| 摘 要： | 研究利用GIS空间分析与地统计分析工具,采用模糊综合评价方进行地下水水质评价。以吉林省为研究区域,选取10项具有代表性的水质指标进行评价。利用GIS生成吉林省矢量网格地图,由克里格插值估算出研究区域内的评价指标值,得到以网格为单位的各单项指标的预测分布图。根据模糊综合评价模型,评价吉林省地下水水质状况,并绘制吉林省地下水水质类别图。结果表明:区域内Ⅲ类水分布最为广泛,其次为Ⅴ类水;东部、南部城市延边、白山、通化、辽源等水质状况良好,达到Ⅲ类以上,其中白山及延边部分地区地下水类别达到Ⅱ类;白城、松原、长春及吉林市的部分地区地下水环境质量状况较差,属于Ⅴ类水质,其原因在于氟化物与氨氮污染较重。

| Abstract: | Based on GIS spatial and geostatistical analysis,the groundwater quality of Jilin Province was assessed using the method of fuzzy comprehensive evaluation.Choosing Jilin Province as the case study area,10 typical indices were selected as evaluation targets.On the basis of vector-grid map of Jilin Province generated by GIS,the assessment prediction map of each index was obtained by using the method of Kigring interpolation.According to fuzzy comprehensive evaluation,the regional groundwater quality was grade... |
