Abstract

Huanjiang Observation and Research Station for Karst Ecosystems (HORSKE) of Chinese Academy of Sciences was founded in 2001. Since then HORSKE has been committing itself to serve the national needs for rocky desertification restoration, ecosystem services promotion, and human wellbeing improvement. HORSKE has carried on comprehensive and long-term monitoring, experiment, and demonstration to the degraded karst ecosystem. HORSKE found the dual loss characteristics for both soil and water, revealed that surface soil erosion modulus on karst hillslopes is less than 50 t/(km 2·a) and human disturbances could intensify the surface soil erosion speed. Furthermore, HORSKE clarified the effects of human activities on the degraded karst ecosystem and its mechanisms and expounded the interaction mechanisms of landscape pattern and key ecological processes in karst areas. HORSKE also developed adaptive restoration technology for degraded karst ecosystem. At the regional scale, HORSKE evaluated the ecosystem services changes under the implementation of ecological conservation projects. In addition, HORSKE proposed effective measures for karst landscape protection. For regional poverty alleviation, HORSKE developed and proposed scientific and technological modes for poverty alleviation in the karst eco-fragile areas. During the past 20 years, HORSKE has established theories and technologies for karst ecosystem services optimization and management. Long-term ecological research and demonstration in HORSKE has made important progresses on karst eco-environmental management and poverty alleviation. HORSKE supports scientific foundations for combating rocky desertification and regional poverty alleviation in the karst region of Southwest China.
