| 摘 要： | 以广西甘蔗主产区的崇左市蔗区为研究区,基于MOD IS数据,采用植被温度指数模型对2004~2008年研究区发生的秋季甘蔗旱情进行遥感监测,并利用旱情综合评价指数对研究区进行旱情综合评价。结果表明,2004~2008年5年中,研究区2004和2006年干旱最严重,旱情综合评价指数分别为35.4和24.4;2005、2008及2007年干旱较轻,旱情综合评价指数分别为0.1、0.2和0.8。

| Abstract: | With major sugarcane production area of Guangxi,Chongzuo City as the studied area,based on MODIS data,the vegetation-temperature index model was used for remote sensing motoring on autumn drought of sugarcane,which occurred in the studied area in 2004-2008.And the integrated evaluation index of drought was used for integrated evaluation on drought in the studied area.The results showed that in the 5 years from 2004 to 2008,the drought of Chongzuo City in 2004 and 2006 was the severest and their integrated e... |
