Groundwater numerical simulation of total hardness in Beijing suburb

摘要

Basing on groundwater quality data collected in Beijing and groundwater chemical characteristic, the paper studies the hydrogeochemistry law of groundwater total hardness of Beijing suburb in some methods such as groundwater solute transportation simulation and the geological statistics. Set up hydrogeology conception model, mathematic model and the three-dimensional groundwater total hardness transportation model. At last, the paper forecasts evolution trend of total hardness, which provides the scientific evidence for groundwater management.
