The invention discloses a yhree-dimensional mobile monitoring system for a sea area hydrate exploitation environment, which comprises a mobile monitoring platform and a control unit thereof. The mobile monitoring platform comprises a main cabin body, and an environmental parameter monitoring unit, a topographic parameter monitoring unit, a cruise monitoring unit and a sampling unit which are arranged on the main cabin body and used for monitoring the surrounding environment and topographic changes of the drilling platform. An anchor system subsurface buoy working unit is further arranged behind the main cabin body, the anchor system subsurface buoy working unit is used for monitoring environmental parameters such as methane content and turbidity abnormity, and the anchor system subsurfacebuoy working unit stays at any height for monitoring under rotation of the winding vehicle. According to the system, various environment and other parameters are monitored in an omnibearing and three-dimensional mode in the circumferential direction and the vertical direction with each production well as the circle center, the situation that various cables are laid on the seabed or a workstation is established is avoided, the environmental effect of hydrate exploitation activities is comprehensively and effectively evaluated, potential environmental disasters are early warned in advance, and potential safety hazards are avoided. and a scientific evaluation system in the aspect of environment is provided for commercialized hydrate exploitation.
