YANG Hong-chang1,FAN Yuan-hong2,WU Cai-wen1,LIU Jia-yong1,ZHAO Pei-fang1(1Sugarcane Research Institute,Yunnan Academy of Agricultural Sciences,Kaiyuan,Yunnan,661600;2Yunnan Academy of Agricultural Sciences,Kunming,Yunnan 650231)  
Using the method of Lieth,the sugarcane climate potential productivity and it's reality productivity in Dehong Region were estimated and analyzed in this paper.The analysis results showed that the sugarcane climate potential productivity was southeast high and northwest low.The ratio of average reality sugarcane productivity and climate productivity was 1.50,and that of sugarcane field of High-Sugar-Yield(15 t/hm2) was 2.66.It is indicated that the actual sugarcane productivity level is still low in Dehong,and great production potential could be obtained.
