摘要：

Climatic warming due to increased concentrations of greenhouse gases in the atmosphere is likely to lead to large-scale shifts in the pattern of agricultural potential. This article reports the results of a study to investigate the broad-scale sensitivity of crop potential to climatic change in Europe. A simple agroclimatic index, effective temperature sum (ETS), has been related to the minimum requirements for the successful cultivation of three crops: grain maize, sunflower and soya bean. With the aid of a computer mapping system, ETS has been mapped across Europe on the basis of present climate and of scenarios of future climate. In this way, the effects of changes in climate can be expressed as spatial shifts in the limits of crop potential, and the uncertainities in the estimates can be interpreted in terms of the likelihood of particular regions becoming climatically suitable for crop cultivation. The estimates point to a considerable dislocation of agricultural potential occurring over a matter of only several decades.
