摘　　要：为了客观、准确评价受黄土高原土壤影响的水源地的水质类别,选取蒲河巴家嘴水库型水源地作为典型,应用物元可拓理论建立物元模型和关联函数,选定高锰酸盐指数等评价因子,用实测的2005—2014年水质数据分析计算其综合关联度和可拓指数,评价了该水源地的水质类别。评价中考虑了水体主要水化学指标高锰酸盐指数和氨氮含量较低,而总硬度与硫酸盐含量较高的特点。与单指标评价法和综合评价法相比,物元可拓法评价受黄土高原土壤影响下的水源地水质状况比较科学,符合实际情况。In order to make an objective and accurate evaluation on water quality classification of the Loess Plateau soil influenced water source,Gansu Bajiazui Reservoir water source was studied by matter element analysis method. In this paper,water quality data during the period of 2005-2014 were analyzed to evaluate the water quality classification by Permanganate Index. The results comprehensively considered the actual situation of the lower permanganate and ammonia nitrogen and higher total hardness and sulfate content. Compared with single-factor evaluation method and comprehensive evaluation method,the matter element analysis method made the water quality evaluation results of water source more scientific and reasonable.
