A Study, Supported By MIS For Water Resources & Water Environment, Of The Chemical Charactertics Of Karst Water In Yangcheng Country

For a start in this paper, a profile is presented of the natural geography, geology and hydrogeology in Yangcheng County, and, based on the synthetic consideration of the minerals consisting of carbonate rocks, geological tectonic and hydrogeological conditions, a general simplified multipurpose model is set up for the study of geology, hydrogeology and hydrogeochemistry in Yangcheng, then, an MIS is developed and set up for the water resources and water environment in Yangcheng Country, and standard, systematic and scientific management is carried out on the information and data relating to its natural geography, geology, hydrogeology, waterresources and water environment. After that, by combining themethods of chemical-thermodynamics and chemical-kinetics the zonary hydrochemical characteristics in the 3-D balanced system of gas, water and rock are outlined, and the reasons for zoning is also analyzed. On this basis, the hydrogeological and hydrogeochemical environment in Yangcheng is zoned, and, lastly, preventative measures are put forward for the utilization and protection of the headwaters and for the environmental pollution there.
