摘　　要： 岩溶动力系统是一个边界受制于已有地表地下岩溶形态,与地球四圈层有密切联系的开放系统。该系统在生物圈的主导作用下与水圈、大气圈及岩石圈(土圈)相互作用,产生物质循环和能量流动,发生水-岩-气作用,进而在全球碳循环中发挥积极作用。生命物质在水-岩-气过程中的作用机制,尤其碳酸酐酶快速催化水和二氧化碳反应过程,以及多肽类生物大分子提高方解石中镁含量能力的发现,使岩溶动力学理论得到进一步丰富和发展。因此,如何更好的将现代生命科学理论引入到岩溶动力学中,丰富和发展岩溶动力系统模型,并与生产实践相结合,是联合国教科文组织岩溶研究中心落户桂林之后岩溶动力学理论发展过程中面临的新课题。 The karst dynamic system,closely associated with the earth＇s four spheres,is an open system with its boundary being constrained by the existed karst morphs under and on the ground.This system interacts with hydrosphere and atmosphere as well as lithosphere under the dominance of the biosphere to cause cycle of matter and flow of energy and interactions among water and rock as well as air,which playing an active role to the global carbon cycle.Karst dynamics is developed with the following discovery：the living-matter acting mechanics in the interaction among water and rock as well as air,especially the reaction of water with CO2 under the fast catalysis by carbonic anhydrase,and the improvement to the capacity of Mg content in calcite by polypeptide large biological molecule.Therefore,after the International Research Center on Karst under the Auspices of UNESCO settled in Guilin,it is a new task in karst dynamics theory as how to bring the modern life science theory into karst dynamics,to enrich karst dynamic system model and to combine the theory with production practice.
