摘 要 ：本文据同步观测到的气孔阻力和土壤水势、净辐射能、气温、叶温、水汽压、饱和差、风速等环境因素变化值，用统计方法分析了小麦叶片气孔阻力与环境因素的关系，结果表明：冬小麦叶片的气孔导性主要受土壤水势影响。叶片正反两面的气孔对环境因素变化的反应不同，正面气孔导性主要受土壤水势影响，而反面气孔导性则与气温、水汽压和饱和差关系较大。

Abstract:This paper gives the results of wheat stomatal resistance influenced by environmental factors. The analysis method used is multiple regression. The results explain that: soil water potential in the root zone is the major factor that influences stomatal resistance. The effect of environmental factors to abaxial stomata and adaxial stomata are different: the abaxial stomatal resistance is mainly influenced by soil water potential, but the adaxial stomatal resistance is mainly influenced by air temperature and air humidity.
