| 摘 要： | 为了有效解决煤矸石山的生态恢复治理,采用径流小区观测法研究了风化煤矸石山水土流失变化特征及植被恢复,结果表明:裸露或植被稀少的矸石山边坡、林地边坡径流量分别与30 min雨强、45 min雨强最相关;沿坡长方向从上到下土壤抗冲指数呈现出先减小后增大的趋势;植物根系丰富,边坡比裸露边坡土壤抗冲性强;煤矸石山植被恢复成功的关键技术措施是细致整地、改良土壤,选择抗旱耐瘠薄植物种,确定适宜的栽植密度。研究成果为矿区废弃地有效治理提供了科学依据。

| Abstract: | In order to effectively improve the ecological restoration and management of coal gangue dumps,this study investigated the variation characteristics of soil and water loss at weathered coal gangue dumps by the means of runoff plot observation.The study shows that there are correlations between the runoff of bare coal gangue dump slope and 30min rainfall intensity,the runoff of forest land slope and 45min rainfall intensity.Soil anti-scouring index along slope downward direction presents a tendency of decrea... |
