Habitat restoration structure of tidal wetland
The invention discloses a habitat restoration structure of a tidal wetland and belongs to the habitat restoration technology. According to the technical scheme, the structure comprises an outer dam, an inner dam, an outlet culvert and an inlet culvert. The inner side of the inner dam is provided with a restoration area, and tidal water flow exists on the outer side of the inner dam; the restoration area is between the outer dam and the inner dam; the outer dam is higher than the inner dam; the inlet culvert is formed in the high position of the inner dam; the outlet culvert is formed in the low position of the inner dam; the bottom elevation of the inlet culvert is higher than the average tide level of the tidal water flow, and the top elevation of the inlet culvert is lower than the average tidal level of the tidal water flow; the bottom elevation of the outlet culvert is higher than the average tidal level of the tidal water flow, and the top elevation of the outlet culvert is lowerthan the average tide level of the tidal water flow; and a water gate is arranged at an outer outlet of the outlet culvert, so that water in the restoration area can flow out from the outlet culvert but cannot flow into the restoration through the outlet culvert. By applying a simple culvert structure, tides are reduced, the tide evolutionary rule of the tidal wetland is restored, and then the ecological environment of a tidal habitat is restored.
本发明属于生境修复技术的一种潮汐湿地的栖息地修复构造，技术方案为：该构造包括外坝、内坝、出口涵洞和入口涵洞；内坝的内侧为修复区，外侧为潮汐水流；外坝和内坝之间为修复区；外坝的高度高于内坝的高度；内坝高处设有入口涵洞；内坝低处设有出口涵洞，入口涵洞的底高程高于潮汐水流的平均潮位，顶高程低于潮汐水流的平均高潮位；出口涵洞的底高程高于潮汐水流的平均低潮位，顶高程低于潮汐水流的平均潮位；出口涵洞的外侧出口设置水闸，使修复区内的水体可通过出口涵洞流出，但不能通过出口涵洞流入。其运用简单的涵洞结构削减潮汐，恢复潮汐湿地的潮汐演替规律，进而修复潮汐栖息地的生态环境。
