从2004年和2005年美国佛罗里达飓风季节的高度影响县中随机抽取10%的社区样本，用于研究7场飓风的树木碎片生成和破坏。这些事件的木质碎片数量（立方米）（立方码; 1003）以及清理、树木移除和修剪的费率和成本。每30.5米（100英尺）街道段平均产生的碎片为0.59立方米（0.77立方英尺）（轻度损坏）、3.4立方米（4.44立方英尺）（中度损坏）和17.47立方米（22.85立方英尺）（高度损坏）;清除和处置费用平均为每立方米28.25美元（每立方英尺21.47美元）。大多数社区使用单位成本来计算树木移除和修剪率，平均分别为2%和28%的行道树。树木郁闭度、风速和城市开发用地比例对垃圾量均有显著影响。在2004年和2005年飓风季节，树木密度较大的佛罗里达社区产生的碎片数量减少。这些结果可用于帮助社区规划飓风管理活动，并估计对其树木资源的潜在损害。
A random 10% sample of communities in highly-impacted counties from the 2004 and 2005 Florida, U.S. hurricane seasons were used to study tree debris generation and damage from seven hurricanes. Woody debris amounts in cubic meters (m3) (cubic yards; yd3) as well as rates and costs for cleanup, tree removal and pruning were obtained for these events. Average debris generation per 30.5 m (100 ft) of street segment ranged from 0.59 m3 (0.77 yd3) for low damage, 3.4 m3 (4.44 yd3) for moderate damage, and 17.47 m3 (22.85 yd3) for high damage levels; cost of removal and disposal averaged $28.25 per m3 ($21.47 per yd3). Most communities used unit costing to account for tree removal and pruning rates, averaging 2% and 28% of street trees, respectively. Tree canopy, wind speed, and percentage of urban developed land all had a significant effect on debris amount. Florida communities with a greater tree density generated decreased amounts of debris during the 2004 and 2005 hurricane season. These results can be used to help communities plan for hurricane management activities and estimate potential damages to their tree resource.
