Hydrochemical Characteristics and Genesis of Guoliji Monoclinic Karst Water System in Shandong Province
摘要
Abstract
Guoliji monocline karst water system is one of typical karst water system in the low mountain and hilly area in middle and southern Shandong province.It has typical hydrogeological conditions,high inten-sity of groundwater development and utilization,and significant impact of human activities on hydrogeo-chemical characteristics.In order to systematically reveal chemical characteristics,spatiotemporal distri-bution patterns,and genesis mechanisms of regional groundwater,based on hydrogeological surveys,sys-tematic sampling and testing analysis have been carried out during the wet and dry seasons.By using mathematical statistics,Piper trilinear diagrams,Gibbs diagrams,end element analysis,chlor alkali index and principal component analysis comprehensively,chemical evolution characteristics and genesis of groundwater have been analyzed.It is showed that water quality in the study area is in the order of karst water＞pore water＞surface water.The water quality of groundwater in the dry season is better than that in the wet season.It is closely related to the infiltration of ions carried by precipitation during the wet sea-son.During the dry season of karst water,HCO3-Ca type and HCO3·SO4-Ca·Mg type are main types.During the wet season,HCO3·SO4-Ca·Mg type and HCO3·SO4-Ca type are main types.Hydrochemical types show significant seasonal variations.The formation and evolution of groundwater chemistry in this area are dominated by water-diagenesis and human activities,with cation exchange as a secondary influencing factor.关键词
