There are abundant fisheries resources in South China Sea which accounts for important strategy position in China.Associated with Beidou Positioning System,ARM advanced processor and NR flushbonading operating system,South China Sea fisheries information dynamic collection and automatic analysis system was established based on GPS,GIS and RS integration technology.It is a distributed system including four independent subsystems such as ship-borne fishing information realtime collection,South China Sea data integrated center,marine fisheries information system and deep sea fishing ground forecast subsystems.We invented ship-borne fishing data realtime collection terminal with the Beidou communication function.The on-spot message interplay was realized between the fishing vessels and land data center by Beidou short message channel.Moreover,the safe and stable data sharing between data center and the data analysis application system by VPN channel also came into being.Therefore,it resulted that the establishment of whole connection visualization network between the fishing vessels and the land data center.Based on this network,the fishing data were sent to the South China Sea GIS by the fishing vessels and the data analysis themes of the catch by fishing zones,vessels or species were analyzed and displayed immediately.Through several years' collection and analysis of the fishing,fisheries biology and fishing ground data,the purpleback flying squid fishing ground of South China Sea deep sea can be preliminarily forecast and be sent to the fishing vessels to improve their fishing efficiency.The 3S integration platform technology put forward the fast synthesis process of the South China Sea fisheries data and created a new circulation model between fishing vessels operations and the data research and digestion.It can be deduced that this 3S integration technology will play a more and more important role in the future sustainable fisheries development in South China Sea.
