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/hm2,理论值范围为169.03~201.33t/hm2,开发度均值为37.21%;光温生产潜力均值为175.51t/hm2,理论值范围为154.19~200.75t/hm2,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/hm2,其平均值为165.88t/hm2,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 Geographic Information System (GIS) technology and the FAO (FAO) Agro-Ecological Zone Act (AEZ), the potential of light-temperature production and climate potential for sugar cane production in Guangxi was estimated. The results showed that: the average potential of photosynthetic production of sugarcane in Guangxi was 183.27t / hm2, the theoretical range was 169.03 ~ 201.33t / hm2, the average development potential was 37.21%; the mean potential of light and temperature production was 175.51t / hm2, the theoretical range was 154.19 ~ 200.75t / hm2, the mean value of potential productivity of light and temperature production was 38.85%. The theoretical potential of climate productivity ranged from 142.94 to 197.21t / hm2, with an average value of 165.88t / hm2. The average development potential of actual production potential was 41.11%. It can be seen that the gap between the theoretical value of sugarcane production potential in Guangxi and the actual productivity is large, and the development prospect is broad.
