Abstract:

he relationship among organic salts,chlorophylla (chla) and physical properties of sea water was studied in this paper. The study contained three parts, the general analysis, the spatial autocorrelation analysis, and the comparison of density distribution. The results indicated that there is a difference between the spatial pattern of chla and that of organic salt, the heterogeneous distribution of organic salt vs. the random distribution of chla, the random distribution of organic salt vs. the aggregation distribution of chla. The environmental factors, which influence chla and primary production, are different at different month, no factor has special effect in December, the nitrate, ammonium, and surface temperature together influence the concentration of chla and primary production in Jan., the temperature is the main effective factor in February. Phosphate has little effect on the concentration of chla.
