The invention provides a method for creating ecological
wetland to promote
water body exchange of an encircling type harbor basin or harbor. A
water storage water area is established nearby the harborbasin and communicates with
seawater, a gate is arranged on the side, and a
water body channel is arranged between the
water storage water area and the harbor basin or harbor. During
flood tide, thegate is opened, and the
seawater flows into the
water storage water area. During falling tide, the gate is closed, the
seawater flows into the harbor basin or harbor from the water storage water areato form harbor penetrating flow, and the polluted
water body in the harbor basin or harbor is driven to flow out of the harbor basin or harbor. The
natural power of tide fluctuation is utilized, wateris stored in the water storage water area during
flood tide, the water body in the water storage water area flows into the harbor basin or harbor through the water body channel during falling tide, the harbor (bay) penetrating flow is formed, and the key technical problem about the
water source water volume of the harbor (bay) penetrating flow is effectively and economically solved. Meanwhile, the method serves as an important measure for ocean resource
sustainable development and utilization and
ocean environment protection, the water storage water area can be established into the ecologicalwetland environment or created into the hydrophilic space.
