摘　　要：我国辽西地区矿产储量巨大,对矿产的大量开采导致矿区大面积的土地遭到破坏,植被减少。辽西地区处于半干旱地带,常年降水量低,再加上常年的开采,矿区的植被恢复工作极其困难。针对辽西半干旱地区冬季寒冷、降水量低,且矿区内石砾多、土壤少、保水性能差、植被生存条件刻薄状况,提出应挑选廉价经济的土壤以及适宜的植物用作矿山植被恢复。The western Liaoning of China has huge reserves of mines,due to the indiscriminate mining of minerals,large areas of land in the mining area have been destroyed and vegetation has been reduced.The western Liaoning is a semi-arid area,with low precipitation all year round,and it is even more difficult to restore vegetation in the mining area.In view of the cold winter,low precipitation,more gravel,less soil,poor water retention performance and harsh vegetation living conditions in the semi-arid area of western Liaoning Province,cheap and economic soil and suitable plants should be selected for mine vegetation restoration.
