Other Abstract

Dominant native grasses were assembled for constructing communities in different slope runoff monitoring sites,and their effects and efficiencies on water and soil loss were examined under Yuanmou dry-hot valley conditions.The observation results from 2013 to 2015 showed that runoff generations and soil erosion modulus were positively correlated with rainfall(p<0.05);soil and water losses were significantly different between constructed native grasses community sites and CK sites,runoff generations and soil erosion modulus increased with the rise of slope gradients across all communities and CK sites;in contract,water utilization efficiencies of constructed native grass communities reduced with the increase of site slope gradients,and rose with increase of community coverage.The above results suggested that planted native grass communities significantly reduced water and soil loss and improved the reutilization of rainfall,and the reduction of soil and water loss was more obvious with the increase of slope gradient,which reveled that it could be more efficient when those communities were built in steep sloping lands in hilly.
