摘要
对固城湖水环境现状进行了调查与评价。结果表明,除湖心区断面枯水期总磷达Ⅳ类标准外,其余断面平、丰、枯水期水质均达Ⅲ类水标准。固城湖水体呈中营养化状态,且综合营养状态指数已接近富营养状态。指出,面源污染,内源污染,养殖污染,流域内的航运污染是造成固城湖水体富营养化的主要原素。提出,应严格控制各类污染源,建立流域内的污水处理厂,保护森林植被,推广使用无磷洗涤剂、生态化肥、生态农药;定期疏浚湖底淤泥,改良现有水生植被结构;加大对固城湖环境、功能和开发利用的研究及湖泊富营养化的研究,对水体中的磷、氮的化学行为及平衡进行分析,预测发展趋势,制定营养物质种类,防止其湖水向藻型湖泊发展。
Water environment survey and evaluation of Gucheng Lake were made. Except in central lake, the TP can reach Ⅳ class standard, others can all reach Ⅲ standard. The water was under middle eutrophication state, and the comprehensive eutrophication index was close to eutrophication state. The facts which cause the eutrophication was discussed and the treatment approach was suggested.
