摘要

城市中的自然绿地容易因高水平的娱乐使用和踩踏引起的磨损而退化。本研究的目的是将北方城市森林的磨损量（路径和磨损地面）与景观尺度和局部尺度的预测因子联系起来，以帮助评估与城市密度相关的风险。在芬兰南部三个城市中心的73个森林中测量了磨损，并分析了与周围居住密度、附近森林面积和当地森林特征的关系。中位数观察到的磨损覆盖率为12%，而最受影响的部位磨损超过90%。较高的居住密度和较小的森林面积对磨损有独立的加剧作用。磨损也与树木结构有关，在森林内部比在边缘更大。我们的研究结果表明，发展中城市的景观变化可能转化为城市森林生态退化的风险。

Research note: Surrounding landscape and local tree structure explain wear in boreal urban forests

Natural urban green areas in cities are susceptible to degradation due to high levels of recreational use and trampling induced wear. The aim of this study was to relate the amount of wear (paths and worn ground) in boreal urban forests to landscape-scale and local-scale predictors to help assess risks associated with urban densification. Wear was measured in 73 forests in three urban centers in southern Finland and analyzed in relation to surrounding residential density, amount of nearby forest area, and local forest characteristics. Median observed worn cover was 12 % while the most affected sites were over 90 % worn. Higher residential density and smaller forest area had independent exacerbating effects on wear. Wear was also related to tree structure and tended to be larger in forest interiors than near the edge. Our findings showcase how landscape transformations in growing cities may translate into risks of ecological degradation in urban forests.

期刊介绍： Landscape and Urban Planning is an international journal that aims to enhance our understanding of landscapes and promote sustainable solutions for landscape change. The journal focuses on landscapes as complex social-ecological systems that encompass various spatial and temporal dimensions. These landscapes possess aesthetic, natural, and cultural qualities that are valued by individuals in different ways, leading to actions that alter the landscape. With increasing urbanization and the need for ecological and cultural sensitivity at various scales, a multidisciplinary approach is necessary to comprehend and align social and ecological values for landscape sustainability. The journal believes that combining landscape science with planning and design can yield positive outcomes for both people and nature.
