摘要
On the basis of a large number of water quality monitoring data,the pollution situation of karst water was analyzed, two tendencies of groundwater pollution are predicted by means of numerical method under the circumstance of the polluting sources being controlled or the polluting sources still existing, and the impact of water pollution on water source is analyzed too. So, it thus clear that polluting sources treatment is of important role to slow down the diffusion of contaminants. The predicted results can be chosen as the basis for groundwater protection and pollution control.
