Forest management of boreal forests based on ecological processes related to disturbance regimes

本研究的目的是设备在北美和北方的北方森林的森林管理，基于生态过程相关的干扰制度。为了量化的扩散限制和环境过滤的影响，在加拿大的北方森林的再生过程中，我们制定了一个空间模型的非均匀的奈曼-斯科特过程，并检查火灾后的种子传播和再生网站的相对重要性，由于燃烧。结果表明，立地准备和保留制度的森林经营的重要性。为了了解在芬兰和俄罗斯的原始云杉冷杉为主的北方森林的影响，我们开发了一个圆形的统计模型，解释倒下的日志的方向。我们的研究结果表明，空间同步性和敏感性的森林对风的干扰。指出重建风蚀历史是发展生态林业的一条有效途径。

The aim of this study is to device forest managements in boreal forests of North America and Northern Europe, based on ecological processes related to disturbance regimes. In order to quantify dispersal limitation and environmental filtering effects on regeneration processes of boreal forests in Canada, we formulated a spatial model of the inhomogeneous Neyman-Scott process, and examined the relative importance of post-fire seed dispersal and regeneration site due to burning. The results suggested the importance of site-preparation and retention system for forest managements. To understand the impacts of windthrows on primeval Picea abies-dominated boreal forests in Finland and Russia, we developed a circular statistical model explaining directions of fallen logs. Our results demonstrated spatial synchronicity and the susceptibility of forests against wind disturbance. It was suggested that reconstructing windthrow history is a promising way for developing ecological forestry.
