Environmental factors, such as salinity, temperature, runoff, and tidal current influenced the temporal and spatial distributions of zooplankton in tidal creeks.

Biodegradation ways, mechanism and kinetics of alkanes, cyclanes and arenes are reviewed, and the influences of temperature, nutrients, oxygen and salinity on biodegradation are analyzed.

As the important factors of influencing sea ecological environment, the temperature and the salinity of sea water is the most important two parameters in the Marine environment monitoring.
