摘　　要：排岩场是矿山废弃地中生态退化最严重的类型,针对铁矿排岩场砾石裸露、土壤缺少的恶劣环境条件,以冀东地区铁矿排岩场为研究材料,开展了鱼鳞坑、客土和裸根苗直接装容器杯的综合造林试验。结果表明,采用规格18cm×14cm的塑料容器杯直接装容器杯造林,丁香和爬山虎成活和生长情况较好,成活率分别为82%和97%,造林效果理想;刺槐采用26cm×21cm的大规格容器杯造林,成活率仅达60%,造林效果较差。According to the environment ot excessive gravels anti absent soil in iron mine dump,the afforestation technology was studied in eastern Hebei Province. The test of fish-scale pits, carrying soil and temporary container seedling were developed. It showed that survival and growth were better which of Syringa oblata and Parthenoeissus orlcuspidata which were grew into plastic container of 18 cm x 14 era. The afforestation survival rate were 82% and 97%. The afforestation survival rate of Robinia pseudoacacia was only 60%, which was grew into plastic container of 26 cmx 21 cm. The Syringa oblata and Parthenocissus oricuspidata had better effect than Robinia pseudoacacia.
