AbstractTo explore effectiveapproaches for pine forest transformation，a row mixed afforestation experiment （ratio 2：1）wasconducted in the clear-cut areas of Pinus elliotii in the low mountains and hills of Dongshan County， where Casuarina equisetifolia was interplanted with Acacia cincinnata ，Acacia crassicarpa，and Acacia auriculiformis respectively.Analysisof the1O-year-old experimental forests showed that Casuarina equisetifolia，Acacia crassicarpa，and Acacia cincimmata had high survival rates and rapid growth. The mixed forests of Casuarina equisetifolia + Acacia crassicarpa and Casuarina equisetifolia + Acacia cincinnata exhibited high soil aeration，large porosity，lowbulkdensity，andhighsoilfertility.For pineforesttransformation inthelowmountainsand hils，mixedafforestation of Casuarina equisetifolia with Acacia crassicarpa or Acacia cincinnata is recommended.
