摘　　要：广西是中国最大的蔗糖产地,种蔗面积和蔗糖产量均占全国的约60%。及时、准确地监测广西甘蔗种植和收割信息,对于甘蔗生产具有重要的意义。该文采用多时相HJ-1A、B星CCD图像开展广西扶绥县甘蔗种植和收割信息提取及面积估算示范研究。选取从2009年11月5日到2010年2月19日共四个时相CCD图像,逐时相提取甘蔗信息,通过叠加运算,得到相邻两个时相期间甘蔗收割范围和收割面积,完成对2009/2010榨季甘蔗种植和收割情况的遥感监测。研究表明,1)在适当的时相下,HJ-1A、B星CCD图像的空间分辨率,波段设置和辐射分辨率,能够满足县域及以上区域尺度下地物复杂地区进行大宗农作物种植信息提取和面积估算的应用需求;2)多时相HJ-1A、B星CCD图像能够监测甘蔗收割过程,可以满足时相要求较高的农业资源调查统计遥感应用的要求。Guangxi Autonomous Region is the largest sugar production area in China,whose sugarcane planting area and sugar production account for about 60% of the country.Timely and accurately monitoring sugarcane planting and harvesting information is of great significance for sugarcane production.The multi-temporal HJ-1 A,B satellite CCD data were used to extract the sugarcane planting and harvesting information and area in Fusui county,Guangxi Autonomous Region.In this paper,We chose four temporal images from Nov.5th,2009 to Feb 19th,2010 and extracted the sugarcane information in each image,then overlaid the adjacent temporal sugarcane information and got the harvest area during the period.The research showed that：1） The spatial resolution,waveband,radiation resolution of HJ-1 A,B satellite CCD data can meet the requirement of extracting main crop growth information and calculation area in complex land cover area at county scale and above;2） The multi-temporal HJ-1 A,B satellite CCD data can be applied to monitoring the sugarcane harvest process and survey and statistic of agricultural resources which need high-temporal remote sense data.
