飓风被认为是许多热带森林结构和组成的最重要决定因素之一。在金塔纳罗奥，这些自然现象是森林自然动态的一部分。飓风迪安是2007年8月21日发生的最新天气事件之一，影响了大约90万公顷的半常绿森林。对植被遭受的损害进行了量化，并讨论了受飓风迪安影响的森林物种组成和结构的变化。结果发现，森林的组成没有受到影响。飓风对森林结构的影响最大。林下树木受害程度高于林冠树木。危害类型以中小分支危害、连根拔起和折断为主。森林管理可能增加了这片森林对风害的敏感性。本文根据文献资料和野外取样的观察结果，讨论了森林经营对森林敏感性的影响。建议减少伐木活动中“木材集中”的次数，并将砍伐受损树木纳入管理计划。还提议监测飓风对森林的破坏和未破坏的长期动态。
Hurricanes are considered among the most important determinants of the structure and composition of many tropical forests. In Quintana Roo, these natural phenomena are part of the natural dynamics of the forest. Hurricane Dean, on of the most recent of these weather events occurred on August 21, 2007, affecting around 900,000 ha of medium semi-evergreen forest. The damage occurred on the vegetation was quantified and changes in species composition and structure of the forest affected by Hurricane Dean were discussed. It was found that the composition of the forest was not affected. The greatest effect of the hurricane was on the forest structure. Understory trees was more damaged that canopy trees. The main types of damage were the small and medium branch damage, uprooted and snapped trees. Forest management could have increase the susceptibility of this forest to wind damage. The effects of forest management in the susceptibility of the forest are discussed based on bibliographic information and some observations during field sampling. It is proposed to reduce the number of “wood concentration” during logging activity, as well as to incorporate to management plans, the extraction of damaged trees. It is also proposed to monitor the long-term dynamics both of damaged and undamaged forest by hurricanes.
