植被冠层尺度生理生态模型的研究进展

随着人们对植物生命活动各个过程研究的不断深入,以植物生理过程、物理过程为基础的各种生理生态学模型逐渐发展起来,而植被冠层尺度生理生态学过程模型已成为生态系统模型的核心之一。目前植被冠层尺度的大叶模型、多层模型、二叶模型以其成熟的理论基础及对植被冠层的光合作用、蒸腾作用较为成功的模拟,得到了广泛的应用。3个模型都以光合作用-气孔导度-蒸腾作用耦合模型为基础,但又具有各自的特点。本文对3种模型的结构及特点进行了总结,并对其进行了比较,简要介绍了目前植被冠层尺度生理生态学模型的应用及存在的问题和发展状况。

Research advances in eco-physiological model of plant canopy scale

With the deepening of plant life research,different eco-physiological models based on plant physiological and physical processes are developed step by step,and the eco-physiological model of plant canopy scale becomes one of the cores of ecosystem model.At present,big-leaf model,multilayer model,and two-leaf model of plant canopy scale are widely used,because these three models have ripe theoretical base,and successfully simulated the photosynthesis and transpiration of plant canopy.These models are all based on the model which combined photosynthesis,stomatal conductance and transpiration,and have their own characters.This paper introduced and compared the structures and characters of the three models,and discussed their applications,shortcomings,and development trends.
