摘　　要：分别利用便携式叶绿素测定仪(SPAD-502Plus)和L1-6400便携式气孔导度系统对岷江百合的叶绿素含量和气孔导度进行测量,用统计软件SPSS 19.0进行非参数检验,结果表明:1)通化沟岷江百合不同植株个体之间叶片叶绿素含量和气孔导度无显著差异;龙溪沟和面朝沟的岷江百合不同植株个体之间叶片叶绿素含量差异显著,而其气孔导度则没有表现出显著的差异。2)通化沟、龙溪沟、面朝沟3个不同生境的岷江百合个体之间叶片叶绿素含量和气孔导度的差异都极显著。The stomatal conductance and leaf chlorophyll concentration of Lilium regale were measured by using a chlorophyll meter（ SPAD -502 Plus） and a stomatal conductance system （Li -6400） ; and then the nonparametric test of the SPSS19.0 was carried out. The results were obtained as follows： （ 1 ） Differ- ences in the stomatal conductance and the leaf chlorophyll concentration in Tonghuagou were not remarka- ble. Leaf chlorophyll concentration of Lilium regale in Mianchaogou and Longxigou were striking, but dis- similarities in the stomatal conductance were inconspicuous. （2） The differences in the stomatal conduct- ance and leaf chlorophyll concentration in such three habitats as Tonghuagou, Longxigou and Mianchaogou were extremely obvious.
