摘要
按照不同立地的植被类型,对太原西山4个煤矿废弃地的植被恢复效果进行分析,采用主成分综合模型对植被修复后土壤的理化性质进行定量评价。结果显示,侧柏林对土壤理化性质的改良效果最佳,其次是农林复合林、护坡林、杨树林、风景园林;紫穗槐林对土壤的改良效果最差。侧柏林为煤矿废弃地的最优植被恢复类型。
According to vegetation types of different site,the vegetation restoration effect of 4 coal mine wastelands in Taiyuan of Xishan was analyzed.The physical and chemical properties of soil after vegetation restoration were evaluated quantitatively by using principal component comprehensive model.Results showed that Platycladus orientalis forest had the best improvement effect on physical and chemical properties of soil,which followed by agroforestry,slope-shelter forest,Populus forest and landscape architecture.The improvement effect of Amorpha fruticosa forest on soil was the worst.So the best vegetation restoration type of coal mine wasteland was Platycladus orientalis forest.
