Analysis of Soil Fertility in the Preliminary Stage of Ecological Slope Protection in Guandi Hydropower Station

Article Preview

Abstract:

The soil fertility was measured in four experimental plots on human-induced restoration slopes like vegetation-growing concrete spraying bio-slope (CBS) and external-soil spray seeding bio-slope ( ESS) in Yalong River Guandi Hydropower. The results showed that the soil fertility level of four repaired slopes were significantly higher than the control sample, and there was no significant difference among these experimental slopes except for the slope D (right bank CBS) which was the highest in all of slopes. It indicated that the technology of ecological slope protection can improve soil quality in the disturbed areas of Guandi Hydropower Station, Yalong River. The results of using vegetation-growing concrete base material spraying technology were better than the external-soil spray seeding technology.
