矿山废弃地生态恢复基质改良研究

AMELIORATION OF SOIL MEDIA DURING ECOLOGICAL RESTORATION IN THE MINING WASTELAND

矿业废弃地破坏和侵占了大量土地资源, 因此这些废弃地的生态恢复成为目前世界尤其是中国急需解决的问题。矿业废弃地的基质改良是生态恢复的核心问题与技术, 本文介绍了几种植被恢复中的土壤基质改良方法, 如施用营养物质、Ca^(2+)、施用石灰等改良剂, 并且就具体问题提出了表土转换、生物修复、植被恢复等土壤基质改良措施。最后提出了矿山废弃地土壤改良中所存在的问题。

A great of resources land was destroyed and occupied in the mining wasteland.So these Ecological Restoration has become the worlds especially Chinese anxious problem.Soil media is core problem and technique of the biology resumption in the mining wasteland.The paper introduces a few of improving ways of soil media in the Ecological Restoration.Such as throw nourishment material,Ca 2+ 、use the lime etc.And put forward surface soil conversion,biology rehabilitation,vegetation renewed etc.Finally put forward the problem of soil medias amelioration in the mining wasteland.
