Abstract:
Vegetation net primary productivity (NPP) is an important factor in determining ecosystem quality and carbon sink. It reflects the productive capacity and ecological process of vegetation community, and is of great significance to adjust the global carbon balance and enhance the ecological service function. Using soil respiration model and improved CASA model, combined with MODIS and meteorological data, the net ecosystem productivity (NEP) of vegetation in Qinghai since 2000 was estimated, the spatial and temporal distribution of vegetation NEP and carbon sink, the influences of precipitation and air temperature on vegetation NEP were analyzed in this paper. Meanwhile, global warming has become a hot topic since the 20th century. In this study, the timing of snow-melt is taken as an important factor to study the impact on carbon source/sink of ecosystem in Qinghai province.
