天然地形和人工沙棘风障对排土场平台植被恢复的影响
Impact of Wind-barrier of Natural Landform and Artificial Hippophae rhamnoides on Plants Restoration in Flat of Dumping Site
【摘要】 以霍林河露天煤矿为例 ,通过对排土场不同地段植被的观察、野外小区实验和室内分析的方法 ,调查研究了天然地形风障以及人工沙棘风障对半干旱地区露天煤矿排土场平台植被恢复状况的影响。研究结果表明 ,地形与人工沙棘风障不仅起到防风作用 ,还可以改善土壤理化性质 ,促进其它植物的生长 ,防治水土流失 ,加速排土场的植被恢复与生态重建的进程。
【Abstract】 The impact of wind barrier of natural landform and wind barrier of artificial Hippophae rhamnoides on the plants restoration in flat of dumping site of opencast coal mine in the semi arid was investigated through the observations on the plants in the different sectors of dumping site, field experiment and laboratory analysis. The Huolinhe opencast coal mine was taken as an example in this research. The results showed that wind barrier of natural landform and wind barrier of artificial Hippophae rhamnoides not only play a role of wind proofing, but also improve physical and chemical characters of the soil,accelerate the growth of other plants,reduce water erosion, speed up the processes of plant restoration and ecological rehabilitation in the dumping site.
