| 摘 要： | 以关中盆地潜水为研究对象,分析了含水层脆弱性的影响因素,建立了含水层脆弱性评价指标体系及评价标准,结合GIS技术,用模糊迭代自组织数据分析技术(模糊ISODATA聚类方法)对含水层脆弱性进行了评价。结果表明,含水层脆弱区(易污染区)主要出现在沿渭河两岸及其较大支流的漫滩和低阶地,以及黄土台塬的洼地。评价结果与2001年地下水水质调查情况基本吻合,说明所建立的指标体系和评价标准合理。

| Abstract: | Using unconfined water in Guanzhong basin as an object to study,the influencing factors of groundwater vulnerability were analyzed,and the assessment index systems and criterions were established,and groundwater vulnerability was evaluated by the fuzzy Interactive Self-Organizing Data Analysis Technique (fuzzy ISODATA) method together with GIS technology.The assessment results show that groundwater vulnerable (easy to be polluted) areas in guanzhong basin appear at the floodplains and the lower terraces of Weihe River and its large tributaries,the depressions of the loess tableland.The assessment results are in accordance with the actual groundwater quality situation in the year 2001,so it showed the assessment index systems and criterions established are reasonable. |
