2012-2016年三江源垂穗披碱草人工草地碳水热通量观测数据集
A dataset of carbon,water and heat fluxes over an Elymus nutans artificial grassland in the Sanjiangyuan Area(2012-2016)
摘要
Abstract
In the Sanjiangyuan Area known as the"Chinese Water Tower",planting perennial artificial grassland has become an important measure for the restoration of degraded grassland in this area.The spatial-temporal pattern of the carbon,water,and heat fluxes of Elymus nutans artificial grasslands are crucial for comprehending the ecological service functions of the Elymus nutans artificial grasslands in the Sanjiangyuan Area.Sanjiangyuan Grassland Ecosystem National Observation and Research Station(referred to as Sanjiangyuan Sation)has used the eddy covariance technique to monitor the carbon,water,and heat fluxes over an Elymus nutans artificial grassland for 5 years since 2009.In order to advance the research on carbon,water,and heat fluxes and other related researches in the Sanjiangyuan Area and the broader Qinghai-Tibetan Plateau alpine ecosystems,we plan to publish the routine meteorological data of carbon,water and heat fluxes over an Elymus nutans artificial grassland observed from 2012 to 2016.This dataset includes routine meteorological data(i.e.air temperature,air relative humidity,water vapor pressure,soil temperature,soil moisture,photosynthetically active radiation,and precipitation)and carbon,water,and heat fluxes data(net ecosystem CO2 exchange,ecosystem CO2 respiration,gross ecosystem CO2 exchange,latent heat flux,and sensible heat flux)on half-hourly,daily,monthly,and yearly scales.The dataset used the flux data processing method recommended by ChinaFLUX.It is expected to provide field observational data support for scientific understanding,remote sensing retrieval processes,and model validation efforts in exploring the spatiotemporal patterns of carbon,water,and heat exchanges in artificial Elymus nutans grasslands.关键词
