METHOD FOR MONITORING THE QUALITY OF WATER AT WATER SOURCE

摘要

A method for monitoring the quality of water at a water source, comprising the following steps: step 1: determining a target water source, and constructing a water flow model by using remote sensing data from an observation satellite; step 2: evaluating various water quality elements of the water source according to an ecosystem stability degree, an ecosystem loss degree, and a risk degree of a risk source of the water source; step 3: performing overall safety level evaluation on the quality of water at the water source according to the water flow model on the basis of a fuzzy mathematical method; step 4: presetting a water quality migration distribution model of the water source according to the local meteorological environment and geological conditions; and step 5: establishing an early warning mechanism and an emergency mechanism by using the water quality migration distribution model of the water source. In this way, a wide range of surface water sources can be quickly and conveniently monitored and evaluated; furthermore, obtained monitoring results have the advantages of both spatiality and dynamics, thereby facilitating management of the water sources and prediction of pollution status.
