Abstract: The relationship between the growth of three-year-old Eucalyptus urophylla in Shouning County, Fujian Province and different slope aspects, slope positions was studied in this article. Through comparative analysis, the result showed that: there was significant difference existing in growth of Eucalyptus urophylla among different slope aspects and different slope positions. Sunny slope could obviously promote Eucalyptus urophylla growth, with its middle and lower part was the most favorable for growth. The difference among different slope positions was also significant.

Key words: Eucalyptus urophylla, slope aspect, slope position, growth
