The invention relates to a tide-driven heat collection and storage type greenhouse solar pool water storage method, which comprises the steps of building a water reservoir, filling, operating and maintaining. The constructed water storage system integrally comprises a heat collection pool, a circulation pool, a seawater supply system and a greenhouse, wherein the heat collection pool and the circulation pool form a water reservoir main body. The seawater enters the main water inlet pipe after energy dissipation through an energy dissipation pool under the driving of the tide so as to respectively supply water to the heat collection pool and the circulation pool. The greenhouse is arranged above the water reservoir main body and covers the whole reservoir. After the water reservoir is built, the reservoir is filled with primary pool water, then enters a stable operation stage, and is regularly maintained. The greenhouse solar pool water storage method has the beneficial effects that thesolar pool heat collection and storage and the greenhouse heat preservation are combined, so that the water temperature requirement of the coastal farm in winter can be ensured, the tide is adopted to drive the water supply so as to ensure that the water reservoir is timely updated and the water quality is fresh, the water reservoir can run for a long time without primary energy sources such as coal, oil and the like. According to the greenhouse solar pool water storage method, fresh seawater with moderate temperature can be provided for coastal mariculture farms in winter, and has wide research and application prospects.
