基于层次聚类和水质指数法的南水北调中线总干渠典型年份水质变化特征分析OA北大核心CSTPCD
Characteristics of water quality change in the canal of middle route project of South-to-North Water Diversion in typical years based on hierarchical clustering and water quality index method
为探明南水北调中线总干渠水质变化特征和时空分异规律,选择总干渠典型年份30个断面10个水质指标的逐月监测数据,利用层次聚类和WQI水质指数法对水质变化进行分析.层次聚类将总干渠划分为3个渠段,陶岔至柳家佐连续24个断面为第一渠段,该渠段各项水质指标浓度相对较低,其中F.coli((44.41±56.11)个·L-1)、CODMn((1.94±0.11)mg·L-1)、SO42-((29.38±1.68)mg·L-1)和 DO((9.74±1.42…查看全部>>
In order to investigate the characteristics and spatiotemporal differentiation of water quality in the middle route of the South-to-North Water Diversion project.The monthly monitoring data of 10 water quality indexes in 30 sections of the main canal in typical years were selected,and the variation of water quality was analyzed by hierarchical clustering and WQI water quality index method.The main canal was divided into 3 types of water quality canal segment…查看全部>>
