Spatial digital analysis for regional water environment impacts by monitoring data with GIS

Water resource is very important in modern society for the life and production, its management decision made by decision-makers should focus on the quality of water body, so the spatial distribution of water quality is needed to analyze. GIS software has strong spatial analysis functions, after binding the monitoring data with spatial points, we can comply with the data by GIS and analyze the spatial information by computer. AreView made by ESRI, can help us setup the spatial database, then apply the spatial analysis function to acquire the distribution maps and contours of pollutants in water body, finally changing the legend in accordance with surface water environmental criteria, we can acquire the assessing results and forewarning map. In the case study, we selected a reservoir as research object, successfully come true the spatial digital analysis for water environment impacts by monitoring data, and acquired the water quality distribution and its forewarning maps.
