2008年初，一场突如其来的冰暴袭击我国南方，严重影响了亚热带森林生态系统。利用增强植被指数（EVI）的中分辨率成像光谱仪产品，结合实地调查资料，分析鄱阳湖流域森林破坏的空间格局。结果表明，迎风面和海拔400- 1, 000 m的森林对冰暴敏感;从地形遮挡效应的角度可以了解冰暴后森林受害的空间格局。由于盆地内的山脉阻挡了冷流和风，迎风面的危害比其他面严重，这与北美以往的研究结果相似。最严重的冠层损失超过63%（EVI损失0.085）发生在海拔400-800 m的区域.第二次严重的森林破坏发生在海拔800- 1，500米的地区，树冠损失33%（EVI损失0.035），这与北美以前的研究不同，该研究发现这些海拔高度的损害迅速减少。这一观察结果符合生态干扰理论，表明冰暴在受冰干扰事件影响较少的森林中造成更大的损害。与温带地区相比，亚热带森林与冰暴有关的森林损害模式似乎更为广泛。这意味着亚热带森林比温带森林更容易受到冰暴干扰。
In early 2008, an unexpected ice storm hits southern China, severely affected the subtropical forest ecosystems. We used the moderate resolution imaging spectroradiometer products of Enhanced Vegetation Index (EVI) corroborated with information gathered from field investigations to analyze the spatial patterns of forest damage in Poyang Lake Basin. The results showed that forests on windward aspects and 400–1,000 m elevation zones are sensitive to ice storm. The spatial pattern of forest damage after the ice storm can be understood in light of topographical sheltering effect. Due to the mountains of the basin blocked the cold flow and wind, the damage on windward aspects showed more severity than other aspects, which was similar like previous studies in North America. The most severe canopy loss beyond 63 % (EVI loss 0.085) occurring on 400–800 m elevation zones. The secondary severe forest damage was on 800–1,500 m elevation zones with canopy loss 33 % (EVI loss 0.035), which unlike previous studies in North American that found damage was rapidly decreased at these elevations. This observation fits the ecological disturbances theory suggests that ice storms generating greater damage in forests which less frequently impacted by ice disturbance events. There appears to be a broader pattern of forest damage associated with ice storm in subtropical forests than in temperate regions. This implies that the subtropical forests are more vulnerable than temperate forests to ice storm disturbance.
