摘　　要：利用FY-3A/VIRR数据,基于植被供水指数法(VSWI),监测重庆市2011年盛夏干旱演变过程.利用全市150个土壤水分观测站点的数据和同期遥感反演结果进行相关分析,均达到极显著性相关;监测显示8月中下旬重庆市出现比较严重的干旱,特别是中部和西南部重旱一直持续.结果表明,FY-3A/VIRR遥感反演数据能够客观反映重庆地区的干旱演变过程,可应用于干旱监测业务.The method of vegetation supply water index （VSWI） and the FY-3A/VIRR data were used in this study to monitor the evolution of drought in mid-summer of 2011 in Chongqing. The data of soil mois- ture recorded at 150 observation stations of Chongqing and the remote sensing inversion results for the same period were used for correlation analysis, and the results were all highly significant. The results of the monitoring demonstrated that a relatively serious drought occurred in middle and late August, and that the drought lasted for a long time in the central and southwestern regions of the city. It is concluded from the above results that the vegetation supply water index used in combination with FY-3A/VIRR data can obiatiuolu rotrioun the drought monitoring and therefare in agghle for drought mgnitoring in Chongqing
