Abstract: In this paper, the outputs of 3 general circulation models (i. e., GISS, OFDL and UKMO) were employes as a basis on computer for constructing the regional climate scenarios with doubled CO_2 concentrations in China, combined with 20-30 years historic weather data, By which, the aurthors disccussed the distributional features and seasonal changes of temperature, precipitation and solar radiation under doubled CO_2 scenarios and also estimated the vulnerable regions of global climate change in China. The results could provide necessary information for assessing the implication of climate change in China.

Key words: Climate warming General circulation model. Regional climate scenarios., Climate warming General circulation model. Regional climate scenarios.
