| 中文摘要: |
| 康保地区位于京西坝上高原生态防护区，供水水源以地下水为主。研究康保地区富锶地下水水化学特征及成因机理，对当地发展乡村振兴特色产业，以及坝上高原生态防护区水资源利用结构、效应优化具有积极意义。本文基于康保县水文地质条件，采集测试了 40件水样，通过 SPSS数理统计分析、Gibbs图及 Piper三线图等方法，分析了康保地区地下水水化学的组分特征、参数相关性和类型，讨论了富锶地下水控制因素和成因机理。结果表明:(1)康保地区富锶地下水分布较广，锶含量较高，最大值可达到 1.874 mg/L，Sr2+含量与 TDS呈显著正相关，“HCO3 型和 HCO3--Cl-型”是区域内富锶地下水主要水化学类型；(2)c(Cl-)/c(Ca2+)-比值介于 0.11～2.07，指示康保地区水动力条件较差，地下水径流循环缓慢，滞留时间较长，促进锶与围岩中 Ca2+、Mg2+以及 Na+、K+离子充分交换；(3)坝上高原康保地区气候干旱，富锶地下水受气候降水、地形地貌、地层构造多因素控制，大气降水自北部低山、丘陵区基岩风化裂隙带下渗补给，向中-南部经风化裂隙带和断裂破碎带侧向径流运移，该过程中水岩作用导致锶富集。本研究成果可为坝上高原康保地区富锶地下水开发和优化水资源利用结构提供科学参考。 |

| The Kangbao area is located in the ecological protection zone of the Bashang Plateau in western Bei.jing, with groundwater as the main source of water supply. Studying the hydrochemical characteristics and genesismechanism of strontium rich groundwater in the Kangbao area is of positive significance for the development of localrural revitalization industries and the optimization of water resource utilization structure and effects in the BashangPlateau ecological protection zone. This article is based on the hydrogeological conditions of Kangbao County, andcollected and tested 40 water samples. Through SPSS mathematical statistical analysis, Gibbs diagrams, and Piperthree line diagrams, the composition characteristics, parameter correlation, and types of groundwater hydrochemis.try in Kangbao area were analyzed. The controlling factors and genesis mechanisms of strontium rich groundwaterwere discussed. The results show that: (1) The distribution of strontium rich groundwater in Kangbao area is wide,with a high strontium content, with a maximum value of 1.874 mg/L. The Sr2+ content is significantly positively corre. lated with TDS, and "HCO3 type and HCO3--Cl-type" are the main hydrochemical types of strontium rich ground. water in the region. (2) The ratio of c(Cl-)/c(Ca2+) ranges from 0.11 to 2.07, indicating poor hydrodynamic conditionsin the Kangbao area, slow groundwater runoff circulation, and long retention time, promoting the full exchange ofstrontium with Ca2+ , Mg2+ , Na+ , and K+ ions in the surrounding rock. (3) The climate in the Kangbao area of theBashang Plateau is arid, and the strontium rich groundwater is controlled by multiple factors such as climate precipi.tation, topography, and geological structure. Atmospheric precipitation infiltrates and replenishes from the weath.ered fissure zones of the bedrock in the northern low mountains and hilly areas, and flows laterally through theweathered fissure zones and fractured zones in the central and southern regions. During this process, the water rockinteraction is the key to strontium enrichment. The results of this study can provide scientific reference for the devel.opment and optimization of water resource utilization structure of strontium rich groundwater in the Kangbao area ofthe Bashang Plateau. |
