Abstract: Based on the field investigations,laboratory examinations and statistical analysis,the results showed,that the altitude and the slope aspect had no significant effect on the distribution of Dolichomitriopsis diversiformis (Mitt.) Nog.) in its distributive area in Fanjing Mountain,that the distribution of D.diversiformis on the upper parts,middle parts and lower parts of five host tree trunks had positive correlation with the bark water content of the corresponding parts(r was 0.75,0.74,0.82,0.44,0.15 respectively) and that the distribution of D.diversiformis on the sides of near ground and far groud in different degree inclined tree trunks had positive correlation with the bark water content in the near ground tree barks and far ground barks.The water content of tree barks was the main factor that influenced the distribution of D.diversiformis.The other ecological factors that influenced the distribution of D.diversiformis were also analyzed and summarized.

Key words: Dolichomitriopsis diversiformis (Mitt.) Nog., epiphytic moss, distribution, environment
