新乐市地下水防污性能评价

Evaluation of Groundwater Antifouling Performance in Xinle City

【目的】新乐市地下水资源丰富,为保护地下水资源,保证人民饮用水安全,研究地下水防污性能评价具有重要意义。【方法】采用DRASTIC评价方法,选取反映水文地质条件的7个参数:地下水埋深、含水层净补给量、含水层岩性、土壤介质类型、地形坡度、包气带岩性及含水层水力传导系数等对新乐市地下水防污性能进行评价。【结果】新乐市分为防污性能较好区、防污性能中等区和防污性能较差区,该区域划分较为客观,符合现状。【结论】为各级决策部门的合理规划,保护地下水资源提供简单明了的科学依据。

[Purposes]Xinle City is rich in groundwater resources.In order to protect groundwater resources and ensure the safety of people′s drinking water,it is of great significance to study the evaluation of groundwater antifouling performance.[Methods]In this study,the DRASTIC evaluation method was used to select seven parameters reflecting the hydrogeological conditions:groundwater depth,aquifer static recharge,aquifer lithology,soil type,topography,unsaturated zone influence and aquifer conductivity coefficient to evaluate the groundwater anti-fouling performance of Xinle City.[Findings]Xinle City was divided into good antifouling performance area,medium antifouling performance area and poor antifouling performance area.The results were objective and in line with the current situation.[Conclusions]This paper provides a simple and clear scientific basis for the rational planning of decisionmaking departments at all levels and the protection of groundwater resources.
