摘　　要：广西的甘蔗种植面积和蔗糖产量一直稳居全国首位,每年的极端天气事件,给广西甘蔗生产带来极大的损失。针对传统的灾情调查方法费事、费力,遥感调查手段时效性滞后等问题,本文从低空无人机遥感技术应用的角度,以广西扶绥县甘蔗双高基地为研究区,进行连续的甘蔗灾情观测,利用Pix4D Mapper软件进行航拍影像拼接及正射校正,基于遥感影像分类的方法,对受灾区域进行灾情提取和分析。研究结果表明,基于低空无人机的灾情调查手段,能够迅速准确地获取灾情信息,是广西甘蔗灾情监测的一个新的热点和趋势,能够有效提升广西甘蔗灾害的预警监测水平。The planting area and sucrose yield of sugarcane in Guangxi have been ranking first in China.However,the extreme weather events every year bring great losses to sugarcane production. Thetraditional method of disaster investigation is laborious and time-consuming.Hence,this paper takes the sugarcane base in Fusui County as the research area and carries out continuous observation of sugarcane disaster from the perspective of remote sensing technologyapplication of low latitudeUAV.Pix4D Mapper software is used for aerial image mosaic and orthophoto correction. Based on remote sensing image classification method,disaster situation extraction and analysis are carried out in disaster-stricken areas. The results show that the disaster investigation method based on UAV can get disaster information quickly and accurately,which is a new hot spot and trend of sugarcane disaster monitoring andcan effectively improve the level of early warning and monitoring of sugarcane disaster in Guangxi.
