Abstract

In managed European hemiboreal forests, windstorms have a notable ecological and socioeconomic impact. In this study, stand properties affecting windstorm damage occurrence at the stand-level were assessed using a Generalized Linear Mixed model. After 2005 windstorm, 5959 stands dominated by birch (Betula spp.), Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies (L.) Karst.), with mean height > 10 m were inventoried. Windstorm damage was positively associated with spruce and pine-dominated stands, increasing mean height, fresh forest edges, decreasing time since the last thinning and stronger wind gusts. Tree species composition – mixed or monodominant – was not statistically significant in the model; while, the admixture of spruce in the canopy layer was positively associated with higher windstorm damage. Stands on peat soils were more damaged than stands on mineral soils. Birch stands were more damaged than pine stands. This information could be used in forest management planning, selection of silvicultural treatments to increase forest resilience to natural disturbances.

拉脱维亚半北方森林林分水平影响风暴破坏的因素:2005年冬季风暴案例研究

在管理的欧洲半北方森林中，风暴具有显著的生态和社会经济影响。本研究采用广义线性混合模型，对林分特性对林分水平风暴灾害发生的影响进行了评估。2005年风暴过后，5959个林分以桦树(Betula spp.)、苏格兰松(Pinus sylvestris L.)和挪威云杉(Picea abies (L.))为主。喀斯特)，平均高度bbb10 m。风暴灾害与云杉和松林为主的林分、平均高度增加、林缘新鲜、间伐时间缩短和阵风增强呈正相关。树种组成(混合或单优势)在模型中无统计学意义;而云杉在林冠层的掺加与较高的风害呈正相关。泥炭土壤林分比矿质土壤林分受损更严重。桦树林比松木林受损更严重。这些信息可用于森林管理规划，选择造林措施，以提高森林对自然干扰的恢复能力。
