Aiming to improve the accuracy of predicting aquaculture wetlands derived greenhouse gas emissions, built on rough sets, a new model for predicting aquaculture wetlands derived greenhouse gas emissions is designed.The data of greenhouse gases in aquaculture wetland were collected and normalized.Based on the processed data, the gas emission relationship model of aquaculture wetland greenhouse was constructed.The rough set theory is used to construct a model for predicting aquaculture wetlands derived greenhouse gas emissions.So far, the prediction of aquaculture wetlands derived greenhouse gas emissions is realized.The experimental results show that the prediction model based on rough set improves the prediction accuracy and reduces the prediction time.
