人类活动影响盘龙江下游浅层地下水水质的变化

Change of the shallow groundwater quality by human activities influence in lower reaches of Panlongjiang River

根据盘龙江下游浅层地下水水质监测数据,通过对离子浓度、矿化度和水化学类型的分析,发现昆明市区北部人类活动对地下水的影响程度不断加强;市区则因为市政设施的建设,地下水变化趋于稳定;滇池草海北端因为治理强度加大,使地下水水质不断好转,而南部的湖滨平原,因为农业活动的影响,使地下水水质不断恶化。这些均表明人类活动在很大程度上影响了浅层地下水的水质。

Based on the monitoring data of shallow groundwater quality in downstream of Panlongjiang River, through the analysis of ion concentration,mineralization,chemical types, have discovered that the influence degree of human activities to the groundwater was getting strength- ened continually in the north urban areas of Kunming. Because of the construction of municipal facilities in urban area, the variation of groundwater quality was stability. In Caohai area, the groundwater quality was getting better because of enhancing the improvement intensity; but in south of littoral plain, the groundwater quality was getting worse due to agricultural activities. These shown that human activities influenced the shallow groundwater quality at a great degree.
