Construction of dissolved oxygen rolling forecast and early warning platform based on LSTM——Taking the typical reaches of the Pearl River Delta as an example
Dissolved oxygen is a comprehensive index to measure water environmental quality and a key factor affecting water environmental quality standards in the Pearl River Delta in recent years.It is of great significance for regional water environmental management to achieve accurate prediction of dissolved oxygen and embed it into environmental decision support system.Considering that the traditional mechanism model is complicated to calculate and difficult to obtain the required data,it is not suitable for intelligent water quality prediction in the era of big data.Therefore,a Long Short Term Memory(LSTM)model was constructed by using the continuous observation data of automatic water quality section stations.The model realized the rolling forecast of dissolved oxygen in typical river reaches of the Pearl River Delta.Decision Support Platform for Comprehensive Management of Dissolved Oxygen in Typical Reaches of the Pearl River Delta was designed and developed according to the specification of data layer,application layer and presentation layer.The platform could intuitively and dynamically display the spatial and temporal changes of dissolved oxygen in the Pearl River Delta in real time,and perform hierarchical early warning based on the prediction results of dissolved oxygen,which would provide scientific and effective technical support for regional water environmental management.
