Estimation of Light Utilization Efficiency of Vegetation in China Based on GIS and RS

  • On the basis of GIS and RS technology, using the ground meteorological data and NOAA/AVHRR NDVI data, a method of light utilization efficiency (ε) is presented. The results show that the estimated annual mean ε in China varies from 0.06 gC·MJ-1 to 1.07gC·MJ-1. The standard deviation of mean ε is large, whose value is 0.169. This shows that the spatial variation of ε in Chinese vegetation is remarkable.
