中文摘要：为建立抗风性强的林分空间优化模式提供理论依据,以广东湛江麻章区湖光岩玛珥湖风景区4个典型样方的台湾相思林分为研究对象,对强台风干扰前后林分空间结构的各种指标进行调查分析。结果表明:强台风可影响树种混交度Mi、健康指数Hi、大小比指数Ui、竞争指数Ci、角度尺Wi和空间密度指数Di;6个指标中,影响最大的是混交度Mi;长期的强台风干扰可促进台湾相思林的演替;台风影响下林分空间结构的不断改变促进了抗风性优良的本土树种的成长,其林分的抗风性能不断提高。表明改变森林群落的空间结构能导致其功能转变,通过改善台湾相思林分空间结构,可增强其林分的抗风功能。

外文摘要：The 4 typical samples of the Acacia confusa forest stands in Huguangyan Ma’ar Lake Scenic Area,Zhanjiang,Guangdong were investigated to study their various indicators of their spatial structure after a strong typhoon disturbance.The findings indicated： Strong typhoons can affect their mingling Mi,Health index Hi,Neighborhood comparison Ui,competition index Ci,neighborhood pattern Wi and spatial density index Di,and the greatest influential indicator is mingling Miamong 6 indicators.The long term strong typhoon disturbance can accelerate the Acacia confusa forest succession.The changing spatial structure under typhoon influence can promote the growth of local wind resistant tree species,and the stand wind resistance would increase continuously.As such,the result showed that changes of spatial structure of the forest would lead to its functional changes,and optimal changes in its spatial structure can enhance the Acacia confusa forest wind resistance function.
