| 摘 要： | 我国滨海岩溶地区岩溶系统的形成具有其独特的动力学过程。其中，既有自然环境条件下形成的岩溶特征，又有人类活动的地质效应——海咸水入侵的影响和改造。目前，海咸水入侵对滨海岩溶系统的影响和改造正在加剧，并将逐渐成为主导因素。防治滨海岩溶区海咸水入侵的根本，就是要查明咸-淡水过渡带中碳酸盐岩溶解、沉淀的动力机制。其中，混合溶蚀作用是关键。开展咸-淡水过渡带碳酸盐岩溶解、沉淀动力学的野外现场定位观测和室内动态模拟实验研究，并在查明咸-淡水过渡带碳酸盐岩溶解、沉淀动力机理的基础上，建立滨海岩溶地区碳酸盐岩溶解、沉淀系统动力学模型是十分必要和迫切的。研究各种因素综合影响下，滨海碳酸盐岩的混合溶蚀作用，将有利于查明滨海岩溶形成机理，进而为解决滨海岩溶地区海咸水入侵问题开辟一条新的途径。

| Abstract: | There is an unique dynamics process of karst forming in littoral karst systems in China. There are not only karst features under the natural conditions but also geological affection of human activity, that is influence and changes of sea salt water intrusion. At present, the sea salt water's influence and changes to littoral karst system are gradually intensified and they are becoming the main factor day after day. To prevent and cure sea salt water intrusion in littoral karst area, it's essential to find out the dynamical mechanism of carbonate rock's dissolution and sedimentation in salt fresh water mixed zone. Among these, the mixed corrosion is the key point. It is very important and urgent to build the dynamical model of carbonate rock dissolution and sedimentation on the basis of field observation on site and experimental study of carbonate rock dissolvent and sedimentation in mixed zone of seawater and freshwater. The studying of littoral carbonate rock's mixed corrosion synthetically influenced by various factors will conduce to find out the form mechanism of littoral karst. Moreover, it will break a new path to solve the sea salt water intrusion in littoral karst area. |
