Study concentration in Sanya Bay by shipboard survey data at 12 showed that parts of the sea area have been polluted in stations from 2006 to 2008, and discussed the relationship different degrees, and some of them were very serious, between chl-a distribution and influential factors using such as the estuary and the harbor [8]. Researches have MOD[S sea surface temperature (SST), sea surface wind been carried out about the biology resource and ecology (SSW) and rainwater runoff data. Results showed that the environment in Sanya Bay [1,6,9,10-13]. However, here is chl-a concentration in Sanya Bay ranged from 0.30 to 13.58 3 lacking of longtime variability of chl-a and it's correlative mg'm- , the average concentration and standard deviation 3 3 factors. The main aim of the present study was to (SD) were 1.49 mg'm- and 1.74 mg'm- respectively.
