Cotton models could be divided into three categories, physiological models, structural models, and functional-structural models. In this paper, peer review of advantages and limitations of each category of models provides an important quality-control step in the development of the cotton models. It could be concluded that cotton simulation in the future should focus on the functional-structural cotton models, which intends to bridge the gap between physiological models and structural models. However, functional-structural models of cotton still have some limitations, which are: accurate simulation of light microclimate in the canopy has not been realized; distribution of photoassimilation is less well studied; and coupling simulation of the shoot and root system is not included. Several recommendations for further improvement of the functional-structural model were also put forward in this review: light microclimate in the cotton canopy could be modeled by surface-based model; distribution of photoassimilation of shoot could be simulated by source-sink model; and coupling simulation of the shoot and root system could be realized by connecting the shoot, which is regarded as a source of assimilation, with a growing branching structure of root.%该文对棉花生理生态模型、棉花形态结构模型以及棉花结构功能模型的研究动态进行了综述,提出将形态结构和生理生态过程紧密结合的棉花结构功能模型的研究应是今后棉花模拟研究的重点,指出了目前生理生态模型和结构模型结合遇到的关键理论和技术问题:未能实现冠层微环境的精确模拟;物质分配和植株结构的结合研究还处于初步阶段;地上部分和根系耦合模拟还未实现.最后对该领域今后的研究趋势和内容进行了探讨:应基于形态结构模型进行冠层微环境的精确模拟;地上部分的物质分配可基于源-汇模型;地上部分和根系进行耦合模拟时,可将地上部分看作是"源",根据根系各部分的"汇强"模拟物质分配和根的生长.
