地下岩溶水环境质量评价模型研究

该文利用模糊数学和灰色理论的相关知识,根据地下岩溶水系统水化学动态特征和污染机理以及水文地质条件自身特点建立了地下岩溶水环境质量评价数学模型;并验证此模型,对西龙河峄山断层带水源地的地下岩溶水环境质量进行了综合评价。评价结果表明：该岩溶水系统大部分地区地下水的环境质量状况较好,局部地段较差,且地下水环境质量的分布特征与区域水文地质条件及水源地补给排泄关系具有较好的相关性。此结论与运用加权均值型指数评价法得到的结论相同,这说明此模型的建立是合理的,评价结果是完全可靠的。

Study on The Model of Karst Groundwater Environmental Quality Evaluation

Based on the character of water chemistry dynamic property, pollution mechanism and hydrogeological condition of karst groundwater system, we established the mathematical model of karst groundwater environmental quality evaluation, using the knowledge of fuzzy mathematics and grey theory. An assessment of karst groundwater environmental quality in the fault zone water source site in Yishan, Xilong River was used to verify this model. The results showed that the groundwater environmental quality was relatively good in most of areas, and bad in some parts; its distribution characteristics had a strong correlation with regional hydrogeological conditions and correlation of recharge and discharge in this water source sites. This solution was the same as that one from another evaluation method of weighted average index, which proved that the establishment of this model is reasonable and the result from this evaluation method is completely reliable.
