Effect of Forests on Slope Stability and Global Enviroment

Abstract

Various problems on the global enviroment become the center of public interest in the world. These problems are complicatedly connected with the increase of CO₂, the destruction of ozonic layer, the dcrease of forests and the expansion of desert lands etc. This paper deals with a method to evaluate quantitatively the effect of forests on the hillside land slide, as one of the abovementioned problems. A new coefficient Cp to express the effect of tree roots on slope stability is proposed in this paper.
