The relationship is a complex combination of the type of soil, the rainfall regime, the plant species present, the slope aspect, and the steepness of the slope. Knowledge of the underlying slope stability as a function of the soil type, its age, horizon development, compaction, and other impacts is a major underlying aspect of understanding how vegetation can alter the stability of the slope.〔Mattia, C.; Bishetti, G. & Gentile, F. 2005, ‘Biotechnical characteristics of root systems of typical Mediterranean species’, Plant and Soil, vol. 278, no.1, pp. 23-32〕 There are four major ways in which vegetation influences slope stability: wind throwing, the removal of water, mass of vegetation (surcharge), and mechanical reinforcement of roots. ==Wind throwing== Wind throw is the toppling of a tree due to the force of the wind, this exposes the root plate and adjacent soil beneath the tree and influences slope stability. Wind throw is factor when considering one tree on a slope, however it is of lesser importance when considering general slope stability for a body of trees as the wind forces involved represent a smaller percentage of the potential disturbing forces and the trees which are in the centre of the group will be sheltered by those on the outside.〔Greenwood, J.; Norris, J. & Wint, J. 2004, ‘Assessing the contribution of vegetation to slope stability’, Proceedings of the Institution of Civil Engineers, vol. 157, no. 4, pp. 199-207.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Vegetation and slope stability」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
