相应的污染控制策略。[结论]该研究为理清宿松水域污染现状、生态环境与渔业资源保护提供理论依据。

[Objective]The research aimed to study the water quality of Longgan Lake and Huangda Lake during low-water period.[Method]The monitoring points were reasonably arranged in Longgan Lake,Huangda Lake and along the lake ditch,the water quality indicators were analyzed according to national standards,and the possible influencing factors were discussed through the water quality during the dry season.[Result]The total nitrogen concentration in the water bodies of Longgan Lake and Huangda Lake in Susong County reached the third category,and the total phosphorus concentration was basically less than ClassⅢ.The water quality along the lake ditch was basically less than ClassⅢ.Livestock and poultry breeding,extensive development of fisheries,and rural living sources were the main sources of pollution of total nitrogen and total phosphorus.Corresponding pollution control strategies should be adopted in combination with their own pollution levels and development orientation.[Conclusion]The research provides a theoretical basis for rationalizing the pollution status,ecological environment and fishery resources protection in Susong waters.
