【摘要】：黄河是宁夏地区最重要的地表水资源,所以整个黄河宁夏段水环境质量的优劣将影响宁夏社会经济的发展。基于2010年-2014年宁夏环境监测站的统计资料,以污染最严重的指标COD、氨氮、总磷的监测资料为基础,采取物元分析法、模糊聚类法及WASP模型对黄河干流宁夏段水质监测断面的布设进行优化。结果表明:现有的6个国控监测断面对黄河干流水质变化状况的监测不完善,须增设2个监测断面,分别位于下河沿与金沙湾国控断面间及叶盛公路桥与银古公路桥国控断面间,地理位置分别处于石空镇与临河镇,即105°40′31″E,37°34′04″N与106°18′36″E,38°16′11″N。
[Abstract]:The Yellow River is the most important surface water resource in Ningxia, so the quality of water environment in Ningxia section of the Yellow River will affect the development of Ningxia's social economy. Based on the statistical data of Ningxia environmental monitoring station from 2010 to 2014, and based on the monitoring data of COD, ammonia nitrogen and total phosphorus, the matter element analysis method was adopted. Fuzzy clustering method and WASP model were used to optimize the layout of water quality monitoring section in Ningxia section of the Yellow River. The results show that the existing six state-controlled monitoring sections are not perfect for monitoring the water quality of the main Yellow River, and two monitoring sections should be added. It is located between the state-controlled cross sections of Xiahe River edge and Jinsha Bay and between the state-controlled sections of Yesheng Highway Bridge and Yingu Highway Bridge respectively. The geographical location is 105 掳4031 "E _ (37 掳34) ~ (4)" N and 106 掳18 ~ (36) "E ~ (38 掳1611") "N respectively.
