摘要:

运用岩溶地貌及洞穴次生化学沉积物的成景机制和原理,结合动态耦合的方法和系统的观点,通过“洞穴”这一共同作用的对象,将洞穴的区域地质背景、洞穴外部环境、洞穴内部环境与洞穴次生化学沉积物成景过程进行有机联系,创立某一洞穴次生化学沉积物成景耦合系统,概括其内涵、特征和意义。同时通过对广西巴马水晶宫区域地质背景、洞穴外部环境、洞穴内部环境等系统分析和研究,全面系统探讨水晶宫洞穴次生化学沉积物的成景耦合过程,并按不同时期区域构造运动的程度及洞穴次生化学沉积物的形成特征,将该成景耦合过程划分为4个可往复循环的阶段:① 区域构造平稳前期—洞穴次生化学沉积物形成发育阶段;② 区域构造平稳中期—洞穴次生化学沉积物大规模发育阶段;③ 区域构造平稳后期—洞穴次生化学沉积物缓慢或停止发育阶段;④ 区域间歇性构造运动—洞穴次生化学沉积物崩塌阶段。

Abstract:

Based on landscape formation mechanism and its principles for karst landform and speleothems, "cave"--the jointly processing object -- has been studied through dynamical coupling methods and system. A cave has been studied by correlating its regional geological background, internal and external environment with speleothems formation organically. A coupling system for speleothems formation has been thus created, which has generalized the content, characteristics and significance. At the same time, it has examined the regional geological background of Shuijing Cave in Bama of Guangxi, the external environment (climatic features and evolution, CO2 source and conversion of karst water, evolution of recharge and development of karst water, vegetation, soil types and soil covering features, etc.) and internal environment (infiltration patterns and amount of karst water from cave wall, cave atmosphere, CO2 content, temperature and humidity, etc.) systematically. Besides, it has also analyzed the coupling process of speleothems formation in Shuijing Cave comprehensively. According to different regional tectonic movement extents and speleothems’ features in different geological periods, the coupling process of the speleothems formation could be identified into 4 recyclable periods: (1) early stable period of regional tectonic movement -- the speleothems were formed and developed; (2) middle stable period of regional tectonic movement -- the speleothems were developed in large scale; (3) late stable period of regional tectonic movement -- the speleothems were developed slowly or even ceased growing; (4) intermittent regional tectonic movement -- the speleothems began to collapse.
