摘要
采用单因子指数法、综合水质标识指数法对山东济南白云湖湿地公园、山东钢城大汶河湿地公园两个不同类型的湿地公园进行地表水环境质量分析与评价。结果表明:8处监测点位的单因子水质标识指数均达到Ⅱ或Ⅲ类水质标准,8处监测点位的综合水质标识指数介于2.7~4.01之间,综合水质级别为Ⅱ-Ⅲ类水平,湖泊型出水口处的综合水质标识指数最大,湖泊型入口次之,高锰酸盐指数、总磷是存在的主要水环境问题。不同类型湿地公园水质存在差异,整体呈现出河流型湿地公园优于湖泊型湿地公园,其中湖泊型湿地公园存在Ⅲ类水平的点位相对较多。同一湿地公园不同位置水质存在差异,对于湖泊型湿地公园,综合水质标识指数呈现出湖中优于周边;对于河流型湿地公园,多数下游水质优于上中游水质。
The surface water environment quality of two different types of wetland parks,Baiyun Lake Wetland Park in Jinan,and Dawen River Wetland Park in Gangcheng,was analyzed and evaluated by using the single-factor index method and the composite water quality marking index method.The results show that the single-factor water quality labeling indexes of the eight monitoring sites reached the water quality standard of Class II or III,the integrated water quality labeling indexes of the eight monitoring sites ranged from 2.7 to 4.01,and the integrated water quality level was at the level of Class II-III.The integrated water quality labeling indexes at the lake-type outlet were the largest,and the lake-type inlet was the second largest,and the permanganate index and the total phosphorus were the main water environment problems.There are differences in the water quality of different types of wetland parks,and the overall situation shows that river-type wetland parks are better than lake-type wetland parks,in which there are relatively more points with Class III level in lake-type wetland parks.There are differences in water quality in different locations of the same wetland park,for lake-type wetland parks,the comprehensive water quality labeling index shows that the middle of the lake is better than the surrounding area;for river-type wetland parks,most of the water quality in the downstream is better than the water quality in the upper and middle reaches.
