| 摘 要： | 通过分析大量相关文献并结合作者近年来的工作成果,总结了四种钙华沉积模式: 泉水、河流障、湖泊以及沼泽钙华沉积;综合讨论了气候环境、水文地质条件、水体的物理化学性质、生物作用等因素对钙华沉积的影响。针对目前研究中存在的问题,作者认为今后的工作要从碳酸钙沉积反应的热力学、动力学和晶体生长等微观过程进行研究,从而更加全面地认识钙华沉积的机制,以便为钙华景观的科学保护提供理论基础。

| Abstract: | Four kinds of travertine precipitation models,i.e.spring,river impediment,lake and marsh travertine precipitation,are summarized through analysis on a number of research works in recent years,and the role of climate,hydrogeological conditions,physical and chemical properties of the water,organisms and other factors played in the travertine precipitation are discussed comprehensively in this paper.In the sight of the existed problems at present,the authors think the research work in the future should be carried out and focus on micro-process of CaCO_3 precipitation reaction such as the reaction's thermodynamics,kinetics and crystal growth so as to comprehend travertine precipitation mechanism more completely and provide theoretical basis for the protection of tufa / travertine landscape. |
