水文地球化学反应-迁移-分异模型
HYDROGEOCHEMICAL REACTION-MIGRATION-DIFFERENTIATION MODEL
【摘要】 为水资源水质评价和环境水化学研究奠定理论基础和科学依据 ,将理论化学与传统水文地球化学融合在一起 ,运用三相平衡原理 ,矿物溶解的偏平衡理论 ,建立了典型水文地质蓄水构造的水文地球化学反应 -迁移 -分异模型 ,研究了蓄水构造内不同区带的主要化学反应 -迁移 -分异特点 ,探讨了水文地球化学分带代表性矿物 ,化学指标和水化学类型分带特征。全面系统地论述了补给区—补给迳流区—迳流区—排泄区 ,地下水中物质成分的形成和演化规律 ,并提出矿物饱和指数的新意义。实例表明 ,该模型具有理论和应用价值。
【Abstract】 To provide theory basis and science evidences to water resources quality assessment and environment chemistry research, theory chemistry and traditional hydrogeochemistry,three-phase equilibrium theory, partial equilibrium theory of minerals dissolve are used. Typical hydrological impounded structure hydrogeochemical reaction-migration-differentiation model is estimated.Main chemical reactions-igration-differentiation features of different zones in impounded structure are studied.Representative minerals,chemical indexes and hydroeochemical type zonation feature in hydrogeochemical zones are discussed.The formation and evolution laws of groundwater components from recharge area to tunoff region to region of outflow are discussed systematically.A new saturated index concept of mineral dissolve and precipitations is presented. The model usage shows that it has theory and applied value.
【Key words】 chemical reaction-migration-differentiation model; partial equilibrium theory; saturated index;
