| Abstract: | To forecast the water quality at the definite range. Recurring to the common file, intersect the forecasting results and some geographic information by the powerful spatial analyses function of GIS, the methods and the flow of water forecasting are put forward by means of GIS. The research result indicates that the method is accurate and practicable, and has the highly extended value. |
