Problems solved by technology

After plants are eroded, the salt content of the soil increases, causing soil damage. If you want to continue planting plants, you must first repair the eroded soil. There are also many methods for repairing coastal wetlands on the market, but many of them are not environmentally friendly. , as well as livestock manure, can be used, which will be more environmentally friendly and reduce costs

Embodiment 1

[0029] A method for restoring damaged vegetation in coastal wetlands, comprising the steps of:

[0030] S1. Determine the restoration area and conduct habitat survey: conduct a comprehensive understanding of the state of the target wetland before damage, the cause of damage, and the degree of human interference during the restoration process, so as to select the area that needs ecological restoration; the second is to carry out Habitat survey, including a comprehensive survey of the climatic conditions, soil conditions, water resources, vegetation, animal and plant resources of the target wetland;

[0031] S2. Water pumping transformation: determine the area that needs to be restored ecologically, set a cut-off baffle around the area, use a pump to pump out the water in the area, and move along the two sides of the water flow direction in the area Slope reconstruction forms multiple steps of different heights to form multi-level wetland ecosystem units. Living wetland vegetati...

Abstract

The invention relates to the technical field of restoration of coastal wetlands, in particular to a restoration method of damaged plants in a coastal wetland. The restoration method comprises the following steps of S1, determination of a restoration area and habitat survey; S2, reshaping by pumping water; S3, shaping by water discharge; S4, soil ploughing in the restoration area; S5, soil laying;S6, plant cultivation. An underwater ecosystem is constructed, and the absorption, adsorption, sedimentation promotion and physiological metabolism activities of primary oxygen produced by photosynthesis of submerged vegetations and underwater forests achieve the purposes of effectively removing nitrogen, phosphorus and other nutrient pollutants in water and increasing dissolved oxygen in the water to purify the water; crop straw is used as a natural fertilizer, which not only avoids the situation that rural straw burning pollutes the environment, but also increases organic matter and nutritional ingredients in damaged soil, and is more environmentally friendly and also makes the cost low; the crop straw is buried in the damaged soil for fermentation rot, so that the soil is looser and softer, and the saltness per unit area is reduced, thereby being more conductive to planting.

Description

technical field [0001] The invention relates to the technical field of coastal wetland restoration, in particular to a method for restoring damaged vegetation in coastal wetlands. Background technique [0002] As the ecotone of the two systems of sea and land, coastal wetlands have powerful ecological service functions, including water conservation, water supply slowdown, erosion control, back-up land resources, nutrient salt and pollutant decomposition, and habitat for aquatic and marsh organisms. land, breeding area and migratory bird migration and overwintering grounds, etc. In recent years, due to the intensification of human activities in the upper reaches of the river and coastal areas, the sediment content in the estuary area has changed, which directly affects the erosion and deposition environment in the estuary area, resulting in the reduction of the area of ​​the estuary wetland and the degradation of its function. At the same time, with the implementation of nea...
