晚新生代贵州高原喀斯特地貌演进及其影响因素

摘要

In this paper, three determined factors influencing on the evolution of karst geomorphology of upper Cenozoic in Guizhou, e.g. geological basis, neotectonic movement and neoid climate fluctuation are discussed. Landscapes of karst morphologies consist of three main bodies which are peak forests, peak clusters and hill－peak clusters in Guizhou plateau, their development and distribution are mostly dominated by stratum, lithologic character and folding form；Highly increase in the neotectonic heights causes remarkable differentiation to intensity and manner of karst action of plateau and gorge two geomorphological systems. Besides, particular landscapes of hydrographic morphology that formed are due to neoid active of fault (or fold). Fluctuation of warm and cold climate produces an environment of external forces of alternative karst action of strong to decline. Wholly, It is advantageous to maintain surface of karst plateau in Guizhou.%本文对晚新生代贵州喀斯特地貌演进的三大控制因素，即地质基础、新构造运动及挽近气候波动进行了分析论证。贵州高原以峰林、峰丛、丘丛—峰丛为主体的三大喀斯特地貌景观，其发育分布主要受地层岩性及褶皱型式的控制；新构造大幅度抬升使高原与峡谷两大地貌系统喀斯特作用的强度及方式发生显著分化，而断裂(褶皱)的挽近活动则导致特殊水文地貌景观的形成；气候冷暖波动造成喀斯特作用强弱交替的外力环境，总体上有利于贵州喀斯特高原面保存。
