Advance in Research on Net Primary Productivity of Terrestrial Vegetation
陆地植被净初级生产力研究进展

Annual net primary productivity(NPP) of terrestrial vegetation is the net amount of carbon fixed by plant photosynthesis.NPP is an important index in global change ecology.This paper summarized the advance in research on net primary productivity of terrestrial vegetation over globe or regions in home and abroad for the recent years.It also analyzed the application of remote sensing and geographic information system in NPP research.At the same time,the feature and the trend of researching NPP are discussed.
