The general aim of the coastal wetland ecological restoration is to gradually restore the structure and the function of the existing degraded wetland ecosystem by adopting proper ecological, biological and engineering technologies, and finally achieve the self-maintenance state of the wetland ecosystem. When the coastal wetland is subjected to ecological restoration, proper pioneer plants are selected according to the ecological niche principle, and synchronous restoration of soil, vegetation and organisms is realized. The artificial method for recovering and reconstructing the wetland is an important measure for the ecological recovery of the coastal wetland. In the natural protection area of Louisiana Sabin and the region of Texas coastal zone of America, the technology of the ladder-shaped wetland is utilized to build the slope-slowing wetland in the shallow sea area, the spartina alterniflora and other wetland vegetation are planted on the constructed wetland, and the constructed ladder-shaped wetland can weaken the impact of sea waves, promote the sediment deposition and protect the beach, and can also provide a habitat for marine organisms. The river bin (2020) designs a restoration scheme for the habitat of the saline marsh wetland reed-suaeda heteroptera by taking the reclamation type degraded saline marsh wetland in the open country marine park as an example, and proposes to carry out the restoration of the habitat of the saline marsh wetland from two aspects of dam demolition and micro-topographic reconstruction according to the diagnosis and suitability analysis of the habitat problems of the wetland. At present, great progress is made in coastal wetland restoration at home and abroad, but the research is mainly focused on restoration of single factors such as terrain, landform, vegetation and the like, and the systematicness and integrity of ecological system restoration are not considered. In order to improve the sustainability and success rate of coastal wetland ecological restoration, the influence of hydrology, soil and organisms on wetland vegetation restoration should be comprehensively considered.
The Suaeda salsa wetland at the coast of the Liaohekou is an extremely important ecological resource in China, and has very important influence and effect in the aspects of adjusting regional climate, enhancing flood control and drought resistance, controlling pollution, improving wetland environment, increasing income of tourism industry and the like. In recent years, the phenomenon that vegetation areas of suaeda heteroptera in suaeda heteroptera wetland are greatly attenuated and dead has serious influence on the wetland function and the ecological tourism value in the Liaoning hydrone district of Panjin. In order to protect the precious resource of suaeda heteroptera wetland at the mouth of Liaoning river, a practical ecological restoration technology is urgently needed to carry out artificial restoration on the seriously degraded suaeda heteroptera wetland photosea areas.
