The Zoige Wetland Research Station is located in Hongyuan County, Aba Autonomous Prefecture, Sichuan Province (Coordinate: 32°58' 04.41"N, 102°36' 59.68"E),with an elevation of 3465m a.s.l. The station represents sub-alpine meadow and peatland.


The region belongs to cold-temperate monsoon climate, with an annual mean air temperature of 1.4℃ and an annual precipitation of 749.1mm.

Vegetation and soil

The dominant plants are species of Cyperus, Gramineae, and shrubs. Soil types include sub-alpine meadow soil, bog soil and peat soil.

Observation system

Meteorological station, open-path eddy covariance system, chamber system for GHG fluxes monitoring.

Low atmospheric pressure as a driver of methane ebullition from alpine laks      (Dan Zhu   2013-2015 )




We launched several research projects to observe different aspects of meadow conservation and management. In site 1, various ways of sustainably utilizing meadow is conducted, including selecting combinations of various native plant species under different management strategies, successful combinations of which would then be introduced in a wider geographical area for multiple objectives such as restoration of degraded meadow, high altitude pasture management, etc. Site 2 demonstrates monitoring of carbon and nitrogen cycling under contemporary climatic conditions as well as simulated climate scenarios. This would have implications for enhancing carbon sequestration and reducing greenhouse gas (GHG) emissions from peatlands, while optimizing peatland management as an effective approach for climate change mitigation
