Hunagjiang station, established in 1999, is one of the field stations of the Chinese Ecosystem Research Network (CERN) and a member of Global Terrestrial Observation System (GTOS). The station aims at developing the monitoring approaches for the mechanism (succession, degeneration and responses) of Karst ecosystems, the evaluation of ecosystem service functions and health, the development techniques of sustainable and optimized for Karst ecosystems, and is also a demonstration base for technologies of Rocky Desertification Treatment in Guangxi Zhuang Autonomous Region. In 2005, the station became one of the stations of the China National Ecosystem Observation and Research Network（CNERN）. Hunagjiang Station is located in Hunagjiang county of Guangxi Zhuang Autonomous Region(24°44' N, 108°19'E and elevation at 272.0～647.2 m), represents the Karst peak-cluster depression area in the southwest China. By the prominent contradiction between human and nature resources, human unreasonable land use caused serious soil and water loss, so bare rock desertification has become the main problem that threatens the sustainability of Karst ecosystems in this area. The researches conducted at the station focus on the long-term investigations of Karst ecosystem, ecological reconstruction of degradating peak-cluster depression ecosystem, exploring karst ecosystem succession process, and providing the demonstration(technology source, research platform) for the ecological reconstruction model.. The station has 146.1 ha land for field research and provides accommodation for scientists and students to stay. There are laboratories, field research infrastructure and equipments to be used for different experiments.
