摘要: 系统采集了鄱阳湖周边地下水,分析测定各单元的水化学参数.结果表明,环鄱阳湖浅层地下水整体偏酸性,呈低矿化度,局部地区出现微咸水.环鄱阳湖浅层地下水丰、枯水期的优势阴离子为HCO3-,阳离子为Ca2+和Mg2+.运用SPSS软件做离子相关性分析,各离子间均呈正相关性,说明可能有相同的来源.地下水的水化学类型整体表现为HCO3-Ca-Mg型,丰水期相对于枯水期出现较多的NO3-型和SO42-型水体,局部区域优势阴离子改变,出现了NO3-型、Cl-型地下水,可能受到农业化肥和工业废水排放的影响.整体上地下水的水化学类型受当地岩石类型的影响比较大,个别地区受人为的活动干扰较为强烈.

Abstract: The hydro-chemical parameters in the shallow groundwater around Poyang Lake were studied. The results showed that the shallow ground waters around Poyang Lake were of weak acid and low salinity, and part of the area had slight saline water. HCO3- was the predominant anion, while Ca2+ and Mg2+ were the predominant cations. SPSS software's correlation analysis showed that the ions had a positive correlation with each other, which indicated that the ions may have the same source. The groundwater belonged to HCO3-Ca-Mg type in the study area. NO3--type and SO42--type water appeared more in the wet season compared to the dry season. And the dominant anion changed in some areas, and the NO3--type and Cl--type water appeared, which may be affected by the agricultural fertilizer and industrial wastewater discharge. The chemical types of the shallow groundwater were influenced by local geology and rock types mostly. However, individual regions were strongly affected by human activities.
