Plants' physiological characteristics as well as environmental aspect determine their capacity to resist and absorb hydrogen fluoride. To study the effects of hydrogen fluoride on the physiology of five species of Euphorbiacea seedlings, we, in this study, simulated hydrogen fluoride contamination with the fumigation method with a view to measure and comprehensively evaluate chlorophyll fluorescence parameters and cell membrane permeability. The findings showed that, in an environment with concentrated and fumigated hydrogen fluoride, plants could regulate to resist hydrogen fluoride contamination, but they might be damaged once the threshold is exceeded. And there is difference in individual plants. Five native Euphorbiaceae tree species were damaged in fumigation. According to the comprehensive evaluation, Vernicia montana and Endospermum chinense, which resisted hydrogen fluoride better than other three kinds of plants, were viewed as the first-choice tree species in the atmospheric environment contaminated by hydrogen fluoride. Other tree species were also considerable resistant tree species.
