We aim to understand the impact of ecological restoration on soil biogeochemistry, and the interrelationship between vegetation and soil phosphorus. In a study of two different‐aged soils in coastal New Zealand, soils are described along a transition from abandoned agricultural pasture, through 6‐year old restoration plots, towards forest fragments that have been largely undisturbed for 75 and 166 years. Soil biogeochemistry varied spatially along this restoration trajectory; there were profound changes in surface soil, but little impact on deeper soil horizons. In the early stages, soil organic matter accumulation and decomposition, and increasing demand of N from fast‐growing plants corresponded with rapid nutrient mineralization. Loss of soil total P, an increase of occluded P, and the increasing importance of soil organic P as soils weathered and aged, supported conceptual models of longer‐term soil pedogenesis. There was no evidence that the success of the establishment of plants varied across the site, but this is a first report of vegetation establishment during ecological restoration markedly impacting soil P dynamics and biogeochemistry.

新西兰沿海沙洲森林短期生态恢复轨迹上的土壤磷动态

我们旨在了解生态恢复对土壤生物地球化学的影响，以及植被与土壤磷之间的相互关系。在对新西兰沿海地区两种不同年龄土壤的研究中，描述了土壤从废弃的农业牧场到6年的恢复土地，过渡到在75和166年内基本上不受干扰的森林碎片。土壤生物地球化学沿该恢复轨迹在空间上变化。表层土壤发生了深刻的变化，但对更深层的土壤影响不大。在早期，土壤有机质的积累和分解以及速生植物对氮的需求增加与养分快速矿化有关。土壤总磷的损失，闭塞磷的增加，随着土壤风化和老化，土壤有机磷的重要性日益提高，这为长期土壤成岩作用的概念模型提供了支持。没有证据表明在整个地点建立植物的成功率各不相同，但这是关于生态恢复期间植被建立的首次报道，该研究显着影响了土壤磷的动力学和生物地球化学。
