Abstract Anthropogenic disturbances of soil environments predispose loss of soil ecosystem functions, including its habitat support function. In this study, the potential ecosystem support and habitat functions of soils from stockpiles and post-mining reclamation areas (ranging from 3 to 25 years) in two coal mining sites were assessed using Eisenia andrei bioassays. Endpoints such as avoidance response, mortality, relative growth rate and fecundity were determined. By taking into cognisance the ages of the reclamation areas, inference was drawn on the potential restoration of ecosystem support functions over the years since reclamation. Mortality and fecundity of earthworms did not suggest limited support functions of control and test soils. Net avoidance response (AR) indicated significant differences (P 80%. Earthworms generally preferred (P

使用蚯蚓（Eisenia andrei）生物测定评估南非煤矿土壤环境的生态系统支持功能

摘要 土壤环境的人为干扰易导致土壤生态系统功能的丧失，包括其栖息地支持功能。在这项研究中，使用 Eisenia andrei 生物测定法评估了来自两个煤矿区的库存和采矿后复垦区（范围为 3 至 25 年）的土壤的潜在生态系统支持和栖息地功能。确定了诸如回避反应、死亡率、相对增长率和繁殖力等终点。通过考虑填海区的年龄，推断填海后多年来生态系统支持功能的潜在恢复。蚯蚓的死亡率和繁殖力并未表明控制和试验土壤的支持功能有限。净回避反应 (AR) 表明存在显着差异 (P 80%。蚯蚓通常更受欢迎 (P
