摘要
生态脆弱的寒区在粗放的矿产资源开发方式下,土壤和植被等生境的破坏导致生物多样性退化甚至丧失,引起环境系统结构和功能的变异。位于寒区的内蒙古满洲里扎赉诺尔矿区属于环境敏感的典型地区之一。通过对煤矿区地质灾害治理、生态环境恢复和国家矿山公园建设等,开展土壤基质处理、草种筛选、栽培技术、混播筛选、喷播技术、推广示范等方面集成试验示范研究,从而集成得出:"大播量+重施肥+禾草混播+加盖无纺布"是寒区露天煤矿生态修复取得成功的关键技术。
Under the extensive exploitation of mineral resources in ecologically fragile cold regions,the destruction of habitats such as soil and vegetation lead to the degradation or even loss of biodiversity,resulting in the variation of the structure and function of the environmental system.The Zhalainuoer mining area in Manzhouli city,Inner Mongolia,located in the cold region,is one of the typical environmentally sensitive areas.Through the measures of geological disaster administer,ecological environment restoration and national mine park construction,the integrated experimental demonstration research on soil matrix treatment,grass seed selection,cultivation technology,mixed sowing selection,spray sowing technology and promotion demonstration were carried out,and it was concluded that"large amount of sowing + heavy fertilizer + grass mixed sowing + non-woven covering"is the key to the success of ecological restoration in the cold area open-pit coal mine key technology.
