Abstract Several studies have estimated the potential effects of greenhouse gas-induced climate change on various systems using outputs of general circulation models (GCMs). The purpose of the present study was to generate comparable estimates of potential impacts on net primary production using the GCM climate scenarios in a very simple net primary production model and to identify the most likely limiting factor that would follow a change in global climate. The study emphasizes that climatic thresholds that limit production across China will be modified following a doubling of atmospheric CO2 concentration. Detailed studies are underway to determine the direct impacts of such changes on the water budgets of both natural and agricultural ecosystems in western China. Detailed observations of vegetation response to past drought and flood years would be of great interest in order to better predict what might happen in the future, given the physiological changes that have been documented to occur when plants are grown at elevated carbon dioxide concentrations.
