Maritime green habitation system and modularized construction method of same

The invention relates to a maritime green habitation system and a modularized construction method of the same. The maritime green habitation system comprises at least one floor unit, wherein each floor unit comprises at least one room, indoor furniture, a deck and solar photovoltaic plates, the room and the indoor furniture are formed through alignment and splicing of at least two modules, and the module has a standardized size; the deck is stretched outwards and installed on surrounding edges of the bottom face and the top face of each floor unit; and the solar photovoltaic plates comprise roof solar photovoltaic plates and side face solar photovoltaic plates. In the maritime green habitation system, the at least two modules are aligned and spliced at a construction site to form the room and the indoor furniture of each floor unit, and the deck and the solar photovoltaic plates are installed, so that the maritime habitation system can be built in a short time, construction duration is greatly shortened, and construction cost is reduced.
