1、绪论 地名为代表某一地形或地城之符号,其决定与变更类受当时人为因素及常地自然因素之影响或控制。故地名之研究具有历史上及地理上之意义。今日之地名常以古代国名或古代史实构成其一部。甚至古代民族迁徒之迹亦可於地名中见之,且其正确与精密往往在历史文字纪拔之上,而以欧西各地为尤然。故法人白吕纳(Jean Brunges)谓地名可视篇古物之一种,其性质与化石、奖章、钱币无异。地名之有历史性,至为显然。地名

一、引言 浸蚀史之研究为现代地形学之中心问题,其研究之旨趣在探讨基面变化循环更新所产生之影响,与所经过之演变。本文以为江南岸支流——猫跳河为例,研究其纵街剖面之变化,以推论贵州高原中部之侵蚀历史,尤着重纵剖面之分析与讨论。 裂点之保存与否,以岩石品质及水量大小而定。一般而论,主流之裂点声以水量较大,破坏较速,远无支流上裂点保存
雷州半岛舆山东半岛恰成一有趣之对比。在华北大平原之坦岸中,山东半岛呈一例外现象,多良港;而雷州半岛则在华南山岭区之崖岸中,反呈低平外貌,海港无一优良者!前者久经中外学者之探讨,而後者则寂寂无闻,其实雷州半岛之地形,尤富研究之兴趣。该区地壳最近之运动,火山之爆发,岩浆之外溢,毕露於地形上,稍俱地形之学识者,即未尝步履其地,亦可一一加以确定也。

本文所及之岷江峡谷,谨其由灌县城至汶川县映秀湾之一段,适当康藏大地块与四川盆地之接触地带,区内主要大道有三,一循岷江北岸经龙溪越娘子岭至映秀湾以通岷江上游,二循岷江南岸径漩口至映秀湾与前道合为通岷江上游之偏道,三沿岷江南岸经漩口转循支流寿河而上以通懋功,除第一道较宽坦可通骡马外,其余二道均为小道,谨供人行。
