Abstract
This paper selects lake and river areas in Jinjiang City as the study objects. Eutrophication and dynamic change of water bodies are monitored via field fixed-point monitoring, according to different temporal and spatial monitoring data of a decade, using multi-temporal remote sensing image data processing technology and computer simulation method based on comprehensive nutrition index method. The monitoring results have shown that since 2006, Jinjiang water body has been at a mild eutrophication level, and with the passage of time, the overall situation had risen first and decreased afterwards from January to December. The establishment of corresponding water environment ecological monitoring protection and early warning mechanism is put forward to improve the ability of water quality monitoring according to the results of the dynamic monitoring.
