The radiation use efficiency (RUE) model suggested by Monteith in 1972 is one of the most widely applied approaches for modeling net primary production and crop yield, especially by means of remote sensing techniques. To use this approach, RUE and harvest index (HI) are the two key parameters that need to be defined, besides the absorbed photosynthetically active radiation. However, there exist some problems in the studies and applications of RUE and HI. This paper reviewed the research progress on RUE and HI, summarized the current methods and procedures for defining RUE and HI values when using the RUE approach for predicting crop yield by remote sensing, and proposed that in order to maximize the effective application of RUE and HI in remote sensing crop yield and crop production management, future researches should seek proper procedures to determine the spatial heterogeneities of RUE and HI at regional scale based on field experiments.
1972年蒙蒂思提出的辐射利用效率（RUE）模型是模拟净初级生产力和作物产量应用最为广泛的方法之一，尤其是借助遥感技术。使用该方法时，除光合有效辐射吸收量外，RUE和收获指数（HI）是两个需要定义的关键参数。然而，RUE和HI的研究与应用存在一些问题。本文综述了RUE和HI的研究进展，总结了利用RUE方法通过遥感预测作物产量时定义RUE和HI值的现有方法与步骤，并提出为了最大限度地有效应用RUE和HI于遥感作物产量及作物生产管理中，未来研究应基于田间试验寻找合适的程序来确定区域尺度上RUE和HI的空间异质性。
