Luancheng station, established in 1981, is one of the field stations of the Chinese Ecosystem Research Network (CERN) and a member of Global Terrestrial Observation System (GTOS). The station is also a demonstration base for modern agricultural technologies in Hebei province. In 2005, the station became one of the stations of the China National Ecosystem Observation and Research Network（CNERN）.

The rapid declining groundwater table has become the main problem that threatens the sustainable agricultural development in this area. The researches conducted at the station focus on the long-term investigations of farmland ecosystem, water and nutrients transfer and regulation mechanisms, modern water-saving technologies, molecular breeding, precision agriculture and regional sustainable agro-ecosystem demonstration models etc.. The station has 28 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.
