基于土壤水热耦合运移基础理论构建水文地质数学规律模型

Construction of Hydrogeological Mathematical Law Model based on the Basic Coupled Migration Theory of Soil Water and Heat

土壤和水是将其他形式的水进行转化和运移的纽带和重要环节,而土壤中水和热的运移是相互作用的,基于土壤水热耦合运移基础理论构建水文地质数学规律模型并进行参数反演对于研究土壤水的相变及其他相关问题的研究具有重要意义。本文通过分析皖西丘陵地区的水热生态平衡系统,运用水热运移机理,构建水文地质数学规律模型并进行参数反演,结合皖西地区水文监测站数十年的蒸发和降水数据,进一步论证水文地质数学规律,为维持皖西丘陵地区生态平衡提供了理论依据。

Soil and water are the bond and important link for the transformation and migration of other forms of water,and the migration of water and heat in soil interact with each other.Therefore,the construction of hydrogeological mathematical law model and parameter inversion based on the basic coupled migration theory of soil water and heat play an important role in the study of soil water phase transition and other related problems.Based on the analysis of the water and heat ecological balance system in the west hilly area of Anhui,this paper constructs a hydrogeological mathematical law model and performs parameter inversion by using the mechanism of water and heat migration.Combined with the evaporation and precipitation data of the hydrological monitoring stations in the west Anhui for decades,this paper further demonstrates the mathematical law of hydrogeology,which provides a theoretical basis for maintaining the ecological balance in the west hilly area of Anhui.
