The Distribution of Microbes along the Coast of Shanghai and its Relationship with Environmental Factors

Microbes play multiple roles in the marine ecosystem, with a variety of functions. Luchao Port, Yangshan Port and Waigaoqiao Port are three major ports near the coast of Shanghai, and it is necessary to study the abundance and water environment of microbes. The distribution of hydrological and chemical characteristics shows that the distribution of temperature, salinity, dissolved oxygen and nutrient salt exhibit certain seasonal characteristics in the surface waters. Correlation analysis indicates that the temperature of surface waters is positively correlated with the number of microbes, but not very clear; salinity is significantly positively correlated with it; dissolved oxygen is negatively correlated with it; the correlation between nutrient salt and abundance of microbes is complicated, but not very significant (P> 0.05).
