摘要: 目前80%以上的糖料甘蔗分布在缺少灌溉条件的旱坡地上,旱害已成为影响甘蔗生产最频繁、范围最广、损失最严重的自然灾害之一。本文选取了广西来宾市兴宾区凤凰镇这个具有代表性的大面积连片、连年种植的甘蔗区,利用高时间分辨率的MODIS卫星数据,采用植被状态指数(VCI)和温度条件指数(TCI)构建干旱指数(DI)遥感监测模型,并融合具有高空间分辨率的ETM卫星数据,进行甘蔗干旱遥感监测方法研究。应用该模型进行2004年和2005年秋季甘蔗旱情监测,制作了旱情时空变化的遥感图像,通过与旱情实况数据对比分析,证明该模型适用于甘蔗旱情监测。

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.
