Coastal wetland ecological revetment technical system for human and environmental needs

Abstract

The invention discloses a process method of a coastal wetland ecological revetment technical system for human and environmental needs. The system comprises an ecological dam, a constructed wetland system, a purification pond, and a data monitoring and automatic control system. The method comprises the following main process steps: A) building a dam; B) forming openings in a side slope of the dam, connecting a constructed wetland, forming a natural wetland ecological system in the constructed wetland, and keeping a specific community structure of a coastal wetland ecological system on the wetland; C) leading sewage into the purification pond if a pollution incident happens, and discharging the sewage after treatment in a clear water reservoir, wherein one purification pond is additionally built every 500 meters of the length of a seawall; D) opening a valve on the purification pond to communicate with the constructed wetland if no pollution incident happens to enable the constructed wetland ecological system to be communicated with a natural wetland area and the sea; E) introducing living things into the constructed wetland, and providing a good growing space for the living things so as to form a complete interlaced zone ecological system food web; and F) monitoring related environmental parameters in real time by using the automatic control system.

Description

technical field [0001] The invention belongs to the field of environmental science and engineering application, and specifically relates to a process method of a coastal wetland ecological bank revetment technology system oriented to the needs of human beings and the environment. The combination of coastal engineering can not only protect the stable operation of the original natural ecosystem in the intertidal zone, but also reduce the erosion of waves on dam structures and reduce the erosion of offshore engineering structures. Background technique [0002] Coastal wetland itself is an interlaced ecosystem with common characteristics of land and sea, rich in natural resources and complex ecological interaction process. In recent years, due to the intensification of urbanization in coastal areas, especially in some estuary wetland areas, in order to prevent the flooding of spring tides, high tides and storm surges, as well as the invasion of wind and waves and land submersion...

AI Technical Summary

Problems solved by technology

[0009] In actual work, the coastal wetland ecological bank revetment technology that takes into account the above four functions has not been fully developed. Many ecological bank revetment technologies that have been proposed are only planting plants on the slope and increasing the roughness coefficient of the slope, and cannot achieve multi-functionality. Integration, the physical barrier of the ecosystem still exists, and the protection of the unique ecological functions of the wetlands is not thorough, without considering the self-purification function of the water body, it cannot be a complete system
