Poyang Lake Water Quality Model for Dynamic Prediction

Due to the establishment of Poyang Lake National Nature Reserve, we pay more attention to water pollution, so it is important to improve early warning mechanisms. My article will analysis the main source of Poyang Lake water quality parameters, establish gray GM(1,1)model, through the river into the lake water quality data to predict the water quality of Poyang lake area .Inspect after get results predicted by the model, the maximum variance ratio C = 37.7284%,a good prediction accuracy .The model can play a guiding role to the environment of Poyang Lake Ecological Reserve and biological conservation .
