Water environment monitoring and information management of closed water body has always been an important link to enhance the functions of a modern city.It is an important part of the healthy development of a city.Modern remote sensing technology has been used in surveying and providing urban water environment information combined with GIS spatial analysis and information management capabilities of closed water bodies such as lakes and reservoirs.It is an important and indispensable tool for modern water environment management of lakes and reservoirs.In this paper,three monitoring methods are argued.Firstly,with the use of satellite image,aerial photography and other means providing all-weather,omni-directional,multi-bands,multi-temporal remote sensing image information,the water temperature,total suspended solids,particulate matter,chlorophyll,transparency (turbidity),thermal pollution and other information could be obtained;secondly,with integrated methods of laboratory testing,water quality monitoring sites,the cross-section of the routine monitoring of benzene,phenol,COD,ammonia nitrogen,total phosphorus concentrations could be assessed;thirdly,with the use of online monitoring of toxic chemical substances,the arsenic,mercury concentration could be monitored.The establishment of space-ground integrated monitoring system of closed Water bodies is the most efficient way to promote means of using three types of monitoring data and analysis capabilities for water environment management of closed water bodies,so as to provide an effective basis for information management and decision-making.
