Anti-trawling marine environment comprehensive observation system and laying and recycling method thereof

The invention relates to an anti-trawling marine environment comprehensive observation system and a laying and recycling method thereof. The anti-trawling marine environment comprehensive observation system comprises a seabed base and a navigation buoy. Wherein the seabed base is arranged at a preset position of the seabed of a to-be-observed ocean, and observation equipment is arranged on the seabed base and is used for synchronously and continuously observing multiple ocean elements such as ocean waves, ocean currents, water levels, temperature and salinity, mud temperature and the like for a long time; the navigation buoy is connected with the seabed base through an anchor chain or a steel wire rope and used for warning and expelling the fishing boat so as to reduce damage of the trawl net to the seabed base and observation equipment, and the protection effect is achieved. The method can be widely applied to the field of ocean observation. 本发明涉及一种防拖网海洋环境综合观测系统及其布放回收方法，其包括：海床基和导航浮标。其中，海床基设置在待观测海洋海底的预设位置处，且海
