摘　　要：为确定马铃薯的高产目标,采用两种估算光合生产潜力的方法对内蒙古马铃薯主产区乌兰察布地区的马铃薯产量潜力进行了估算和比较,提出了适合当地马铃薯光合生产潜力估算的修正模型。计算得出内蒙古阴山北麓地区马铃薯的光合生产潜力为82 503.1kg/hm2,光温生产潜力为65 619.7kg/hm2,平均降水生产潜力为47 897.6kg/hm2,该结果为确定当地产量目标提供了理论依据。Two models were used to estimate and compare potato potential productivities at the major growth area, the north Yin mountain area in Inner Mongolia. Modified potential productivity model of potato was proposed and considered to be suitable for photosynthetic potential productivity estimation at local area. According to the model the estimated values of photosynthetic potential productivity, photosynthetic thermal productivity and rainfall produc- tive potential were 82 503.1 kg/hm^2 ,65 619.7kg/hm^2 and 47 897.6kg/hm^2, respectively. The results would provide a theoretical basis for setting high-yield at the local area.
