海口美舍河国家湿地公园水质分析研究

Analysis and Research on Water Quality of Meishe River National Wetland Park in Haikou

为了揭示海口美舍河国家湿地公园的水环境现状和水资源动态变化,文章使用单因子指数法、综合指数法和模糊综合法对该区上游、中游与下游3个河段监测的水质数据进行分析,结果表明:(1)美舍河中、下游的pH、盐度、COD和NH3-H的数值均高于上游;(2)单因子指数法和综合指数法分析显示是上、中、下游3个监测点均为Ⅴ类水质;(3)模糊综合法分析表明上游的沙坡水库和中游的国兴桥监测点水质评价均为Ⅴ类水,下游的和平桥监测点为Ⅳ类水。

In order to reveal the current water environment and dynamic changes of water resources in Haikou Meishe River National Wetland Park,this research used single factor index,comprehensive index and fuzzy comprehensive methods to analyze water quality data of monitor points in the upstream,middle and downstream reaches of the river.The results shows:1)the pH,salinity,COD and NH3-H values in the middle and lower reaches of the Meishe River are higher than the upper reaches;2)the analysis of single factor index and comprehensive index method shows that the three monitoring points are all Grade V water quality;3)the fuzzy comprehensive method that the water quality evaluation of the Shapo Reservoir and the Guoxing Bridge monitoring points are both GradeⅤwater,and the Heping Bridge monitoring points is GradeⅣwater.
