Embodiment Construction

[0031] The following examples are further detailed descriptions of the present invention.

[0032] A method for restoring plants in shell embankment wetlands in the Yellow River Delta, comprising the following steps:

[0033] Habitat survey method:

[0034]First of all, the applicant conducted a large number of surveys and investigations on the shell embankment wetland in the Yellow River Delta, and finally selected the Wangzi Island area, which has the most complete topography and landforms and well-developed vegetation, as the target for plant restoration in the shell embankment wetland. During the peak growing season (early August ~early September), conducted an in-depth investigation of the topography, elevation, soil environment, distance from the sea and land, human activity disturbance, and wave erosion of the shell embankment wetland in the Prince Island area by using the method of transect and quadrat investigation . The transects and quadrats are set as follows: a ...

Abstract

The invention discloses a wetland rejuvenation method for shell dikes of the yellow river delta by utilizing plants. The wetland rejuvenation method comprises following steps: adopting a survey method for belt transects and quadrats to measure an altitude in a selected wetland rejuvenation plot; record topographic and geomorphic conditions the sealand distance, sea wave erosion and human disturbance probability; collecting soil and measuring physicochemical properties of soil, and counting above features by utilization of a CCA order; dividing areas based on habitat conditions of selected wetland rejuvenation plots; screening adaptive plants and adaptive restoration species in all habitat areas; eliminating plants with importance value less than five and ordering remaining species in a CCA order; and selecting adaptive plants in all habitat areas and recovering plants by zoned plantation. The wetland rejuvenation method for shell dikes of the yellow river delta by utilizing plants has following beneficial effects: by following the principle of adjusting measures to local conditions, targeted investigations are made on wetland regions; the problem of vegetation degradation in shell dikes of the yellow river delta is effectively solved; and the wetland rejuvenation method is high in operability, low in cost and maintenance cost and obvious in landscaping and ecological functions and has great social benefit and environmental benefit.

Description

technical field [0001] The invention relates to the technical field of wetland plant restoration, in particular to a method for restoring shell embankment wetlands in the Yellow River Delta with plants. Background technique [0002] Coastal beach wetlands are the forefront ecological defense line of coastal wetlands. As a type of ecotone where water and land meet, its unique edge effect makes its structure and function complex, and its habitat is extremely harsh. It is vulnerable to wave erosion and seawater flooding. At the same time, it has the habitat characteristics of shallow groundwater table, frequent sea breeze and sand burial, high soil salinity, scarce fresh water resources and poor nutrients. It is one of the important ecosystems in the coastal zone. The shell embankment (chenier) coast of the Yellow River Delta on the southwestern coast of Bohai Bay in my country is one of the three remaining relatively well-protected shell embankment wetland ecosystem types in t...
