越来越多的证据表明，除了局部环境因素外，加速土地利用变化对景观层面因素的影响还能塑造土壤致病真菌多样性。然而，这些模式的全球代表性仍不明确。本研究，我们评估全球511个土壤样本中的致病真菌多样性如何响应景观因素，包括基于八项景观指标的景观复杂性指数，以及六个空间尺度（即从抽样坐标出发250米至10,000米半径的周边景观）。我们发现，虽然土壤变量解释了超过一半的变异，但致病真菌α多样性随景观复杂性和作物覆盖比例增加而增加，但随着草和树木覆盖比例减少，合计解释了总方差的23.4%。景观因素对β多样性的影响较弱，解释了13.0%的方差。在不同空间尺度上，草原生态系统对景观变量的响应比森林生态系统更强烈。景观因素对根相关真菌的相对贡献高于叶片/果实/种子相关真菌。我们的结果强调了局部因素的重要性以及景观模式在塑造全球土壤致病真菌分布中的互补作用，强调了生态系统和真菌功能群中尺度依赖效应。
原文摘要（English）
Growing evidence has shown that, apart from local environmental factors, changes in landscape-level factors by accelerated land-use change can also shape soil pathogenic fungal diversity. However, the global representativeness of such patterns remains unclear. Here, we assess how pathogenic fungal diversity in 511 soil samples worldwide responds to landscape factors, including landscape complexity index based on eight landscape metrics and quantity of different land cover types across six spatial scales (i.e., surrounding landscape, 250 m to 10,000 m radii from the sampling coordinate). We find that while soil variables explain over half of the variance, pathogenic fungal alpha diversity increases with landscape complexity and crop cover proportion, but decreases with grass and tree cover proportion, together explaining 23.4% of the total variance. Landscape factors have weaker impacts on beta diversity, explaining 13.0% of the variance. Across spatial scales, grassland ecosystems exhibit increasingly stronger responses to landscape variables compared to forest ecosystems. Landscape factors have a higher relative contribution to root-associated fungi than leaf/fruit/seed-associated fungi. Our results emphasize the importance of local factors and the complementary role of landscape patterns in shaping global soil pathogenic fungal distributions, highlighting scale-dependent effects across ecosystems and fungal functional groups.
