| 英文摘要 | After analysing formulations of the horizontal wind velocity above a nonuniform underlying surface, it is found that the mean height of roughness elements, fractional vegetation cover and leaf area index are the most essential parameters of vertical wind profile under neutral conditions. By using Landsat-5 data, every-10-days observed data in the field, the every-10-days Normalized Difference Vegetation Index (NDVI) data from NOAA-14 meteorological satellite, 1 : 10000 land-use data, and 1 : 10000 topographical data, the mean height, leaf area index and fractional vegetation cover of wheat at Yucheng Integrated Agricultural Experiment Station are simulated as functions of NDVI. Then, hourly horizontal wind velocity at a height of 4m during the period from 21:05 on 5 March 2000 to 7:05 on 24 May 2000 is calculated, for which hourly observed horizontal wind velocity at a height of 2m is first used to simulate the wheat parameter of the dimensionless constant. The results show that the simulated velocity is almost identical to the observation velocity at a height of 4 m. |
