粮食作物播种面积遥感监测研究进展

Review of research advances in remote sensing monitoring of grain crop area

摘要: 介绍了遥感监测粮食作物播种面积的理论和现实意义,回顾了国内外基于常规方法、线状框架采样、面积框架采样、光谱混合模型(spectral mixture model , SMA)等方法进行植被制图和进行粮食作物识别研究的现状和存在的问题, 并对基于波谱库的农作物播种面积监测提出了建议。

Abstract: The theoretical and practical meaning of remote sensing monitoring of crop area is introduced. The present situation and existing problems of vegetation mapping and crop identification research at home and abroad based on routine method, linear frame sampling, area frame sampling, geographical knowledge base, spectral mixture model are reviewed. Suggestions are put forward for spectral library-based crop area research and application expanding.
