Chinese. [目的]应用气候生产力对蔬菜产量进行预测分析。[方法]利用气候生产力模型和长期气候预测方法，结合实际蔬菜产量分析了北碚区气候生产潜力的变化特征。[结果]北碚区气候生产力呈波动变化，总体趋势稳定，空间分布差异明显，东北部生产潜力较好；在实际生产中蔬菜单产在下降，气候利用率也呈下降趋势；据预测，未来10年，蔬菜产量将出现小幅度的增长。[结论]该研究为针对北碚区气候条件下蔬菜种植的合理规划和布局以及蔬菜种植品种的选择提供了依据。

[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 actual vegetable yield. [Result] The change of climatic productivity at Beibei District was fluctuant in an stable overall trend. The difference of spatial distribution of climatic productivity was apparent, with high climatic productivity potential in the northeast; 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.
