Prevention and Control Measures for Soil Erosion in Reservoir Project
Due to the disturbance of the original surface in reservoir construction,the original surface soil is destroyed and vegetation is deteriorated,resulting in greater bare soil surface area,and part of the soil and water conservation facilities are damaged,weakening the erosion resistance of the soil.Moreover,the engineering behaviors such as topsoil stripping and dump,dam foundation cleaning,foundation pit excavation and backfilling,temporary dump of earth for backfill,reservoir cleaning,and dregs storage,etc.have seriously aggravated the soil erosion,and the amount of soil erosion in the area increased sharply.This paper describes in detail the topsoil stripping,topsoil recovering,rehabilitation of cultivated land in soil erosion control area including the construction area,reservoir inundation area,traffic road area,earth yard area,and resettlement area,as well as the soil erosion control measures such as drainage,slope protection,and greening.
