本文利用１９９２年黑河ＢＩＯＰ（生物气象加强观测）期间光合作用综合分析仪在田间测定的资料，分析了干旱区春小麦单叶片气孔导度、光合速率和蒸腾强度的日变化及环境因子的影响。分析结果表明；光合作用和蒸腾强度与太阳辐射、环境温度、水汽压差及土壤湿度等主要环境因子的影响密切相关。同时，我们根据Ｊａｒｖｉｓ的理论发展了光合有效辐射、环境温度和水汽压差对气孔导度影响的半经验模型，根据此气孔运动综合模型建立了春小麦单叶片蒸腾强度的计算模型，分析了诸环境因子对蒸腾强度的影响程度，并将模型计算值与Ｐｅｎｍａｎ－Ｍｏｎｔｅｉｔｈ公式的计算值和实际观测值进行了比较
In this paper, the data of field photosynthesis in comprehensive analysis of photosynthesis during the BIOP (bio-meteorological observation) in 1992 were used to analyze the diurnal variation of stomatal conductance, photosynthetic rate and transpiration intensity of spring wheat leaves and the influence of environmental factors. The results show that photosynthesis and transpiration intensity are closely related to the influence of major environmental factors such as solar radiation, ambient temperature, water vapor pressure and soil moisture. At the same time, according to the theory of Jarvis, we developed a semi-empirical model of the effect of photosynthetically active radiation, ambient temperature and water vapor pressure on stomatal conductance. Based on this stomatal movement model, we established a computational model of spring wheat single leaf transpiration intensity, Factor on the impact of transpiration strength, and the calculated model and Penman-Monteith formula calculated values and the actual observations were compared
