摘要
以灰色理论为基础,提出了赋权共原点灰色聚类方法,并将该方法应用于10个大型水库的富营养化程度评价中,结果表明该方法具有监测数据利用率高、评价结果可靠、实用性强等特点,是一种评价水库富营养化程度的有效方法。
Based on grey theory,gray clustering model uses the clustering function with co-origin and sub-section.This method uses subsection and co-origin to calculate the clustering function and uses the optimized analytic hierarchy process to carry on the reasonable empowerment to establish the evaluation model of reservoir eutrophication.This model is applied to the evaluation of eutrophication level of 10 large reservoirs.Compared with other methods,this method has high efficiency of evaluation monitoring data,and its results are reliable and practical.
