矸石废弃地栽植金银花的绿化可行性分析

Feasibility Analysis on Honeysuckle Applied to Vegetation of Coal Rejects Dumping Ground

在梯田整地法应用栽植模式下,采用野外调查取样结合室内分析测试方法,调查研究金银花栽植的门头沟矸石废弃地土壤基本性状及金银花的生长情况。结果表明:矸石废弃地表层土壤水分含量较低,不存在盐化、酸化危害,土壤养分状况整体处于适宜、较适宜水平,金银花对N、P养分的吸收量较大;金银花长势良好,成活率高,生长速度快,能够快速覆盖地表;金银花地植被种类由2010年11种增加至2011年17种,且增加2种本木植物,生态群落植被演替进程较快,初步形成了10余种伴生物种的灌木层、草本层生态群落,生态修复效果良好。研究表明金银花可用于矸石废弃地的绿化。

Under the application of the terraced field soil preparation method to the planting mode,an outdoor investigation and sampling combined with indoor analysis and measurement method was applied to investigate and study the soil basic features of the Mentougou coal rejects dumping ground for the honeysuckle planting and the honeysuckle growing conditions.The results showed that the moisture content of the surface soil on the coal rejects dumping ground was low and there was no salt content and acidification damages in the surface soil.The overall soil nutrient status was in a suitable or less suitable level.The honeysuckle would have a high absorption value of the N and P nutrients.The honeysuckle would grow well,have a high survival rate and a fast growing speed,and could be quickly covered the surface ground.From 2010 to 2011,the species of the honeysuckle for the vegetation was increased from 11 to 17 with additional two woody plants.The vegetation of the ecological community was evolved and replaced quickly.There were over 10 accompanying species of the shrub and herb ecological communities formed initially.The ecological restoration effect was good.The study showed that the application of honeysuckle to the afforestation of the coal rejects dumping ground would be feasible.
