Taking Hainan Eucalyptus plantation as the research object with 4 other kinds of plantations or natural forest as reference plots, the effects of different forest land types on soil nutrient contents were analyzed, and the differences of soil properties were discussed. The results showed that: (1) Eucalyptus plantations were relatively helpful to reduce soil bulk density and enhance the stability of water-stable aggregates; (2) Eucalyptus plantations can improve the content of soil organic matter; (3) Soil pH showed an overall acidiifcation trend under forest land conditions in Hainan; total n...
