TY - Data T1 - Heihe River eco hydrological remote sensing experiment: Lai 2000 measurement Lai data set in the middle reaches of Heihe River Basin (2012) A1 - Ma mingguo DO - 10.12072/ncdc.nieer.db3493.2023 PY - 2021 DA - 2021-08-27 PB - National Cryosphere Desert Data Center AB - This data is the vegetation LAI data set observed in Yingke oasis. Data observation began on May 25, 2012 and ended on July 7, 2012 Measuring instrument and principle: Lai of canopy is measured by lai2000. In the 5km * 5km quadrat of Yingke oasis, 18 corn quadrats, 1 orchard and 1 Artificial Poplar Forest quadrat were selected for measurement. The incident on the canopy is measured once in each quadrat, and the transmission under the canopy is measured many times, then the mean value is taken, and the canopy Lai is obtained through the inversion of the gap rate model Supporting data: vegetation type, plant height, ridge structure, scene photos and other information Data format: Excel format DB - NCDC UR - http://www.ncdc.ac.cn/portal/metadata/d6fdc16d-4043-45c7-9d0f-a3bd58918586 ER -
