Abstract

Based on the survey data from 1975 to 1998 in the 32°N section,the distributions of temperature,salinity,dissolved oxygen and nutrients as well as their variation trends were analyzed during these 20 a.The climatet rend coefficients and the anomaly pictures of the factors revealed positive trends of nitrate.But dissolved oxygen,phosphate and silicate decreased in spring.The nutrient structure in spring was also discussed.The content of nitrogen was generally low and it was possible to be a limiting-factor for phytoplankton growth in the study area.
