摘  要:
美国国家航空航天局(NASA)成功发射了最新系列的陆地卫星(Landsat-8),搭载的陆地成像仪(OLI)对波段进行了重新调整,从而避免了大气吸收干扰,能够更好地区分植被和无植被特征,为农业遥感提供了全新的高质量数据。本文选取皖北(阜阳、蚌埠、宿州)为研究区域,以Landsat-8遥感影像为研究数据,经缨帽变换得到遥感影像的主成分信息,并用其分量甄选出不同地物的端元,最后建立线性混合像元模型(LSMM),并对皖北地区冬小麦进行提取。与历史统计数据对比,冬小麦种植面积的提取精度达到了90%以上,说明利用Landsat-8和LSMM开展大尺度范围的小麦种植面积提取具有明显的优势。

摘  要:
National Aeronautics and Space Administration(NASA)successfully launched the latest land satellite(Landsat-8).The band of operational land imager(OLI)was adjusted to avoid atmospheric absorption interference and can distinguish vegetation from no vegetation features better,thereby it provided a new high-quality data for agricultural remote sensing.This study selected the northern Anhui(Fuyang,Bengbu,Suzhou)as the study area and took Landsat-8remote sensing image as the research data,and principal component information was used to extract pure/mixed pixel of winter wheat though tasseled cap transformation in order to select the end-member of different objects.Finally,the winter wheat planting area of northern Anhui was calculated by establishing linear spectral mixture model(LSMM),and the accuracy exceed 90%after verification.In summary,the extraction of winter wheat area based on Landsat-8and LSMM in large scale range had obvious advantages.
