Research on surface water quality navigation monitoring based on GIS
In the field of water quality and ecological environment monitoring,high-tech such as un-manned monitoring vessels were introduced,and multi-parameter analyzer and flow injection analysis equipment were used.At the same time,underwater side-scan sonar technology and manual inspec-tion methods were used to implement all-round,high-density real-time and on-site water quality monitoring in a river section in Zhejiang.The results showed that the water environment quality status of the monitored river section could be comprehensively and quickly obtained by the navigation moni-toring,and the concentration trend of each indicator was drawn by using geographic information sys-tem(GIS)data.Combined with the results of on-site sonar scanning and manual investigation,the polluted areas,main pollution factors and possible pollution sources of the river section were screened out,which provided a more detailed and reliable basis for precise pollution control and effective im-provement of water environment quality.
