摘要
作为一个农业大国，中国的农业生产在世界占有重要地位．建国以来，我国农业生产的物质条件得到了极大改善，生产水平持续提高．但同时对环境也发生了深刻作用，突出表现在自然植被的破坏、土地的退化、水质的恶化等，从而影响到地表物质循环过程，对全球变化产生影响。另一方面，全球变化将对中国的农业生产产生直接和间接的作用，因此进行全球变化中的中国农业发展的适应对策研究势在必行．它包括弄清气候变化的区域性及不确定性，气候变化对农业影响的不确定性，以及对该影响作出综合评价．
Chinese agriculture has occupied an important place in the world. Since liberation, Chinese agricultural conditions have been improved greatly, and the crop yield level has been raised. At the same time of the development, human action has the impacts on natural environment such as deforestation, land degradation and deterioration of water quality, which interfere with substance circulation in land surface. Otherwise, global change has direct and indirect effects on Chinese agriculture. It is necessary to access impacts of global change on agriculture for policy-making. The research of impact assessment includes the uncertainty regionalization of climatic change, the uncertainty of climatic change impacts, and synthetic evaluation of climatic change impacts.
