Multi-source monitoring and data fusion is becoming research hotspot in recent years with the demand of evaluation of early-warning for water quality is higher and higher.Data fusion is a technology that comprehensively processes multi-source data from multiple sensors to make decisions more accurate and reliable.This paper presents the research progress in data fusion and the application of multi-source data fusion in water quality monitoring at home and abroad,and explore sharing mechanism of the monitoring data for the smooth sharing of water environment monitoring information.Finally,the research on early-warning methods for water quality evaluation and the exchange and sharing of data are prospected from aspects of fusion methods,fusion software,storage methods and sharing platforms,in order to promote the theoretical and practical development of water quality evaluation early-warning method based on multi-source monitoring data fusion.
