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。
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 evaluation indexes of drought were 35.4 and 24.4 resp.Its drought was lighter in 2005,2008 and 2007 and their integrated evaluation indexes of drought were 0.1,0.2 and 0.8 resp.
