%X Six woody plant species from Beijing mountain zone were surveyed for the foliar stomatal conductance under different light conditions,guard cell length,open stomatal apertures,and surface characteristics with scanning electron microscopy.All plant's stomata are distributed on the abaxial of leaves.The stomata density is Quercus liaotungensis>Prunus armeniaca var. ansu > Syringa pekingensis > Juglans mandshurica > Fraxinus rhychophlla .Statistics analysis result showed that there is a great difference among them.And their foliar surface have difference in microfeatures. Same plant,under different habits,has different stomatal density and conductance.Under sunshine, Prunus armeniaca var .ansu,Vitex negundo var. Rhynchgensis and Syringa pekingensis have the lowest stomatal conductance,then, Quercus liaotungensis and Fraxinus rhychophlla follow, and Juglans mandshurica has the highest.Under shade conditions, Fraxinus rhychophlla, Syringa pekingensis and Juglans mandshurica have relatively high stomatal conductance,especially at noon.
