Embodiment Construction

[0017] The present invention will be further described below in combination with specific embodiments.

[0018] A method for constructing a coastal reed wetland reed-crab-fish breeding compound system, the steps and conditions are as follows:

[0019] 1. The natural environmental conditions and supporting projects for the construction of the coastal reed wetland reed-crab-fish breeding composite system, the environmental conditions of the coastal reed wetland reed-crab-fish breeding composite system, and the arrangement of more and deeper open channels, etc. Engineering technology restores the hydraulic connection between the wetland and the river. The reed field is closed by ring ditches and dams, and has independent inlet and drainage gates to ensure smooth drainage of the reed field, and the normal growth of fish and crabs will not be affected during the drainage period;

[0020] 2. Construct a wetland area of ​​25-40hm 2 It is a unit field grid, and each grid has a ring d...

Abstract

Disclosed is a construction method for a wetland phragmites australis-eriocheir sinensis-fish plants and aquacultures coupling agriculture system of seaside phragmites australis. The construction method includes the steps and conditions of phragmites australis field infrastructural construction, phragmites australis population nurturing, three-dimensional eriocheir sinensis-fish mixed culture, capturing and temporary rearing and management and maintenance of the wetland system. The construction method has the advantages that the wetland phragmites australis-eriocheir sinensis-fish plants and aquacultures coupling agriculture system of the seaside phragmites australis is constructed, ecosystem functions of degraded vegetations and wetland conservation are restored, and the blank of the field is filled up.

Description

technical field [0001] The invention belongs to the technical field of restoration and conservation of coastal wetlands, and in particular relates to a method for constructing a composite system of reed-crab-fish breeding in coastal reed wetlands. Background technique [0002] reed( Phragmites australis ) community is one of the main plant communities in estuary coastal wetlands in northern my country. It has high ecological and economic value and plays an important role in maintaining the stability of wetland ecosystem structure and function. Restricted by soluble salt and water in the soil, coastal wetlands It shows degradation characteristics such as the increase of annual saline vegetation, the increase of alkali spot bare land, the dwarfing of reed plants and the decrease of vegetation coverage. The restoration of wetland is to restore the degraded wetland ecosystem into a healthy functional ecosystem through human activities. , the vegetation restoration project in the ...
