| 摘 要： | 利用天津市20个观测点的气候资料,应用桑维斯特纪念模型估算天津市植物气候生产力,结果显示,天津市植物气候生产力呈东西走向的带状分布,最大值在北部蓟县山区,最小值在中部的武清和北辰。水分是限制天津市作物生长的主要气候因素,天津市的水分亏缺量为142.8～352.5mm。

| Abstract: | By using climatic data, the plant climatic productivity in Tianjin was calculated with Miami and Thornthwaite-Memorial model. The result showed that the plant climatic productivity was zonal distribution from east to west. The north parts of Jixian county had the highest plant climatic productivity, and the lowest plant climatic productivity lay in the middle parts of Wuqing and Beichen district. Water condition was the main limited factor for the plant climatic productivity in most regions of Tianjin. The water deficit was at the range of 142.8 - 352.5 mm. |
