Popis:	Based on the data obtained in the coastal waters of Shenzhen from the Guangdong Environmental Monitoring Center,the distribution of DIN, DIP were analyzed, and the temporal spatial variations of nutrient level and organic pollution situation were evaluated using methods such as single factor index, eutrophication index,and water organic pollution evaluation index. The results show that the nutrient level of the eastern waters was lower than that of the western. The Dapeng Bay and Daya Bay comply with the first-class seawater standard, the Zhujiang Estuary and Shenzhen Bay exceed the fourth-class seawater standard. And there were some similarities between the eutrophication and organic pollution spatial distribution, and the eutrophication and organic pollution were observed in the western waters. The correlation analysis suggested there was a negatively correlation between salinity and major pollutants (P
