岩溶关键带水循环过程研究进展

Research progress of hydrological cycle in karst critical zone

岩溶关键带处于岩石、水、土壤、大气、生物五圈交汇地带。正确认识岩溶关键带的结构、功能及其水文循环过程是当前地球关键带与岩溶水科学研究的关键问题。剖析了岩溶关键带水循环过程与演变规律、水循环过程在岩溶关键带中的作用,探寻变化环境下岩溶关键带水循环过程演变的规律与驱动机制,总结不足与问题,提出未来研究的总体趋势和方向:岩溶关键带形成与演化和水循环过程相互作用机制;岩溶关键带水循环驱动的物质转化与能量迁移过程及其耦合;水循环过程在不同时空尺度上对全球变化与人类活动干扰的响应;多种观测与模拟手段的综合应用。

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.
