Problems solved by technology

However, the open beach is the most widely distributed type of beach in the coast and is the most harmed by typhoons. However, the research on the restoration of mangroves on open beaches is still blank at home and abroad, and there is no mature and effective open beach. Mangrove Restoration Techniques

[0044] This embodiment provides a beach ecological restoration method. During the implementation of the method, a beach comprehensive protection system 100 will be constructed. See figure 1 As shown, the method includes the following steps:

[0045] S1 builds the coastal ecological protection embankment 110: first, lay a layer of permeable geotextile on the beach between the protected object 200 and the ocean, set the bottom protection and foundation bed sequentially on the permeable geotextile, the bottom protection is a piece of stone with a width of 9.5m, The foundation bed is a block stone with a thickness of 30cm and a weight of 80kg. Next, transport the prepared multiple concrete blocks 111 to the site, use a crane to lift each concrete block 111 in turn, place them on the foundation bed along the coastline, and finally splice them into a coastal ecological protection embankment 110, a coastal ecological protection embankment 110 along the coast Shoreline layout, the ba...

Abstract

The invention provides a comprehensive sand beach protection system and an ecological sand beach restoration method and relates to the field of coastal ecological environmental treatment. The method comprises the steps that firstly, a coastal ecological protective embankment is formed by sequentially splicing multiple concrete blocks on the sea beach between a protective object and the ocean and is arranged along a coastline; secondly, soil improvement is conducted on the area behind the coastal ecological protective embankment by adopting the mode of changing sand with soil to form an artificial mud flat; thirdly, mangrove forests are planted on the artificial mud flat, and a mangrove forest protection net is arranged around the mangrove forests, wherein the density of the mangrove forests is 5000-7500 plants / hm<2>. By the adoption of the method, the comprehensive sand beach protection system consisting of the coastal ecological protective embankment, the artificial mud flat, the mangrove forests and the protection net and integrating wave prevention, sand transportation and an ecological mangrove forest system is established, effective restoration of the opened sand beach mangrove forests is achieved, and coastal typhoons, waves and ecological environment are comprehensively treated by adopting measures according to local conditions.

Description

technical field [0001] The invention relates to the field of coastal ecological environment management, in particular to a beach comprehensive protection system and a beach ecological restoration method. Background technique [0002] Mangroves are woody plant communities naturally distributed in the intertidal zone of tropical and subtropical coasts. It is a unique ecosystem different from terrestrial ecosystems and marine ecosystems. The environment plays an irreplaceable role. Mangrove itself is a precious germplasm resource, which is of inestimable value in resisting tides, protecting coasts, purifying sea water environment, promoting ecological balance, and improving the living standards of coastal people. [0003] Mangrove is an ecosystem with unique structure and function, and the restoration and reconstruction of mangrove ecosystem is an important way to improve the biodiversity of coastal ecosystem. In addition to the functions of berm protection, wave dissipation,...
