Abstract: The Qinghai-Tibet Plateau is known as the “Chinese Water Tower”, and alpine wetlands are an important carrier for the Plateau water conservation. The budgets of carbon and water and the underlying environmental control are essential for evaluating the ecological functions of carbon sequestration and water conservation in the alpine wetlands. Based on the popular eddy covariance technique, the carbon, water, and heat fluxes of an alpine Carex pamirensis wetland has been conducting since 2004 at the Haibei National Field Research Station for Alpine Grasslands (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 data sets of the alpine wetlands from 2004 to 2009. 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 scale, respectively. This dataset are expected to provide data support for regional ecological function assessment and ecological civilization construction.
