摘　　要：目前遥感技术越来越广泛地应用于农作物面积的估算,本文研究了基于高分辨率卫星影像的农作物面积测量技术,提出一种冬小麦种植面积估算模型。该模型采用最大似然法对遥感影像进行监督分类,利用耕地矢量数据优化分类结果,结合高分辨率样本村数据拟合估算冬小麦种植面积。以泗洪县为研究区,采用GF-1卫星数据完成了泗洪县冬小麦面积提取实验,验证了该模型的有效性。At present,remote sensing technology is more and more widely used for estimating crop area.In this paper,the technology of crop area measurement based on high resolution satellite images is studied,and a model for estimating the planting area of winter wheat is proposed.The model first uses the maximum likelihood method to supervise and classify the remote sensing images,and then optimizes the classification results by using the cultivated land vector data.At the end,winter wheat area is obtained by combining the high-precision data of the sample village data to estimate the crop area.Finally,taking Sihong County as an example,the area extraction experiment of winter wheat based on GF-1satellite data is carried out to verify the effectiveness of the model.
