Li, SH; Xiao, JT; Hu, ZC; Li, ZY; Zhao, LS (2012). Spatial Scaling Analysis in Gross Primary Production Estimation. ADVANCES IN COMPUTATIONAL ENVIRONMENT SCIENCE, 142, 259-263.
Spatial scaling is very important to evaluation terrestrial carbon balance. In this paper, Gross primary production (GPP) are calculated using the Region Production Efficiency Model(REG-PEM) based the Moderate Resolution Imaging Spectrometer(MODIS) and Landsat TM data, respectively, and some issues related to spatial scaling are analyzed. The minimum and maximum values of parameters and GPP are significantly different at different scale. The mean values of parameters and GPP based on TM image are smaller than that based on MODIS image.
