Study on Zonal Net Primary Production Estimation Model Using Landsat Data
植被净初级生产力的遥感模型在武汉地区的应用

Remote sensing was used as a powerful approach to estimate and supervise net primary productivity of terrestrial vegetation, for it is free from hard field works and realizes the estimation of NPP in a large region. A new vegetation index was developed based on pattern decomposition method and light\|use efficiency model was taken to estimate NPP of Wuhan (mostly subtropical evergreen\|deciduous forests) using Landsat\|ETM data. The result was compared with the ones obtained by LUE model and other field investigation.
