Abstract: The photosynthesis productive potential,lighttemperature 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.
