Embodiment 1

[0023] In this example, Zhanjiang Techeng Island beach and Zhanjiang Bay beach base are selected as the experimental sites, and the restoration of the mangrove wetland ecosystem is carried out according to the following steps:

[0024] 1) Observing and investigating the hydrodynamics, geology, coastal sediments, geomorphology and mangrove growth factors of Techeng Island and Zhanjiang Bay mangrove sea area;

[0025] 2) Coupling modeling with relevant fluid analysis software and solid analysis software, and performing simulation and analysis based on the data in the first step, involving an optimization plan for mangrove planting;

[0026] 3) According to the optimization plan in the second step, guide the artificial planting of 1,000 mangroves in the small and medium-sized areas of Techeng Island and Zhanjiang Bay, track the survival and growth of mangroves, and observe the status of the coastal wetland ecosystem .

[0027] According to the results of field investigation and ...

Abstract

The invention discloses an offshore area wetland ecosystem remediation method. The method comprises the following steps that S1, a specific offshore area wetland is selected, and hydrodynamic force, geologies, coast deposition, landform and mangrove forest growth elements of the wetland are observed and investigated; S2, a simulation and analysis optimization design platform is established, the rule of parameters in step S1 and the relation between the parameters are analyzed, and an optimization scheme is designed; S3, a mangrove forest is planted in the selected offshore area wetland according to the optimization scheme in step S2, the survival and growth conditions of the mangrove forest are tracked, and the condition of the ecosystem of the offshore area wetland is observed. By means of the method, the survival rate of the mangrove forest in the offshore area is improved, the ecological state of the offshore area wetland is improved, especially coastal dynamics, sediment transportation and deposition are improved, the purpose of restoring the ecosystem of the offshore area wetland is achieved, and the method has important application value for remediation and sustainable development of the ecosystem of the mangrove forest wetland.

Description

technical field [0001] The invention relates to the field of ecosystem restoration, and more specifically, to a method for restoring an ecosystem of a wetland in coastal waters. Background technique [0002] The most typical representative of coastal wetlands is mangrove wetlands. Mangrove Forests grow in tropical and subtropical regions, in coastal intertidal zones at the junction of land and ocean or in river estuaries where tides can reach, and are affected by periodic tides. flooded. The tidal flat wetland woody biome composed of evergreen shrubs or trees dominated by mangroves is known as "submarine forest" and "water oasis", and is an international key natural protection object. As an important type of coastal wetland, mangrove wetland has been included in the Ramsar Wetland Classification System and the Coastal Wetland Classification System formulated by the Fourth Ramsar Convention Member Conference. Research by ecologists has recognized the important role of mangr...
