国内外农作物遥感估产的研究进展

Research on the Progress of Domestic and Foreign Crop Yield Estimation by RS

本文按照发展进程—过程方法—产生问题—提出对策的思路,论述了国内外遥感技术在农作物类型识别方法和面积提取方法的研究进展和存在的问题。阐明研制高光谱和超高光谱传感器是遥感影像获取技术的发展动态;获得高空间分辨率影像,优化和改进影像分类方法和面积提取方法,建立农作物长势监测和灾害预警系统,并与GIS和GPS技术集成应用,是遥感技术在农业领域应用的发展趋势。

This paper discusses the research progress and existing problems of the application of RS technology in domestic and foreign crop types’ identification and area extraction method.The further developments of RS image acquisition technology focus on the preparation of high spectral and hyper spectral sensor.In addition,this paper also illustrates the development trends of the RS application in the field of agriculture,which includes obtaining high spatial resolution images,optimizing and improving the image classification and area extraction method,establishing crop growth monitoring and disaster warning system,and the integrating of GIS and GPS technology as well.
