Outline
The practice of ecological governance and reforestation was carried out by taking Pianyanzi fluctuation zone as the object, proposed the stone cage anti wall technology, stone cage plate slope protection technology, ecological bag slope protection technology, which provides the necessary soil matrix for plant growth and prevents the soil from being soaked by reservoir water and erosion. On this basis, more than a dozen species of water-resistant plants were screened, and different plant species were configured in different elevation areas. After a long period of inundation in one hydrological year, the overall survival rate of trees and shrubs was 54.9% and 35%, respectively. Among them, Taxodium ascendens Brongn, Ascendens mucronatum, Betula nigra, Myricaria laxiflora, and Salix variegata had better submergence tolerance and higher survival rates, which were 84%, 74.2%, 88.3%, 97%, and 95%. They could withstand long-term overtop submergence, and the effect of reforestation in the water-level zone was obvious.
