摘要： 为了避免单点位湖泊水质分析的片面性，提高湖泊水质分析的准确性，明确湖泊水质空间分布的特征，对银川市鸣翠湖利用国标水质分析检测方法，开展多点位水质综合评价，同时利用GIS空间分析手段中的反距离权重法，开展污染物空间分布研究。结果显示，湖泊内部不同区域综合水质评价结果存在一定的差异，单点位水质分析的结果不足以反映湖泊整体水质状况，污染物空间分布显示对水质影响较大的BOD5、CODcr、氨氮、总氮空间分布变化明显。空间分布的结果可以为湖泊水质的综合治理指明方向。因此，天然湖泊水质分析应进一步开展多点位综合评价和污染物空间分布研究。

Abstract: In order to avoid single point analysis for water quality of lakes, improve the accuracy of lake water quality analysis, in order to identify the characteristics of the spatial distribution of water quality in lakes, carrying out multiple comprehensive assessment of water quality by standard water quality analysis detection method in Mingcui Lake, Yinchuan, and using GIS spatial analysis methods of inverse distance weighted method to study the spatial distribution pollutants. The results showed that: there were some differences in different areas of comprehensive evaluation of water quality of lakes internal results, analysis of the single point water quality results were not enough to reflect the overall water quality condition of lakes, and spatial distribution of pollutants displayed effect on water quality change of BOD5, CODcr, ammonia nitrogen, total nitrogen spatial distribution more difference, indicated the direction of comprehensive management of spatial distribution of the results for lake water quality. Therefore, water quality analysis of natural lakes should further develop multi-point comprehensive evaluation and spatial distribution of pollutants.
