Document Type and Number:
WIPO Patent Application WO/2023/125474
Kind Code:
A1
Abstract:
The present invention relates to a wetland function restoration system under the constraint of flood diversion and retarding in an estuary area. The system comprises a water intake unit, a water output unit, a reinforced purification area, and a natural purification area. The water intake unit comprises a water intake gate, an incoming water sedimentation pond, a water distribution main channel, and a water intake main channel, wherein the water intake gate is used for leading in water of a river section, the incoming water sedimentation pond is used for sedimenting silt of the incoming water, the sedimented water is then distributed through the water distribution main channel, and the water intake main channel guides the water in the water distribution main channel to enter the reinforced purification area; a multi-paddy field running water chain wetland in the reinforced purification area receives the water from the water intake main canal, and leads purified water into the natural purification area; there are seven habitats in the natural purification area; and the water output unit comprises a water outlet main channel and a water outlet gate, wherein the water outlet main channel guides the water in the natural purification area to enter the water outlet gate, and the water outlet gate pumps the water to enter the river or the lake. According to the present invention, the function of flood storage and detention of the estuarine wetland can be improved, the self-adaptation, self-recovery, and self-regulation capabilities of the wetland can be improved, the wetland can be restored while the water quality is purified, and a healthy wetland ecological system is constructed.
