Abstract: Drought was one of the most serious disasters in sugarcane production in China, as more than 80% of sugarcane was planted on arid land without irrigation. The research method of remote sensing monitoring on sugarcane droughts was studied in main sugarcane production area of Guangxi province with the DI model resulted from Vegetation Condition Index (VCI) and Temperature Condition Index (TCI), by using MODIS satellite data and ETM satellite data. The model was applied to monitor sugarcane droughts in the fall of 2004 and 2005, as the results, remote sensing map of temporal and spatial distribution was made. The simulated results accorded with droughts situation in reality, which indicated that the model could apply to monitor local sugarcane droughts.
