The results show that due to the destruction of forest vegetation, the steep slope reclamation and water channel leakage in the Taojia small river basin, well fields and forest land at multiple sites in the basin have been buried by mud and rock, and abundant forest vegetation distributed in the middle and upper reaches has reduced to the situation of a forest coverage rate of only 15.5%. As a result, a vicious circle of "ecological destruction, soil erosion, farmland reduction, poverty, steep slope cultivation, ecological destruction" has been formed. Based on the analysis of the basic ecological background of the basin, six ecological restoration proposals such as planting soil and water conservation forests and fruit trees and blockading protection were proposed, in order to provide support for restoring the ecological environment of the basin and achieving sustainable development of the ecological environment within the basin.展开更多
