侵蚀力侵蚀力 引起地表物质发生侵蚀的各种地貌外营力潜在能力的量度。地貌外营力包括 重力、水力、风力、溶蚀、冰川、冻融、 潮汐、海流、波浪、生物作用和人类活动等。某一地质外营力的侵蚀力大小， 主要取决于它作功所消耗能量的来源及其自然属性。如降雨侵蚀力是降雨引起侵蚀的潜在能力，是降雨物理特性的函数；风的侵蚀力完全受风速控制；重力作用强弱与坡度和有效地形高差关系密切；冻融作用强弱与土（岩）体含水量有关。侵蚀力能量主要来自宇宙能，同时也受地势高差影响。在美国通用土壤流失方程中，它可经验性地表征为降雨动能与最大30分钟雨强的乘积。流水侵蚀力来自水流所具有的动能，是流量与流速的函数。当片状水流特征流速为0.01米/秒时，动能约为降雨雨滴的1/100万，有3％左右成为侵蚀力。细沟流水特征速度为10米/秒，动能为雨滴的60％，约有3％成为侵蚀力，相当于雨滴侵蚀力的10倍，片状水流的百万倍。决定风的侵蚀力的重要因素是风的频度和风速。对于任何环境中出现的侵蚀，都受侵蚀力和地表物质抗蚀力两方面的作用，故一般认为侵蚀是侵蚀力与抗蚀力的函数，是其相互作用的表现。
