[Objective] Climatic productivity was applied to forecast and analyse the vegetable yield. [Method] Climatic productivity model presented by Zhou and the long-range climate forecasting method were adopted to analyse characteristics of the change of climatic productivity potential at Beibei District in combination with the ac- tual vegetable yield. [Result] The change of climatic productivity at Beibei District was fluctuant in an stable overall trend. The difference of spatial distribution of cli- matic productivity was apparent, with high climatic productivity potential in the north- east; in the actual production, vegetable yield was declining and it was the same with the climate use efficiency; according to the prediction, the vegetable yield would increase slightly in the future 10 years. [Conclusion] This study provides bases for the reasonable plan and layout of vegetable plantation under the climatic condition at Beibei District, as well as the selection of vegetable cultivars.
