The canopy stomatal movement, a plant physiological process, generally occurs within leaves but its influence on exchange of CO2, water vapor, and sensible heat fluxes between atmosphere and terrestrial ecosystem. Many studies have documented that the interaction between leaf photosynthesis and canopy stomatal conductance is obvious. Thus, information on stomatal conductance is valuable in climate and ecosystem models. In current study, a newly developed model was adopted to calculate canopy stomatal conductance of winter wheat in Huang-Huai-Hai (H-H-H) Plain of China (31.5-42.7 degrees N, 110.0-123.0 degrees E). The remote sensing information from NOAA-AVHRR and meteorological observed data were used to estimate regional scale stomatal conductance distribution. Canopy stomatal conductance distribution pattern of winter wheat on March 18, 1997 was also presented. The developed canopy stomatal conductance model might be used to estimate canopy stomatal conductance in land surface schemes and seems can be acted as a boundary condition in regional climatic model runs.
冠层气孔运动是一种植物生理过程，通常发生在叶片内部，但其对大气与陆地生态系统之间二氧化碳、水汽和感热通量交换有影响。许多研究表明，叶片光合作用与冠层气孔导度之间的相互作用很明显。因此，气孔导度信息在气候和生态系统模型中很有价值。在当前研究中，采用了一种新开发的模型来计算中国黄淮海平原（北纬31.5 - 42.7度，东经110.0 - 123.0度）冬小麦的冠层气孔导度。利用来自NOAA - AVHRR的遥感信息和气象观测数据来估算区域尺度的气孔导度分布。还给出了1997年3月18日冬小麦冠层气孔导度分布格局。所开发的冠层气孔导度模型可用于估算陆面方案中的冠层气孔导度，似乎可作为区域气候模型运行中的一个边界条件。
