The net primary production (NPP) of Chinese terrestrial vegetation during 1982—1999 (excluding 1994 because of missing data) was estimated, and its spatio\|temporal patterns were explored, based on the CASA (Carnegie\|Ames \|Stanford Approach) model and using remote sensing imagery (NOAA/AVHRR) and land spatial data of vegetation, climate, soil and solar radiation. As results, terrestrial NPP in China indicated a significant increase over the past 18 years, with an average value of 1 8?PgC and a mean incre...
