摘要:
As a powerful approach,the advantage of usig remote sensing to estimate and supervise net primary productivity of terrestrial vegetation lies not only in that it is free from a lot of trivially detailed field works,but also in that it realizes the estimation of NPP in a large region.So it largely pushes forward global change research.According to this kind of approach,this paper mainly discusses on the role of vegetation index,PAR and light energy efficiency on the estimation of NPP,and puts forward a few suggestions on improving the NPP models.
