Abstract: The natural reserve of Ailao Mountain is located in the west-central part of Yunnan province. It is typically characterized by southern subtropical mountains. The vertical distribution of different soils is very clear. Analyses of soil samples indicate that the contents of soil organic matter and humic acid and the ratio of HA/FA are positively correlated with the altitude, but fulvic acid is in negative correlation.
