摘要:青藏高原被誉为“中华水塔”,高寒湿地是其水源涵养的重要载体,其碳水热收支特征及环境控制机制是评估湿地碳素固持和水源涵养等生态功能的关键。基于涡度相关技术,青海海北高寒草地生态系统国家野外科学观测研究站(简称海北站)自2004年至今一直开展高寒帕米尔苔草(Carexpamirensis )湿地生态系统碳水热通量的科学观测。为了促进高寒湿地生态学发展和数据价值最大化,海北站拟公开发表2004–2009年高寒湿地连续观测的碳水热通量及相关常规气象数据集,具体包括净生态系统CO2交换通量、生态系统CO2呼吸通量、总生态系统CO2交换通量、潜热通量、显热通量、空气温度、空气相对湿度、水汽压、风速、风向、土壤温度、总辐射、净辐射、光合有效辐射和降水等观测指标,数据集的时间尺度包含半小时、日、月和年,以期为区域生态功能评估和生态文明建设提供数据支撑和理论依据。

Abstract & Keywords
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.
