摘 要 ：本文应用Miami模型和Thornthwaite纪念模型，结合降水量、气温、蒸发量等气候资料，分别计算了广东省植被的可能净第一性生产力、谷物产量和木材生产量。并根据计算结果，绘制出植物气候生产力图。结果表明：广东省植被潜在生产力较大，因此，提高作物产量的潜力还很大；除局部小范围外，植被潜在生产力由沿海向内陆递减，并且等值线走向大致与海岸线平行；沿海的阳江、海丰和内陆的清远、佛冈等地的气候生产力最高，相反，粤北、粤东北山区和雷州半岛的生产力最低。

Abstract:According to Miami model and Thornthwaite memorial model, the net primary productivity, the outputs of cereals and wood in Guangdong Province were assessed by using data of annual temperature, rainfall and evaporation. Then, plant climatic productivity maps were drawn. The results showed that the vegetation potential productivity in most areas of Guangdong was large, and decreased gradually from the coastland to the inland,and the trend of the isopleth roughly paralled with the coastline except few areas, the highest values were in Haifeng, Yangiiang, Qingyuan and Fogang counties, on the contrary,the lowest in the north and northeast of Guangdong and on Leizhou Peninsula.
