勐板河水库富营养化趋势分析及防治措施

Trend Analysis and Control Measures of Eutrophication in Mengbanhe Reservoir

利用综合营养状态指数法对勐板河水库2014-2018年水质进行营养状态分析,通过数据处理和分析得出,目前勐板河水库水质处于中营养状态,综合营养状态指数年均值有逐年上升的趋势,中营养状态的月份占比逐年增多。为有效防止水库水质进一步恶化,结合水库周边环境,初步分析了污染来源,并提出了防治措施及对策。

The water quality of Mengbanhe reservoir in 2014 to 2018 was analyzed using the method of comprehen-sive nutritional state index,and the result showed that the water quality of Mengbanhe reservoir was in medium nu-tritional state at present,the annual mean value of Comprehensive Nutritional Status Index showed an upward trend,and the proportion of nutritional status in months increased year by year.In order to effectively prevent the further deterioration of the water quality,combined with the reservoir surrounding environment,the pollution sources were preliminarily identified,and the prevention measures and countermeasures were put forward.
