摘要
本文根据贵阳市近10年的地下水监测资料,采用传统统计方法对岩溶地下水水位、流量、水质动态特征进行了分析。结果表明:①岩溶地下水水位动态变化为多峰型、单峰型、平缓型三种年动态特征类型。②流量动态特征为锯齿型。③根据地下水质量标准(GB/T14848-93),对研究区8种易污染的离子进行统计发现硝酸盐、亚硝酸盐、氨氮3种离子浓度超标,地下水达到Ⅲ~Ⅴ类水,岩溶地下水受到不同程度的三氮污染。以上结论可以为该区今后岩溶水资源的可持续开发利用和保护提供依据。
According to monitoring data of groundwater in the last l0 years in Guiyang city, the dynamic characteristics of karst groundwater on water table, flow and water quality were studied. Through analysis, dynamic characteristics of water table were multi-peak type, single peak type and flat type. Dynamic characteristic of flow was zigzag type. On the basis of groundwater quality standards, there were three ion concentrations in excess of the quality standards. They were nitrate, nitrite and ammonia. On the other hand, according to analysis, it is found dynamic changes in relation to supply, run-off, drain, rainfall, topography and human activities.
