【摘要】 广西是我国最大的蔗糖产地,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。本文利用多时相HJ-1 A、B星CCD图像开展广西崇左市甘蔗长势、种植面积、收割过程和总产估算遥感监测。结果表明:(1)10月底11月初的环境星CCD图像提取甘蔗信息效果较好。这一时相,综合利用多光谱信息,可以较好地排除其他地物,提取甘蔗信息。(2)环境星CCD图像能够满足影像数据时相要求较高的农作物遥感监测的要求。在夏秋季节甘蔗关键生育期,多云多雨,环境星CCD图像大幅宽快重访的特点也能够获得比较理想的图像,对甘蔗长势进行监测;在甘蔗榨季,多时相的环境星CCD图像,可以跟踪甘蔗的收割过程,进行甘蔗收割过程的监测。更多还原

【Abstract】 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 will be used to monitor sugarcane growth condition,extract sugarcane plant area,monitor sugarcane harvest process,and estimate the total yield in Chongzuo,in Guangxi province.The research shows that:(1) HJ-1 A,B satellite CCD data in October late or November early can meet the requirement of extracting sugarcane plant information and eliminate the other things.(2) The multi-temporal HJ-1 A,B satellite CCD data can be used to monitor the sugarcane growth condition in summer or autumn when thole ale many cloudy or rainy days,and to monitor the sugarcane harvest process.The data can meet the requirement of monitoring crop growth which need high-temporal remote sense data.更多还原
