摘要
在分析广州市地理、水文、气候、地貌和水文地质特点的基础上,利用100个钻孔的抽水试验资料以及搜集的其他地质资料和水文地质参数,评价了广州市地下水资源量和允许开采量;利用47个生活民用井2012年丰枯两季的20项水质检测数据,评价了广州市五个重要地下水资源分布区的地下水质量;利用广州市2011年地下水开发利用数据,评价了广州市地下水资源开发利用情况。结果表明:广州市地下水资源丰富,水质总体较好;部分区域由于受到人类活动影响,出现细菌指标超标和氮污染;地下水开发利用量较少。在此基础上,提出了地下水管理对策。
Based on the analysis of geography, hydrology, climate, topography and hydrogeological characteristics of Guangzhou, in combination with pumping test data from 100 boreholes and other collected geological data and hydrogeological parameters, this paper assessed the amount and allowable withdrawal of Guangzhou City s groundwater resources; With the utilization of 20 water quality monitoring data from 47 civilian wells in both wet and dry seasons of 2012, this paper also evaluated the groundwater quality of Guangzhou City s 5 important distributions of groundwater resources; With the data of groundwater exploitation and utilization of Guangzhou in 2011, this paper also evaluated the amount of exploitation and utilization of Guangzhou City s groundwater resources; And the results showed that: Guangzhou abounded in groundwater resources; water quality was generally good, although Bacterial indicators failure to meet the standard and Nitrogen pollution appeared in some areas because of the effects of human activities; The groundwater resources of Guangzhou was lowly exploited. Finally, suggestions about groundwater management in the future were made to the relevant authorities.
