摘要
为了掌握陆浑水库的富营养化情况,采用熵值密切值法结合湖库富营养化评估标准,对其2009-2015年的营养状况进行评估。结果表明:该水库为轻度富营养化,主要表现为总氮超标;将该方法与线性插值评分法相比较,两者存在差异,线性插值法的主观性较大且没有考虑各指标对评估结果的影响,而熵值密切值法能够减少主观性,还能确定影响水质的主要因素,使富营养化状况的评估结果更符合实际。因此,熵值密切值法可以作为评估水体水质的常用方法。
To monitor the eutrophication of Luhun Reservoir,the entropy osculating value method combined with the eutrophication evaluation criteria of lake and reservoir was applied to evaluate the nutrient status of Luhun Reservoir from 2009 to 2015.The results showed that the reservoir was in slightly eutrophication with total nitrogen exceeded the standard.There were differences between the entropy osculation method and the linear interpolation scoring method.There was more subjective without considering the impact of various indicators on the evaluation results for the linear interpolation scoring method,whereas the entropy osculation value method could reduce this subjectivity and can determine the main factors affecting the water quality,which made the evaluation results more consistent.Therefore,the entropy osculation value method can be used as a common method to evaluate water quality.
