Based on data from the intensified observational period over spring wheat field area at the arid meteorology and ecological en-vironment experimental station in Dingxi of Gansu Province from June to August 2003,which is located in the semi-arid rain fed agri-cultural region of Loess Plateau,the aerodynamic roughness Z0m ,the thermodynamic roughness Z0h and the excess resistance to heat transfer kB-1 were calculated and analyzed,firstly.Then,the spatial distributions of Z0m and kB-1 over eastern part of northwest China were obtained,accompanied by vegetation index Indv and surface temperature Ts derived by satellite,respectively.The above parame-ters can be used to estimate the heterogeneous land surface energy flux.
