中文摘要:
      以上寨村朱家龙潭地下河1986、2010—2014年的水质测试数据为基础,研究地下河近30年来主要离子浓度变化规律,以期为裸露型岩溶山区地下水的保护提供科学依据。分析结果为近30年以来研究区大部分水化学指标浓度有明显的上升趋势,但是离子浓度季节变化规律性不明显。并采用地下水质量标准推荐的方法对近30年来的水质进行单项指标评价及综合评价,枯季综合评价结果为1986、2010—2014年中超标组分为F-、NH4+、Al3+、COD;2011—2013年超标组分为F-、NH4+、NO2-、COD;丰季综合评价结果为1986—2014年超标组分为F-、NH4+、NO2-、COD、TH、Al3+、Mn。主要是受水-岩地质作用过程、人类工程活动和区域地质环境变化的共同影响。
英文摘要:
      On the base of water quality data of Zhujialongtan underground river in 1986,2010 and 2014,main ion concentration changing tendency in the recent 30 years are studied,so it will afford scientific accordance for groundwater protection of bare karst mountainsThe result is most chemical concentration index in the target area rise obviously in recent 30 years,but the ion concentration changing tendency is not obviousBy use recommended groundwater quality standard method,the single and comprehensible assessment are proceed for the water quality in recent 30 years,the results show in the dry season,the excessive components are F-,NH4+,Al3+ and COD in 1986,2010—2014,the excessive components are F-, NH4+,NO2 and COD in 2011—2013In the wet season,the excessive components are F-,NH4+,NO2,TH,Al3+ and Mn in 1986—2014they are effected by water-rock geologic process,human engineering activities and regional geologic environmental change
