摘　　要：旨在为作物耗水和碳水交换相关研究的模型选择提供理论指导,本研究归纳了气孔导度对单一和综合环境因子的响应情况;对现有气孔导度模型进行了分类和比较,包括基于Jarvis模型建立和改进的经验模型、基于BWB模型建立和改进的半经验模型、基于ABA调控建立和改进的模型、基于保卫细胞膨压控制理论建立和改进的模型;并概述了气孔导度模型在作物水分利用研究领域的应用,以叶片气孔导度和冠层导度的定量关系为切入点建立多尺度联合的机理模型将是未来作物耗水尺度拓展研究的热点。This review aims to provide theoretical references for model selection of crop water consumption and carbon-water exchange. The response of stomatal conductance to single and comprehensive environmental factors is summarized. The existing stomatal conductance models are classified and compared, including the empirical models constructed and improved based on Jarvis model, the semi-empirical models constructed and improved based on BWB model, the models constructed and improved based on ABA control and the models constructed and improved based on the guard cell swell control theory. The application of stomatal conductance model in crop water use research is also reviewed. The multi-scale joint mechanism model establishment with the entry point of the quantitative relationship between leaf stomatal conductance and canopy conductance will be the hotspots of future crop water consumption scale expansion research.
