摘要
宿州市是以地下水为主要供水水源的城市,地下水水质的优劣直接影响着当地居民的身体健康。通过对埇桥区内66个地下水样点EC、TDS值的测试,得出区域内TDS达标率为66.67%的结果,并运用Surfer绘制了区域内地下水硬度(由TDS表示)的平面分布图,发现该区地下水硬度分布具有中部高、南北两侧低的特征。结合该区工农业发展现状及地质背景,推断地下水硬度变化与人口密集程度有关,但目前尚不排除基岩埋深变化的影响。
Suzhou City is one of the cities whose main water source is groundwater,which is directly related to the health of local residents.Based on analysis of EC and TDS values of 66 groundwater samples in Yongqiao District,Suzhou City,the qualified rate of water TDS is proved to be 66.67%,and the horizontal distribution of groundwater hardness（expressed by TDS） was carried out by software（Surfer）,and is characterized by ＂high in middle relative to north and south＂ in the district.Moreover,combined with the situation of industrial and agricultural development and geological settings,the results attempt to support the idea that the horizontal distribution of groundwater hardness is controlled by the distribution of population density,although the depth of bedrock can not be ruled out at the moment.
