摘　　要：钙华不仅具有重要的景观旅游价值,而且对确定区内碳酸盐沉积特征、环境演化规律及同期环境生物的作用与贡献有重要的研究意义。本文在对比国内外典型钙华特征的基础上,以黄龙和九寨沟为例,对雪宝顶区块流域内钙华的沉积特征、环境化学与生物作用进行阐述,指出了雪宝顶区块流域冷水型钙华的形成与演化是化学沉积-溶解作用、生物沉积与溶蚀作用等共同作用的结果,并受非生物、生物因素影响。在雪宝顶冷水型钙华的形成过程中,微生物协同参与了钙华的沉积与溶蚀过程,通过自身新陈代谢促活动促使使钙离子结晶,并诱导晶型变化;其他生物体如植物、藻类等或以间接的方式促进或加快了钙华形成,或为钙华生长提供模板和体量。Travertine not only has significantly ornamental value of landscape,but also has important research significance to determine the sedimentation law and environmental evolution of travertine and the role and contribution of environmental organisms in the same period.Based on the comparison of characteristics of typical travertine at home and abroad,this paper takes travertine in Huanglong and Jiuzhaigou region as examples to illustrate the sedimentation characteristics,environmental chemistry and biological effects of travertine in Xuebaoding drainage basin,and points out that the formation and evolution of cold water type travertine in Xuebaoding drainage basin are the results of the conbined effects of chemical sedimentation-dissolution,biogeochemistry,biogenic sedimentation-dissolution,which are affected by non-biological and biological factors.In the formation process of cold-water travertine in Xuebaoding drainage basin,microorganisms participate in the sedimentation and dissolution process of travertine,promote the crystallization of calcium ions by metabolism,and induce the change of crystal form.Other organisms such as plants and algae either promote or accelerate the formation of travertine in an indirect way,or provide a template and volume for the growth of travertine.
