| 摘 要： | 根据2008年9月从昆承湖布设的12个监测点采集的样本中水质指标(叶绿素a、总磷、总氮和高锰酸盐指数)的浓度值,采用了灰色聚类法及模糊综合评价法对样本水质进行富营养化评价.灰色聚类法先建立白化权函数并无量纲化灰类来消除各水质指标浓度值量级差异的影响,然后根据水质指标浓度阈值的大小赋以其权值,综合水质指标对各级富营养状态...

| Abstract: | According to consistency value of water quality indicators such as Chl-a,TP,TN and CODMn of the samples taken from 12 monitoring sites located in Kuncheng Lake in September,2008,grey clustering method and fuzzy comprehensive assessment method were used to assess its eutrophication level.The grey clustering assessment method established the whitening function and did non-dimensional treatment to avoid the influence of magnitude of concentration values firstly,and then evaluated weights based on threshold of ... |
