摘要
排土场存在的严重水土流失,是草原区露天煤矿水土保持和生态恢复的关键。通过对排土场植被重建情况的调查与不同覆盖度下水土流失特征的分析,得出植物群落特征可较好的反映排土场生态恢复与重建的生态效益,对未进行人为覆土植被恢复的排土场,其自然恢复植被的过程是比较漫长的。
The serious soil and water loss existing dump , province is open coal mine water and soil conservation and ecological recovery of the key. Through to the dump vegetation survey of reconstruction with different coverage under the analysis of characteristics of the soil and water loss, reach a conclusion that plant community characteristics may be better reflect dump ecological restoration and reconstruction of the ecological benefit, not for human turns the soil of vegetation restoration dump, its natural vegetation recovery process is pretty long.
