广州临空经济示范区地下水环境探讨

基于广州临空经济示范区水文地质条件,就地下水开发利用现状、地下水污染源、主要环境水文地质问题等方面分析了广州临空经济示范区地下水环境现状。通过民井水样分析数据得出:区内主要环境水文地质问题表现为三种:区域性天然不良水质,主要表征为地下水质pH值偏高;由于农业用地或局部工程建设引起的地下水位下降;地下水铝、铅、锰含量偏高。

Analysis on the Present Situation of Groundwater Environment in Guangzhou Airport Economic Demonstration Zone

Based on the hydrogeological conditions of Guangzhou Airport Economic Demonstration Zone,the status quo of groundwater environment in Guangzhou Airport Economic Demonstration Zone is analyzed in terms of groundwater development and utilization status,groundwater pollution source and main environmental hydrogeological problems.The main environmental hydrogeological problems in the region are manifested in three types:poor quality of regional natural water,which is mainly characterized by high groundwater quality pH value;the decline of groundwater level,due to agricultural land or partial engineering construction;high content of the groundwater aluminum,lead and manganese.
