摘要：
Fast growing and short-rotation tree crops provide unique opportunities to reclaim phosphate-mined lands in central Florida. Optimum management of the eucalyptus short-rotation woody crop forestry system studied necessitates harvests every 2.5-3.6 years and replanting after 2-5 coppice harvests. The value of phosphate mined land under Eucalyptus amplifolia forestry ranges from $762 to $6507 ha(-1) assuming discount rates of 10% and 4%, respectively, establishment costs of $1800 ha(-1), planting costs of $1200 ha(-1), planting density of 8400 tree ha(-1), and a stumpage price of $20 dry Mg-1.
