摘　　要：排土场生态重建是采矿迹地生态重建的重要组成部分。为了尽快恢复排土场植被,改善矿区生态环境,马兰庄铁矿采用工程复垦与生物复垦相结合的措施,初步建立了人工林生态系统。根据马兰庄铁矿排土场的生态破坏类型,采取排土场覆土生态重建的模式,对排土场进行分区治理,选取试验基地进行植被恢复与生态重建试验。根据所选植物的生长状况,筛选出刺槐、紫穗槐、连翘、火炬树、沙棘等适宜于排土场立地条件的先锋植物和适宜树种。The ecological rehabilitation of refuse dump is important for abandoned mine land. In order to restore vegetation and improve ecological environment of mining dump, the measures of organism reclamation and engineering reclama- tion were adopted in Malanzhuang iron mine, and the plantation ecology system was preliminarily established. According to the ecological damage of Malanzhuang iron mine, the mode of ecological reconstruction was made. The dump was divided in- to different parts, one of which is selected as test base of vegetation restoration and reconstruction experiments. According to the ecological conditions of the selected plants, the pioneer plants and appropriate trees are chosen as the suitable plants based on dump site conditions, such as robinia pseudoacacia, amorpha frutieosa, forsythia suspensa, rhus typhina, hippophae rhamnoides etc.
