摘　　要：通过运用植物样方调查方法和人工种植试验,调查位于毛乌素沙地范围内的哈拉沟煤矿开采塌陷区地上植被,以植物群落理论对植被恢复进程进行对比分析,并进一步评价和探讨人工干预对当地植被恢复的积极作用。结果表明:植被自然恢复和人工干扰恢复均可以短时期内达到很高的植被覆盖度,但植物群落结构及其稳定性差异较大,适当给予人工正向干扰有利于这类地区植被环境的快速修复,合理的植物群落结构配置可缩短矿区生态恢复进程。The telluric vegetation in coal mining subsidence regions within the range of Mu Us Desert was investigated utilizing vegetation quadrat investigation method and artificial cultivation test. Comparison and analysis was done on the recovery process of vegetation using phytocoenosium theory, to further evaluate and discuss the positive effects of manual intervention on the recovery of local vegetation. The result show that, both natural recovery of vegetation and manual intervention can realize very high vegetation cover degree in a short time, but the structure and stability of phytocoenosium differs a lot. Proper positive manual intervention is beneficial to the recovery of vegetation environment in this kind of regions and mine ecological restoration can be shortened with reasonable phytocoenosium structure configuration.
