Embodiment

[0116] This embodiment provides a method for restoring the ecological environment of a seawater pumped storage power station. The method for restoring the ecological environment of a seawater pumped storage power station includes the following steps:

[0117] (1) Preliminary screening:

[0118] 1) Species composition of plant communities: the data of all plant communities are counted according to the three levels of trees, shrubs and herbs, and the important value (IV) of each species in each plot is calculated, and the species diversity index of the community is calculated .

[0119] 2) Soil site conditions: Use online satellite maps to search coastal sandy forest vegetation along the coastline of Guangdong. For the mangroves and sand shelterbelts that are both located in the coastal area, the following criteria are used to distinguish them: mangroves are generally directly connected to water bodies, and most of the land margins of the forest land are of the type of breeding...

Abstract

The invention provides a method for restoring the ecological environment of a seawater pumped storage power station, which is characterized by comprising the following steps: (1) preliminary screening: investigating vegetation of a coastal island and/or a sand bank protection forest sample plot, and then performing preliminary screening according to an investigation result, wherein the preliminarily screened salt-tolerant plants need to comprise arbor plants, shrub plants and herbaceous plants; (2) secondary screening: planting all salt-tolerant plants obtained through preliminary screening, carrying out a salt mist stress test, and carrying out secondary screening to obtain arbor plants, shrub plants and herbaceous plants which finally need to be planted; and (3) planting: carrying out mixed and graded planting on the screened arbor plants, shrub plants and herbaceous plants to realize the restoration of the ecological environment of the seawater pumped storage power station.

Description

technical field [0001] The invention relates to the technical field of ecological restoration engineering, in particular to a method for restoring the ecological environment of a seawater pumped storage power station. Background technique [0002] The seawater pumped storage power station is an effective supplement to the traditional pumped storage power station. The sea is used as a water storage reservoir, which saves costs, facilitates site selection, and overcomes the dependence on fresh water. application prospects. However, the construction and operation risks of the seawater pumped storage power station construction project mainly come from the splashing and leakage of extracted seawater under extreme weather conditions during the operation of the power station. However, coastal seawater spraying will bring significant plant salinity and soil salt accumulation, causing changes in plant morphology and an increase in soil salinity. From Liaodong Bay to the coastal are...
