Coastal constructed wetland used for water bird conservation and construction method thereof

Abstract

The invention discloses a coastal constructed wetland used for water bird conservation. The coastal constructed wetland comprises a pond unit, planting units, partitioning units and water level control units; wherein the pond unit is filled with pond water, the planting units are arranged on the periphery of the pond unit and partitioned through the partitioning units, and the water level control units are arranged in the planting units and used for adjusting water levels in the plating units. According to habitat characteristics of coastal paddy fields and requirements for the habitat of water birds, a foraging place and a concealing and inhabiting place of the water birds are constructed based on the paddy fields, so that the effect on water bird conservation of the coastal paddy fields is effectively promoted, and the quality of the inhabiting place for the water birds is improved. The invention further discloses a construction method for the coastal constructed wetland used for water bird conservation.

Description

technical field [0001] The invention relates to the technical field of waterfowl conservation in coastal rice fields, in particular to a coastal artificial wetland for waterfowl conservation and a construction method thereof. Background technique [0002] Coastal wetlands are natural complexes between terrestrial and marine ecosystems. They are one of the wetland ecosystems with the highest productivity and the richest biodiversity on earth, and play an important role in the balance and stability of the global ecosystem. Coastal wetlands provide a large amount of food and good habitat for waterfowl, and play a pivotal role in the migration, wintering and reproduction of waterfowl. [0003] In recent years, affected by global climate change and human production activities, a large number of coastal wetlands have gradually degraded or even disappeared. Excessive reclamation has caused some coastal wetlands to be replaced by farmland, especially rice fields, forming a large are...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the defects in the prior art that coastal wetlands are replaced by paddy fields, the planting density of paddy fields is too large, the water level is too low, and there is no open water area and hidden environment, which adversely affects the habitat of waterfowl, the present invention proposes a Coastal Constructed Wetland and Construction Method for Waterfowl Conservation
