Reconstruction method for large-scale offshore wetland of river or lake or sea

Abstract

The invention relates to a reconstruction method for a large-scale offshore wetland of a river or a lake or the sea. The reconstruction method comprises the following steps that the offshore wetland is subjected to spaced partitioning strip-block-shaped excavation, a formed land part is excavated into a channel communicating a water area, and a comb-shaped wetland form is formed; spaced artificial highlands are built in the offshore water area, and the length direction of the artificial highlands is consistent with the arrangement direction of the channel; animal raising and plant culturing are conducted on the land-based wetland, and a complete ecological system is built; after the land-based wetland evolves into a land and the channel evolves into a new land-based wetland, the land evolved by the land-based wetland is excavated, a new channel communicating with the water area of the river or the lake or the sea is formed, and then the comb-shaped wetland form is formed again; animal raising and plant culturing are conducted on the land-based wetland, and the complete ecological system is built; and the two steps mentioned above are repeated. By the adoption of the reconstruction method, the wetland is reconstructed with the low cost, the sustainable development ecological environment of the wetland is formed, and the reconstruction method is favorable to protection of habitats of aquatic resources and ecological restoration of eutrophic water bodies.

Description

technical field [0001] The invention belongs to the technical field of wetland transformation, in particular to a method for transforming large-scale rivers, lakes, seas and coastal wetlands. Background technique [0002] Most of China's lakes, rivers, and coastal areas are in the process of extensive reclamation and construction. The construction in the past few years has completely destroyed the wetlands in these waters. The destruction of these coastal habitats has brought about a serious ecological crisis. First, the shortage of resources Habitat loss, and the second is the large-scale destruction of wetlands that are free from ecological pollution. As a result, eutrophication and resource degradation of lakes and coastal waters are caused. Lakes are characterized by large-scale blooming of blue-green algae, and coastal waters have not only red tides, but also green tides. [0003] In the past, lake reclamation was for land reclamation, which improved the beach and turn...

Problems solved by technology

In the existing wetland construction and management, there are usually the following erroneous practices: For example, the wetland construction is completed, it is completely closed, and it is no longer maintained, resulting in swamping of the wetland and eventually evolving into land, and the wetland ecology is not sustainable For another example, failure to pay attention to the conservation of the organisms in the wetland area, the unreasonable allocation of organisms in the wetland area, resulting in the failure to form a stable biological community, thus failing to realize the value of wetland protection
