Project 661 - The Critical Zone in Karst Systems

Brief outline of the project

In the past 25 years, the international cooperation based on the IGCP projects in karst field attracted more than 200 scientists from over 40 countries to participate in. Based on the research team for international cooperation and the understanding of connotation of critical zone, we put forward the new IGCP project themed on "Global comparative research on structure, substance cycle and environment sustainability of the critical zone in karst systems". The new IGCP project will mainly pay attention to some scientific issues such as the structure, evolution, cycle of carbon-water-calcium and function of the critical zone and its sustainable utilization of the resources and environments.

It will focus on several aspects, which are influence of Himalaya uplift, highland in Middle East Area and the orogeny of Alps to the formation and evolution of karst; Influence of geological structure and differentiation of climate and vegetation on types, hydrogeological structure and characteristic of the critical zone; Influence of biogeochemical process, especially the microorganism action on substance cycle of the critical zone; The hydro-ecological and carbon sink function, influence factors, recording index, and maintaining mechanism of the critical zone; And establishment of monitoring stations and standards in different critical zones of the world.
