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）. Luancheng Station is located in Luancheng county of Hebei province (37°53' N, 114°41'E and elevation at 50.1 m), represents the typical high production area in the northern part of the North China Plain. 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.

Located in the Cape Horn Biosphere Reserve (UNESCO 2005), the southernmost part of Chile, the Omora Park has a mountain landscape covered by subantarctic forests and wetlands. Omora Park is a botanical garden and protected area, in the north of the Navarino Island, Cape Horn, Region of Magallanes, on the southern shore of the Beagle Channel. This park develops scientific research, education, philosophy, ethics and conservation of the species of the Chilean southern region.

This site experienced peat extraction. It contains Sphagnum plots and Vaccinium oxycoccos, but the peatland is dominated by graminoids forming tussocks.

The Fray Jorge experimental site is located inside the Fray Jorge National Park, in the Region of Coquimbo. Its characteristic vegetation is Mediterranean and at the top of the coastal range exists evergreen temperate forests (cloud forests). The climate is Mediterranean with coastal influence.

The Mase rice paddy site is a flux station in the AsiaFlux micrometeorological tower network. Located in a regularly cultivated rice paddy area of the Kanto plain in Japan, the site was established in 1999. The initial motivation was to quantify the energy and carbon balance in the rice paddy (ca, 54 a) where the tower was situated. Because of the accessibility and line-power availability, the site has involved many researchers and students from universities and institutes, broadening its target to studies on satellite and field remote sensing, ecosystem modelling, and nutrient cycling.

The Jiaozhou Bay, covering an area of 390 km2 between 3538′ and 3618′ N and 12004′ and 12023′ E, surrounded by the Qingdao city. As a semi-enclosed, fan-shaped bay, the narrowest place at the channel connecting with the Yellow Sea, from the Tuan Island to the Xuejia Island, is only 3000 m wide. Its average depth is 6-7 m, with most part of the bayshallower than 5 m, and the tidal zone adds up to 125 km2. The tide of Jiaozhou Bay is regular semidiurnal type. The speed of the flood is greater than that of the ebb, and the duration of the flood is shorter than that of the ebb. There are many peninsulas and islands in the bay, so the circulation inside is complicated. After the residual current analysis, six circulation systems were observed in Jiaozhou Bay. Marine biodiversity and productivity is high in the bay. With the development of Qingao City, the population is increasing quickly around Jiaozhou Bay. Farms, factories, highways, ports, tourism etc. can all affect the environments of the bay. Most of the land-sourced input are from several rivers, such as the Dagu, Haibo, Licun and Nan Jiaolai rivers.

Curonian lagoon biosphere polygon is a part of ecologic and specialized monitoring system for biological diversity and NATURA2000.

It is located in the region of the Grand Causses, south of the Massif Central. The karstic aquifer of Durzon represents a surface of 100 km² which feeds the spring of Durzon. This spring supplies the drinking water of the Aveyron part of Larzac. The observatory has a set of sites dedicated to gravimetric, inclinometric and hydro-geodesic observations, as well as a flow tower for evapotranspiration measurements.

The Sany Bay, covering an area of 120 km2 between 109.3333 and 109.5 E and 18.183 and 18.3 N, surrounded by the Sanya city. It is a typical tropical bay in China. Dongmao Island, Ximao Island and Luhuitou, located in the bay mouth, possess mostly coastal coral reefs. The Sanya River, located in the eastern part of the bay, has many kinds of tropical habitats including coral reefs, mangroves, rocky and sandy shores, mudflats, etc. The coral reefs and mangroves have special resource value and ecological benefits and are, therefore very important to the sustainable social and economical development in these tropical coastal areas. Coral reefs and mangrove areas have important relationships to the regulation and optimization of the tropical marine environments.

Qianyanzhou Agricultural Experimental Station of Red Soil and Hilly Land, was founded as a pilot experimental site for ecological recovery in South China In 1983. In 1985, it was selected as an Integrated Development Demonstration Base of Mountain-Lake-River Project of Jiangxi Province. In 1992, as an international experiment station, it was nominated by MAB as a training center of UND Jiangxi Project. Qianyanzhou Station became a member of CERN in 1991 and a member of ChinaFLUX in 2002.
