Research progress of hydrological cycle in karst critical zone
摘要
Karst critical zone is in the five circles intersection area of rock,water,soil,atmosphere and biology. Correct understanding of the structure,function and hydrological cycle process of the karst critical zone is a key problem in the study of the earth critical zone and karst water sciences. This paper analyzes the hydrological cycle process and evolution law in karst critical zone,the effect of hydrological cycle in karst critical zone,explores the rule and driving mechanism of water cycle evolution in karst critical zone under changing environment,summarizes the shortcomings,problems,and proposes the general trend and direction of future research:Interaction mechanism of formation and evolution of karst critical zone and hydrological cycle process;The process of material transformation and energy migration driven by hydrological cycle in karst critical zone and its coupling;Response of hydrological cycle process to global change and human activities at different spatial and temporal scales;Comprehensive application of multiple observation and simulation methods.
