关中盆地高塘镇地下水水化学特征与水质评价
Hydrochemical Characteristics and Quality Evaluation of Groundwater in Gaotang County in Guanzhong Basin
摘要
Abstract
Groundwater resource is main water supply source in Weinan area.It plays a vital role in region-al social and economic development.By systematically collecting groundwater and river samples in Linwei area and Huazhou area in the south of Weihe River,combining with local hydrogeological conditions,hydrochemical characteristics,excess ions and water quality of different water samples in the study area have been evaluated comprehensively.The hydrochemical types of groundwater and surface water in the study area gradually transform from HCO3-Ca type to HCO3·SO4-Na·Mg type from Qinling bedrock mountainous area to the south bank of Weihe river.The main controlling factors for hydrochemical types of groundwater in the region are mainly dissolution filtration and evaporation concentration.The groundw-ater quality in the area is mainly class Ⅰto class Ⅲ.The proportion of water samples with excellent water quality in diving is 88.9%,while the proportion of water samples with excellent water quality in pressur-ized water is 82.8%.The dominant ions in water are HCO3 and Ca2+,and the excessive ions mainly in-clude total hardness pH,nitrates and soluble total solids.It is indicated that the overall quality of ground-water in the study area is good.It is mainly composed of Mainly freshwater.The research results can pro-vide a basis for comprehensive management of water resources and high quality development of ecological environment in Guanzhong basin.关键词
