By using trial observations data from Hulu island in Bohai,Pingtan island ,Dongshan island in East China Sea,Woody island in South China Sea during 2002-2008,physical parameters (characteristic refractive heights,refractive structure parameter values) as well as some relevant electro-optical system propagation parameters based on Bulk flux algorithm and ray tracing program are studied statistical in this paper. The accumulative probability of the positive characteristic refractive height in Dongshan island is above 90%,the percent of high refractive-index soructure parameter (C2n) values (C2n>10-14) is about 50%,which is higher than that in the Pingtan island and Woody island obviously. The cumulative probability of the optical horizon reduction greater than 4 km is close to 50% because of the subrefraction. Dongshan island and Hulu island are under the strong turbulence,the probability of the coherent length smaller than 15 cm is 60%,40% respectively. Its statistical result and the analysis method may provide the information for the marine electro-optical system test environment safeguard.
