钙华体次生有机体系的界面结晶作用研究

本文总结了钙华体次生有机体系中生物群落特征和界面结晶行为，根据生物在碳酸盐沉积中的角色，将钙华体中次生有机体系的界面结晶矿化类型分为生物控制矿化沉积和生物诱导矿化沉积。分述了碳酸钙沉积矿化相关的五种生物代谢活动，讨论了生物胞外聚合物（EPS）对碳酸钙矿物晶型和形貌的影响。针对目前钙华研究中存在的问题，今后应深入研究生物体主要构成元素、生物小分子和生物体内部组织在钙华形成或退化中的作用，进一步厘清钙华体与次生有机体系的多界面溶化方式，为钙华保护修复及钙华退化治理措施提供科学依据。 

Research progress on interfacial crystallization of travertine in secondary organic system

The characteristics of biomes and interfacial crystallization by organisms in secondary organic system are summarized in this papar. According to the effects of organisms on carbonate sedimentation， the interfacial crystallization mineralization of travertine by organism in secondary organic system is divided into bio-controlled mineralization and bio-induced mineralization. Five biometabolic activities related to sedimentation of calcium carbonate are described， and the effects of EPS on the crystal type and morphology of calcium carbonate minerals are discussed. In view of existing problems in the researches on travertine， it is suggested that the role of main components of organisms， biomolecules and internal tissues of organisms in the formation or degradation of travertine shall be studied in depth， and the interfacial crystallization of travertine in secondary organic system can be further clarified， so as to provide scientific basis for the protection and treatment measures to prevent travertine from degeneration.
