在中国一些水资源短缺地区的承压含水层被大量开采。为了针对性地对其进行保护,该文对承压含水层脆弱性评价。通过阐释越流区承压含水层受到污染的原因,以承压含水层顶板处污染物浓度超过最大允许浓度的累计时间作为承压含水层特殊脆弱性指数,基于溶质运移方程,采用数值计算,得到承压含水层特殊脆弱性指数,从而避免了评价因子权重分配的任意性。以济宁市承压含水层脆弱性评价为例,对模型的可靠性进行了测试,其评价结果与该地区两年后总硬度升高值的分布状况吻合较好。 Confined aquifers in some of China’s water-scarce regions are being mined. In order to protect it in a targeted manner, this paper evaluates the vulnerability of confined aquifers. Based on the reason that contaminated aquifer in the confined aqueduct is contaminated, the cumulative time when the pollutant concentration in the confined aquifer exceeds the maximum allowable concentration is taken as the special vulnerability index of confined aquifer. Based on the solute transport equation, , We get the special vulnerability index of confined aquifer, so as to avoid arbitrariness of weight distribution of evaluation factor. Taking the evaluation of the vulnerability of confined aquifer in Jining as an example, the reliability of the model was tested. The evaluation results are in good agreement with the distribution of the total hardness increase two years later in this area.
