摘　　要：采用作物生长动态统计模型对塔里木河流域阿克苏地区主要农作物的光合、光温、光温水、光温土、光温水土生产潜力进行了计算和分析。结果表明:阿克苏地区主要农作物的光合生产潜力远大于现实生产力,冬小麦、玉米、水稻、棉花的光合生产潜力分别是实际产量的4.14、3.94、2.73、2.41倍;光温生产潜力相当于光合生产潜力的57.26%,光温水(气候)生产潜力只有光温生产潜力的9.55%,而土壤生产潜力占光温水(气候)生产潜力的49.92%。该地区光热资源丰富,其光热条件是作物气候生产潜力最突出的优势,土壤水肥条件是限制作物气候生产潜力的主要可控因子。The photosynthesis productive potential,light-temperature productive potential,light-temperature-water productive potential,light-temperature-soil productive potential and light-temperature-water-soil productive potential of main crops for Akesu Area in Tarim River Region were calculated and analyzed by using the revised model of crop growth and development dynamic statistics. The results showed that the photosynthesis productive potential of main crops in Akesu area was far larger than realistic productivity. The photosynthesis productive potential of winter wheat, maize, rice, cotton was more than the realistic productivity with 4.14,3. 94,2.73 and 2.41 times respectively. The light-temperature productive potential was 57.26% of the photosynthesis productive potential. The light-temperature-water productive potential, e. g. so-called climate productive potential,was only 9.55% of light-temperature productive potential. The soil productive potential was 49.92 of the light-temperature-water productive potential. It was concluded that the light-heat resources in Akesu Area was plentiful and the conditions of light and heat were most outstanding advantage for climate productive potential. The soil water and soil fertility were the main controllable factors that limited climate productive potential.
