摘　　要：中国科学院普定喀斯特生态系统观测研究站长期致力于我国西南喀斯特表生过程研究,研究成果揭示了贵州高原喀斯特生态系统物质循环规律及驱动力,论证了我国西南喀斯特碳、氮等营养元素和水循环过程与全球变化响应、反馈机制;剖析了喀斯特生态系统结构与功能、格局与过程,实现对石漠化发生、演变动力学机制的深刻解析,探明了喀斯特退化生态系统修复的途径和机理,并进行示范;针对喀斯特不同地质地貌类型区特点,构建了石漠化治理与生态恢复模式,为西南石漠化地区的生态恢复提供了基础理论和技术支撑。The Puding Karst Ecosystem Research Station has been committed to researching karst surface systematic processes in Southwest China.Its research endeavors have revealed material circulation and driving forces in the ecosystems of the Karst plateau and demonstrated carbon cycling process response and feedback mechanism to global change.The present research explores the structures,functions,patterns,and processes of karst ecosystems,analyzes the dynamic mechanism of karst rocky desertification,and provides the basic theory and technical support for the restoration of degraded karst ecosystems.According to the characteristics of different geological karst regions,different types of approach were established for the control of karst rocky desertification and ecological restoration,which provided the basic theory and technical support for the ecological restoration of rocky desertification in Southwest China.
