中文摘要：

作物生物量是作物长势监测以及产量估算中的一个关键指标。随着3S技术的发展,遥感数据可以为作物生物量的估算提供有力的支撑,充分发挥遥感信息的宏观及实时动态性,使在大的时间和空间尺度上进行作物的生物量估算成为可能。文章通过总结作物生物量遥感估算的研究现状,根据采用的数据源不同以及基于的模型基础不同将现有作物生物量遥感估算模型划分为6类,并对每一类模型的方法、原理、和应用进行了详细阐述,讨论分析了作物生物量遥感估算方法的发展趋势,以及各种估算方法的自身优势和仍需完善的方面,并对今后的发展进行了展望。

英文摘要：

Crop biomass is one of the key indicators not only in crop condition monitoring,but also in crop production estimation.With the development of 3S technology,it is feasible to estimate crop biomass at large scales with remote sensing.In the present paper,the researches on crop biomass estimation models with remote sensing were reviewed,and the methods of crop biomass estimation were classified into six categories according to their differences in data source and methodology.The advantages and deficiencies of each method were discussed and analyzed.Finally,the paper presents the prospect of the methods of crop biomass estimation.
