TY - Data T1 - Dataset of remote sensing experiment in the Dayekou watershed in 2004 A1 - Li xin DO - 10.12072/ncdc.westdc.db3746.2023 PY - 2020 DA - 2020-04-08 PB - National Cryosphere Desert Data Center AB - From July 16 to August 6, 2004, hanhanhan Institute of Chinese Academy of Sciences organized a remote sensing experiment in the Dayekou basin of the upper reaches of Heihe River. The soil survey data of 14 profiles, DEM of 1:5000 scale in the drainage ditch basin, spectral data of typical features and ground synchronous observation data of Dapingding TM and QuickBird satellite were obtained. It mainly includes:1) Spectral measurement data of typical ground objectsThe data mainly include the spectra of Elaeagnus angustifolia, poplar, Tamarix, bark, ephedra, sand, alfalfa, corn, cotton and salinized land near Linze Inland River Basin comprehensive research station (Linze station for short), and the spectra of plum, grass, moss, bramble, alpine meadow, soil and rock in the drainage ditch basin. 2) Soil profile survey dataIn the drainage ditch basin, 12 soil profiles are set up according to the altitude and vegetation type. In addition, one soil profile is set up in the drainage ditch forestation meteorological station and Linze meteorological station respectively. The soil moisture content, bulk density, clay content and soil spectrum of 14 profiles are measured. The profiles of the drainage ditch forestation meteorological station and Linze meteorological station also measure the heat conduction and water conduction parameters of the soil. 3) Field measurement data of typical geophysical parametersIt includes leaf area index measurement data of corn, cotton, pine, alfalfa and ephedra near Linze station, leaf area index data of different height zones in the drainage ditch basin, photosynthetic characteristics data of vegetation leaves (photosynthetic rate, stomatal conductance, intercellular CO2 concentration, leaf transpiration rate, leaf temperature) and corresponding environmental factor data (atmospheric temperature, air relative humidity, large Air CO2 concentration, air water content, atmospheric pressure, total solar radiation, photosynthetic effective radiation DB - NCDC UR - http://www.ncdc.ac.cn/portal/metadata/38e0ddfa-c6a7-4bda-be38-1ad8fa459a9d ER -
