Sugarcane climatic yield predicting model of Nanning

Based on the spatial distribution of meteorological hazards of Nanning and the eco -physiological characteristics of sugarcane, using HJ-1 CCD satellite data, basic meteorological data and geographic information data, established a sugarcane climatic yield predicting model of Nanning. The results showed that there was a wide field of region (346.20 km2, 18.88%) sugarcane distribute on the most droughty area, while only a few of them (67.1 km2, 3.75%) distribute on the most frost injury area in 2010. The sugarcane climatic yield in the year of 2010 was up to 8.8446 million ton. The forecast accuracy was proved to be satisfactory with a accuracy ratio more than 90%.
