摘要
基于地理信息系统(GIS)技术和联合国粮农组织(FAO)农业生态区域法(AEZ)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均值为183.27t/hm^2,理论值范围为169.03—201.33t/hm^2,开发度均值为37.21%;光温生产潜力均值为175.51t/hm^2,理论值范围为154.19~200.75t/hm^2,光温生产潜力开发度均值为38.85%;气候生产潜力理论值范围为142.94~197.21t/hm^2,其平均值为165.88t/hm^2,现实生产潜力平均开发度为41.11%。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。
Based on the ArcGIS and AEZ models proposed by FAO,the potential of photo-thermal production and the sugarcane production in Guangxi province were investigated. The investigation demonstrated that the average po- tential photosynthetic productive potential was 183.27t/hm^2 ;the theoretical value of photo-thermal potential for sug- arcane production in Guangxi was about 169.03 -201.33t/hm^2 ;the average potential development capacity was 37.21% ;The average potential photo-thermal potential was 175.51 t/hm^2 ;the theoretical value of photo-thermal po- tential for sugarcane production in Guangxi was about 154.19 -200.75t/hm^2 ;the average potential development capacity was 38.85% ;the theoretical value of climatic potential for sugarcane production in Guangxi was about 142.94 - 197.21t/hm^2 ;the average potential development capacity was 41.11%. Results indicated that the sugar- cane production potential had a great gap between the theoretical value and reality. Therefore the development po- tential for sugarcane production in Guangxi is promising.
