The restoration of soil fauna on a spoil heap is a strong indicator of successful reclamation. The studies were conducted on two types of materials: bare rock (BR) and BR with topsoil (TS) which were applied during coal spoil reclamation and three vegetation types. Four variants investigated included natural forest succession on BR (Succession_BR) and TS (Succession_TS), afforestation (Reclamation_TS) and afforestation with Robinia pseudoacacia (Robinia_TS). Soil pH, soil organic carbon (SOC) and total nitrogen (TN) content, and soil texture were measured in 0–10 cm layers. Earthworms were collected using hand sorting method, and enchytraeids were collected using wet extraction with the heating method.

The investigated soil had varying pH values from 5.3 in a BR to 7.2 in Robinia_TS. The highest content of SOC and TN were in Successinon_BR, and the lowest was in Succession_TS. Enchytraeids density was in the following increasing order: 275, 2982, 3001 and 4548 ind m⁻² for Succession_BR, Robinia_TS, Succession_TS and Reclamation_TS, respectively. Earthworm density ranged from 0 ind. m⁻² in the Succession_BR through 116 ind m⁻² and 120 ind m⁻² in Reclamation_TS and Succession_TS, respectively up to 162 ind m⁻² in the Robinia_TS.

The reclamation treatment was a major driver for soil fauna development while vegetation type was of secondary importance. Investigated soil fauna was positively related to pH value and clay content. The most stimulating variant for the development of earthworms and enchytraeids was the application of reclamation with various tree species and the planting of Robinia pseudoacacia on the topsoil.

弃土堆上土壤动物群的恢复是复垦成功的有力标志。研究针对两种类型的材料进行：裸岩（BR）和带表土的 BR（TS）（在煤矿弃土复垦过程中使用）和三种植被类型。研究的四种变体包括 BR (Succession_BR) 和 TS (Succession_TS) 上的天然林演替、造林 (Reclamation_TS) 和刺槐造林 (Robinia_TS)。土壤 pH 值、土壤有机碳 (SOC) 和全氮 (TN) 含量以及土壤质地在 0-10 厘米层中进行测量。采用手工分选法收集蚯蚓，采用加热湿法提取法收集蚓螈。

所研究的土壤具有不同的 pH 值，从 BR 的 5.3 到刺槐_TS 的 7.2。SOC和TN含量最高的是Succession_BR，最低的是Succession_TS。Enchytraeids 密度按以下递增顺序：Succession_BR、Robinia_TS、Succession_TS 和 Reclamation_TS 分别为275、2982、3001 和 4548 ind m ^{-2 。}蚯蚓密度范围为 0 ind. Succession_BR中的m ^{-2到Reclamation_TS和Succession_TS中的116 ind m -2}和120 ind m ^-2，分别高达Robinia_TS中的162 ind m ^{-2 。}

复垦处理是土壤动物群发展的主要驱动力，而植被类型是次要的。调查的土壤动物与pH值和粘土含量呈正相关。对蚯蚓和蚓螈发育最刺激的变体是采用各种树种进行开垦并在表土上种植刺槐。
