摘　　要：利用Imaging-Pam脉冲调制荧光成像仪测定秦岭林区不同危害阶段的华山松离体针叶叶绿素荧光变化状况。结果发现Fm=0.139 7,F0=0.089 74,Fv/Fm=0.20,Fv/F0=0.349是华山松受害后的关键生理指标。Imaging-Pam chlorophyll fluorescence appliance were used to analyze the dynamic parameters of Dentroctonus arrnand in Qinling Mountains in the harm stage. The key physiological parameters to assess the harm stage of the pest were found as Fm=0.1397,F0=0.08974,Fv/Fm=0.20,Fv/F0=0.349.
