摘要
为了探讨在湖泊的富营养化评价中不同评价方法和不同因子的关系,应用灰色局势决策法及模糊综合法对我国巢湖的富营养化程度进行了评价,并对评价结果的贴近率进行了分析。通过对实例的分析,得出灰色局势决策评价法评价结果的贴近率随因子组合权重的递增而上升,且在因子个数相同(因子个数大于1)的条件下,灰色局势法评价结果的贴近率大于模糊综合法。
In order to analyze the relationship of different assessment methods and different factors,in this article Grey system policy and Fuzzy transformation were applied to evaluate the degree of eutrophication of Chao lake.And analyse the assessment close rate result was analyzed.By the analysis of the example,the assessment result of close rate of Grey Sitiation Decision Method can rise with weight of composing factor rising.And in the condition of factor quantity being identical（factor quantity〉1）,the assessment result of close rate of Grey Sitiation Decision Method exceeded the Fuzzy Method.
