【摘要】 随着国家基础设施的大规模建设,铁矿资源丰富的山体被广泛开采,使得原有生境破坏,形成了数量巨大的无植被覆盖的裸露边坡。裸露边坡的形成对景观生态环境造成了极大的破坏,导致水土流失,严重者可能引起山体滑坡、坍塌。因此对裸露的边坡进行生态修复和生态治理已成为刻不容缓的问题。本试验研究区域位于山西省繁峙县境内铁矿开采背景区的铁矿场废弃地,经过几十年的开采,形成了大量的裸露陡坡和由剥离土堆积而成的缓坡,地形起伏较大;土壤母质暴露在外、氮素贫瘠,颗粒磷含量高,植被覆盖度低,水土流失相当严重。本文以矿区土壤、保水剂、速效肥及农家肥等作为喷播基质的原材料,选用L9(34)正交表进行配比以期达到促进紫花苜蓿和紫穗槐的最佳生长状态,为今后矿山废弃地采用喷薄绿化基质技术进行植被恢复直至生态恢复提供理论支持。

【Abstract】 With the large-scale construction of the country’s infrastructure,a large number of containing iron ore resource-rich mountain resources to be mined and destroyed the original habitat, the formation of a huge number of vegetation cover exposed slope.Bare slope formed on the landscape ecological environment caused great damage, leading to soil erosion, severe cases may cause landslides, collapse.The bare side slope ecological restoration has become imminent problems.The study area is located in FanShi city, Shanxi Province, background in iron ore mining area of mining abandoned land.Due to long-term exploration, has formed a large number of bare slope area.Due to the detachment of soil accumulation, form a gentle slope zone.Topographic relief is larger.Slope of soil parent material exposure.The soil phosphorus is higher, low nitrogen.Vegetation coverage is low, and soil erosion is serious.The phenomenon of soil and water loss is serious.In this paper, the soil water retention agent, quick-acting fertilizer and farmyard manure as raw materials of spray seeding matrix, using L9(34) orthogonal table ratio in order to promote the best growth status of Medicago sativa L and Amorpha fruticosa, for the future of mining wasteland by gushing greening substrate technology for vegetation restoration of ecological restoration to provide theoretical support.
