About: Cycle of erosion

An Entity of Type: person, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The geographic cycle, or cycle of erosion, is an idealized model that explains the development of relief in landscapes. The model starts with the erosion that follows uplift of land above a base level and ends, if conditions allow, in the formation of a peneplain. Landscapes that show evidence of more than one cycle of erosion are termed "polycyclical". The cycle of erosion and some of its associated concepts have, despite their popularity, been a subject of much criticism.

  • The geographic cycle, or cycle of erosion, is an idealized model that explains the development of relief in landscapes. The model starts with the erosion that follows uplift of land above a base level and ends, if conditions allow, in the formation of a peneplain. Landscapes that show evidence of more than one cycle of erosion are termed "polycyclical". The cycle of erosion and some of its associated concepts have, despite their popularity, been a subject of much criticism. (en)
  • 地形輪廻（ちけいりんね）とは、河川の侵食により地形が変化して行く過程のこと。侵食輪廻（しんしょくりんね）とも言う。アメリカのウィリアム・モーリス・ディヴィスが提唱した。 原地形（げんちけい）が侵食を受けて幼年期地形（ようねんきちけい）となり、壮年期地形（そうねんきちけい）、老年期地形（ろうねんきちけい）を経て平坦な準平原（じゅんへいげん）となる。 (ja)
  • 侵蚀轮回说也叫地理轮回说、地貌轮回说。是一种关于地貌演化过程的学说。1889年由美国地理学家威廉·莫里斯·戴维斯最先提出。这种理论认为地貌是构造、营力和时间（侵蚀阶段）的函数。例如，构造运动使地壳上升为山地，山地在流水不断侵蚀下，要经历以河流下蚀作用为主的幼年期，以侧蚀作用为主的壮年期和侵蚀微弱地面降低为缓坡的老年期，到最后地面被夷平为准平原。然后地壳再次上升，进入下一个轮回。这就是河流侵蚀轮回。此外根据营力不同还有风蚀轮回、冰蚀轮回和海蚀轮回等。每一轮回都可分为幼年、壮年、老年不同阶段，各演化阶段具有不同地貌特征。该理论曾经是地貌学的一项重要的基本理论，影响长达数年，对20世纪初期地貌学的发展有很大的推动作用。 (zh)
