摘　　要：为解决干旱区露天矿排土场因水资源利用受限、植被恢复难度高、生物多样性丧失、土地污染等因素制约而导致的生态修复工作难问题,分析了干旱区排土场生态修复技术发展历程、研究现状、目前存在的问题以及土壤侵蚀机理研究、土壤重构改良技术、排土场植被种植技术、土壤微生物技术等生态修复核心技术,提出了“多模式、跨领域”、“因地制宜、因势利导”的生态修复新模式。In order to solve the difficult ecological restoration work of open-pit mine dump in arid areas,such as the limited utilization of water resources,high difficulty in vegetation restoration,loss of biodiversity,and land pollution,the article analyzes the development process,research status,and existing problems of ecological restoration technology for dump in arid areas,as well as the core ecological restoration technologies of soil erosion mechanism research,soil modification and improvement technology,soil vegetation planting technology and soil microbial technology,proposes a new ecological restoration model of"multi-mode,cross-field"and"according to local conditions and circumstances".
