Abstract: The Qinghai-Tibet Plateau is known as the “Chinese Water Tower”, and alpine wetland is an important carrier for the Plateau water conservation. The budgets of carbon and water and the underlying mechanisms of environmental controls are essential for evaluating the ecological functions of carbon sequestration and water conservation in the alpine wetland. Based on the popular eddy covariance technique, the carbon, water, and heat fluxes of an alpine Carex pamirensis wetland ecosystem have been conducting since 2004 at the Haibei National Field Research Station for Alpine Grassland Ecosystem (i.e. Haibei Station). In order to promote the development of alpine ecology and maximize the value of data, we intend to publicly publish the carbon, water, and heat fluxes and related routine meteorological dataset of the alpine wetland. The flux and meteorological data durations range from 2004 to 2009 and from 2004 to 2010, respectively. The dataset include net ecosystem CO2 exchange, ecosystem CO2 respiration, total ecosystem CO2 exchange, latent heat flux, sensible heat flux, air temperature, air relative humidity, water vapor pressure, wind speed, wind direction, soil temperature, total radiation, net radiation, photosynthetically active radiation and precipitation at a half-hour, day, month and year scales, respectively. This dataset are expected to provide data support and theoretical foundation for regional ecological function assessment and ecological civilization construction.
