Key technology of water environmental data sharing platform -With the sample of Liao River Basin in China

Water environmental problems of river basins in china are becoming more and more serious. Whereas, the environmental watchdogs at different levels provide comparatively independent water environmental data and use various kinds of data patterns, which makes it difficult to resolve the problems in a comprehensive way and make a unanimous decision as to how to deal with the worsening water environment. To meet the requirements of Water Project, one of National Major Technological Projects, priority should be given to setting up integrated water environmental data sharing platform so as to solve the water environmental problems. This paper fully makes a research on the key technology of water environmental data in the following aspects: sharing network, sharing security, sharing management and sharing service, etc. This study has brought good results by taking Liao River Basin as a sample.
