摘　　要：为提高广西甘蔗生产水平,合理开发自然资源,在GIS技术和FAO农业生态区域法（AEZ）的支持下对广西甘蔗生产的光温生产潜力、气候生产潜力进行估算。结果表明,广西甘蔗光合生产潜力的均值为183.27 t/hm^2,理论值范围为169.03-201.33 t/hm^2,开发度均值为37.31%;光温生产潜力均值为175.51t/hm^2,理论值范围为154.19-200.75 t/hm^2,开发度均值为39.12%;气候生产潜力均值为165.88 t/hm^2,理论值范围为142.94-197.21 t/hm^2,开发度均值为41.71%。由此可知,广西甘蔗生产潜力理论值与现实生产力之间的差距较大,开发前景广阔。In order to improve the production level of sugarcane in Guangxi Zhuang Autonomous Region and promote the rational exploitation,the sugarcane production potentialities of photosynthesis,temperature,climate were estimated under the support of GIS and FAO in Guangxi.Results showed that the average potential of photosynthetic production was 183.27 t/hm^2.The theoretical value of photo-thermal potential for sugarcane production in Guangxi was 169.03 -201.33 t/hm^2.The average potential of development capacity was 37.31%.The average photo-thermal potential was 175.51 t/hm^2.The theoretical value of photo-thermal potential for sugarcane production in Guangxi was 154.19 -200.75 t/hm^2.The average potential development capacity was 39.12%.The average climatic productivity potential was 165.88 t/hm^2.The theoretical value of climatic potential for sugarcane production in Guangxi was 142.94 -197.21 t/hm^2.The average potential of development capacity was 41.71%.The difference between practical sugarcane productivity and potential sugarcane productivity was still big,indicating that there was wide prospect in the development and utilization of sugarcane.
