滕州荆泉水源地水文地质条件分析及防污性能评价

Analysis on Hydrogeological Condition and Antifouling Performance Evaluation of Jingquan Water Source Area

摘要:

荆泉水源地是滕州市城区的重要供水水源地，近年来随着国民经济的发展，水源地及其上游补给区人类活动的增多，其地下水质有逐渐变差的趋势，查明水源地水文地质条件、评价其防污性能，对开展水源地地下水环境保护、保障滕州市城区供水安全具有重要的意义。本文在充分分析水源地及其所在的水文地质单元——滕县东部丘陵谷地水文地质条件的基础上，分析了水源地水文地质条件的多年变化特征，采用COP法对荆泉水源地进行了防污性能评价并进行了防污性能分区，为水源地地下水的保护和动态监测提供依据。地下水防污性能高的区域位于水文地质单元北部岩浆岩变质岩山区，防污性能中等地区主要分布于水文地质单元的南部山区冲洪积平原，防污性能低区位于水文地质单元的东南部碳酸盐岩山区及其山麓一带。

Abstract:

Jingquan water source is an important water supply source in the urban area of Tengzhou city. In recent years, accompanying with the development of national economy, the water source and its upstream replenishment area have increased human activities, and its groundwater quality has a tendency to gradually deteriorate. It is of great significance to find out hydrogeological conditions of the water source and evaluate its anti pollution performance for the protection of groundwater environment and the safety of water supply in the urban area of Tengzhou city. Based on full analysis of the water source and its hydrogeological unit, that is hydrogeological conditions of the hills and valleys in the eastern hills and valleys of Tengxian county, hydrogeological conditions of the water source for many years have been analyzed. By using COP method, the antifouling performance of Jingquan water source has been evaluated, and the antifouling performance zoning is carried out. It will provide a basis for groundwater protection and dynamic monitoring. The areas with medium antifouling performance are mainly distributed in the southern mountainous alluvial plain of the hydrogeological unit. The area with low antifouling performance is located in the carbonate mountain area and its foothills in the southeast of hydrogeological unit.
