摘要
以黄河东部宁夏吴灵灌区为研究区域,基于模糊综合评判进行地下水水质评价,借助sufer软件,选取10个有代表性的水质指标进行评价。利用sufer软件生成吴灵灌区矢量网格地图,由最近邻点插值法确定研究区域内各个网格的水质分类,并绘制吴灵灌区地下水水质类别图。结果表明:区域大范围分布有Ⅰ类水、Ⅱ类水、Ⅲ类水,在西南和东北部的农业、生活密集地区则分布有较大范围的Ⅳ类水,Ⅴ类水在研究区基本不可见。
Based on fuzzy synthesis, this paper selected 10 representative water quality indicators for the evaluation in the study area of Wuling irri- gation area in Ningxia Hui Autonomous Region in the east of the Yellow River, with the aid of the sufer software. The vector grid map of Wuling ir- rigation area was generated with the sufer software. Through the Nearest Neighbor Interpolation Method to determine the water quality classification of each grid in the study area, the groundwater quality class diagram of Wuling irrigation area was drawn. The results show that class Ⅰ , Ⅱ and Ⅲ water is distributed in large range of the study area; the distribution range of class Ⅳwater is large in the southwest and northeast agricultural con- centrated area and class V water in the research area is basic invisible.
