摘要
梁子湖水质年际间波动较大,区域差异明显;按多年均值评价,武汉江夏水域南北嘴点水质为Ⅲ类,鄂州水域梁子岛点为Ⅳ类;按综合营养状态指数法评价,全湖营养水平为中营养。指出梁子湖主要水环境问题为氮磷污染。在分析氮磷污染来源的基础上,提出了在治理工业废水、城镇生活污水、规模化畜禽养殖污染和农业面源污染的同时防治水产养殖和旅游污染综合防治对策。
Water quality of Liangzi Lake is changeable in years and areas, with water quality at Jiangxia area, Wuhan up to Class III, at Ezhou area up to Class IV. The Lake is in the state of medium eutrophication according to comprehensive nutrition index assessment, with nitrogen and phosphorus as major pollutants.
