桂西北喀斯特生态系统退化机制与适应性修复试验示范研究

围绕喀斯特退化生态系统恢复与重建的国家重大需求,针对喀斯特生态系统植被群落稳定性差、土壤生态功能恢复滞后、生态治理成效缺乏可持续性等问题,依托广西环江喀斯特生态系统国家野外科学观测研究站,我们开展了桂西北喀斯特生态系统退化机制及适应性修复研究,提出了喀斯特生态系统服务功能优化调控的理论与技术体系,为西南喀斯特区域石漠化综合治理及社会经济可持续发展提供科学依据与技术支撑。

Experiment and Demonstration on Degraded Mechanism and Its Adaptive Restoration of Karst Ecosystems in Northwest Guangxi

To meet the needs of restoring and reconstruction of degraded karst ecosystems, this research was aimed to develop ecological protection and restoration technologies for the improvement of low stability of vegetation community, lag behind of soil functionality recovery, and lack of sustainability of ecological restoration and reconstruction. We firstly explored the land degraded mechanism and adaptive restoring technologies for degraded karst areas in Northwest Guangxi based on Huanjiang Observation and Research Station for Karst Ecosystems, Chinese Academy of Sciences. Then, we proposed and established a comprehensive theoretical and technological system for the optimization and management of karst ecosystem functionality. This research could provide scientific and technological foundation for the comprehensive controls of karst rocky desertification and sustainable development of social economy in karst areas, Southwest China.
