GF-1 domestic high resolution satellite remote sensing data had the advantages of high spatial resolution , high time resolution and high spectral resolution.The GF-1 satellite remote sensing data of wide field were used.Based on the GPS field sampling, Enhanced Vegeta-tion Index (EVI) was used to extract the multi-temporal rice growth information in Jianhu County in 2014.results showed that wide-field image of GF-1 satellite could clearly reflect the elements of rice growth vigor, and could be applied in the extension of yield estimation with remote sensing.%GF-1国产高分辨率卫星遥感数据具有高空间分辨率、高时间分辨率和高光谱分辨率的优点。该研究利用GF-1卫星宽视场遥感数据，在GPS实地取样的基础上，利用增强型植被指数（EVI），提取建湖县2014年多时相水稻长势信息。结果显示，GF-1卫星宽视场影像可以清晰反映水稻长势要素，能够在遥感估产中推广应用。
