Although its economic importance, bauxite mining causes the loss of natural ecosystems. In this sense, the Technosols building from materials made or modified by man, such as mine tailings, is necessary for recovering degraded areas. Additionally, the Technosols management, such as subsoiling and liming, increases chances of plants establishment and growth. In this study, a degraded area by bauxite mining with constructed Technosol in the Eastern Amazon, Brazil, was tested under three different soil management treatments: Technosol-1 (Tech-1), Liming only; Technosol-2 (Tech-2), Subsoiling + 200 g of NPK in the pit; Technosol-3 (Tech-3), Scarification + liming + all Tech-2 procedures. In every treatment and in a reference forest (R-forest), 8 years after the initial seedling planting, three types of indicators were assessed: structural (horizontal vegetation structure, density of natural regeneration, and soil cover), compositional (species diversity, ecological groups, and dispersal syndromes), and functional (chemical properties of Technosols and dry matter and nutrients from the litter stock). The most representative species in all treatments were Croton matourensis and Vismia guianensis, both coming from the natural regeneration and common in early successional stages. Coverage rates in all treatments showed less than 5% of exposed Technosol and the diversity, ecological group, and dispersal syndrome indexes followed a successful trajectory along 8 years. Tech-2 and Tech-3 presented the best chemical attributes and nutrients in the litter stock, but they would probably last several decades to reach the R-forest attributes. Thus, subsoiling alone or with liming provided the best chemical results for soil, litter, and vegetation performance, being recommended to speed up restoration of degrades areas by bauxite mining in the Amazon.

铝土矿开采虽然具有经济重要性，但会造成自然生态系统的丧失。从这个意义上讲，用人为制造或修改的材料（例如矿山尾矿）建造的Technosols，对于恢复退化区域是必不可少的。此外，Technosols管理（例如深耕和撒石灰）增加了植物建立和生长的机会。在这项研究中，采用三种不同的土壤处理方法对巴西东部亚马逊地区利用人工合成的Technosol进行的铝土矿开采造成的退化地区进行了测试：Technosol-1（Tech-1），仅限黎明；Technosol-2（Tech-2），深坑+ 200 g NPK在坑中；Technosol-3（Tech-3），松土+石灰+所有Tech-2程序。在初始播种后的8年中，在每种处理方式和参照林（R林）中，评估了三种类型的指标：结构性（水平植被结构，自然更新密度和土壤覆盖率），组成性（物种多样性，生态群和扩散综合症）和功能性（Technosols的化学特性以及枯枝落叶中的干物质和养分）。所有处理中最具代表性的物种是巴豆成熟和巴豆（Vismia guianensis）均来自自然更新，且常见于演替初期。在所有治疗中，覆盖率均显示少于5％的Technosol暴露，并且多样性，生态组和传播综合症指数在8年内一直遵循着成功的轨迹。Tech-2和Tech-3提出了垫料中最好的化学属性和养分，但它们可能要持续数十年才能达到R-forest属性。因此，单独深浸或与石灰一起深浸可为土壤，垃圾和植被性能提供最佳的化学效果，建议通过亚马逊铝土矿开采来加速退化地区的恢复。
