中文摘要：

采用MODIS温度成品数据和植被指数数据构建Ts-EVI特征空间,对四川省2007年7—10月的旱情进行监测.监测结果表明：Ts-EVI特征空间在旱情监测上有一定的优越性,能准确监测四川省2007年7—10月的旱情变化;当年四川省境内旱情严重,中旱和重旱面积占全省总面积的50%以上,川东旱情较川西高原严重,且不同区域的旱情发展态势不同;对比ECMWF土壤水体积数据,两者相关性较高.

英文摘要：

Ts-EVI feature space is constructed by using MODIS temperature data and vegetation index data tomonitor the drought in July to October 2007 in Sichuan province. The results show that the Ts-EVI feature space has acertain superiority in drought monitoring,and it can accurately monitor the drought change from July to October inSichuan province. In the year,the drought situation in Sichuan province is serious. The drought and heavy droughtareas reach more than 50% of the total area of the province. The drought in the eastern Sichuan is more serious thanthat in the western Sichuan Plateau,and the development trend of drought in different regions is different. Comparedwith ECMWF soil water volume data,we find the correlation is high.
