【摘要】 为加速高盐胁迫下芒硝盐岩弃渣场植被生态修复，选取骄子山隧洞弃渣场及其周围环境区作为研究区，采用样地抽样调查法，从优势物种、群落结构、生物量、生物多样性等方面进行对比分析。结果表明：弃渣场土壤pH值为8.51～9.26,可溶性盐质量比在5.12 g/kg～38.45 g/kg之间，属高盐弱碱性土壤环境；弃渣场共发现植物17种，隶属9科16属，以草本植物为主，占总物种数的76.47%;弃渣场区植被生态修复以豆科、禾本科、菊科植物为主，占总物种数的64.71%;单位面积生物量和物种丰富度指数最大试验区均为有覆膜阻断客土区。试提出以构树+银合欢+草木樨+类芦+龙舌兰+葛为主的乔灌草植被配置模式进行植被生态修复。更多还原

【Abstract】 In order to accelerate the vegetation ecological restoration in a Glauber’s salt slag dump under high salt stress, Jiaozishan tunnel waste dump and its surrounding environment area were selected as the study area, the dominant species, community structure, biomass and biodiversity were compared and analyzed by sampling survey. The results showed that the pH value of the soil in the slag dump was 8.51 ～ 9.26, the mass ratio of soluble salt was 5.12 g/kg ～ 38.45 g/kg, belonging to a high salt and weak alkaline environment. There were 17 species of plants found in the slag dump, belonging to 9 families and 16 genera, mainly herbaceous plants, accounting for 76.47% of the total species. The vegetation ecological restoration in the slag dump was dominated by Legumes, Gramineae and Compositae, accounting for 64.71% of the total species. The test area with the largest biomass per unit area and species richness index was the guest soil area blocked by mulching. This paper tries to put forward the arbor-shrub-grass vegetation configuration mode of Broussonetia papyrifera(Linnaeus) L’Heritier.+ Leucaena leucocephala(Lam.) de Wit.+ Melilotus officinalis(L.) Pall.+ Neyraudia reynaudiana(Kunth)Keng.+ Agave americana L.+ Pueraria lobata(Willd.) Ohwi. for vegetation ecological restoration.更多还原
