森林土壤养分有效性的干扰的演替轨迹和影响是什么？答案仍然难以捉摸，因为感兴趣的时间尺度很长，而且影响土壤特性的因素有很多。我们在美国密歇根州北部的一个具有区域代表性的景观中回答这个问题。晚演替的参考资料放在一边，该景观上的大多数森林在 1870 年至 1911 年间被砍伐和烧毁；随后，由两个时间序列组成的林分要么被砍伐并再次焚烧，要么仅以数十年的间隔被砍伐。在 A、B 和 C 层中可以检测到干扰和演替的影响，特别是受灰烬沉积影响的特性：pH、Ca 和 Mg 随着年龄的增长而下降，但在两次燃烧的林分中较高。两次燃烧的地平线 NH4+ 低于一次燃烧的林分，并且在两种时间序列中都随着年龄的增长而下降。 B层Fe在两个时间序列中都随着年龄的增长而增加，但在两次烧毁的林分中仍然较低，这表明在更严重的干扰后成土恢复的速度较慢。与 A 层和 B 层相比，土壤性质由扰动和演替驱动，而 C 层中的结构影响通过钙、镁、钾、铝和阳离子交换能力的变化而明显受到影响。总的来说，这些结果表明了景观水平上深层、持久的干扰影响和母质的自下而上的影响。
What are the successional trajectories and impacts of disturbances on forest soil nutrient availability? Answers remain elusive because the time scale of interest is long and many factors affect soil properties. We address this question on a regionally representative landscape in northern Michigan, U.S.A. Late-successional reference stands aside, most forests on this landscape were clearcut and burned between 1870 and 1911; subsequently, stands comprising two chronosequences were either cut and burned again, or cut only, at multidecadal intervals. Influences of disturbance and succession were detectable in A, B, and C horizons, particularly for properties affected by ash deposition: pH, Ca, and Mg declined with age but were higher in twice-burned stands. A horizon NH4+was lower in twice-burned than once-burned stands and declined with age in both chronosequences. B horizon Fe increased with age in both chronosequences but remained lower in twice-burned stands, suggesting slower recovery of pedogenesis following more severe disturbance. Contrasted against A and B horizons, where soil properties were driven by disturbance and succession, textural influences were evident in C horizons through variation in Ca, Mg, K, Al, and cation exchange capacity. Collectively, these results indicate deep, long-lasting disturbance impacts and a bottom-up influence of parent material at the landscape level.
