摘 要：
为探究不同恢复方式下煤矸石山植被恢复情况,选取大同市晋华宫人工修复煤矸石山和自然恢复煤矸石山以及忻州窑自然恢复煤矸石山为研究对象,对三座煤矸石山的植物群落状况进行调查分析,并探讨其土壤方面的驱动因素。结果表明,晋华宫人工修复煤矸石山分布有4科4属4种植物;晋华宫自然恢复煤矸石山分布有6科10属10种植物;忻州窑自然恢复煤矸石山分布有5科7属8种植物;由置换多元方差分析和非度量多维度分析结果可知,忻州窑自然恢复煤矸石山的植物群落与晋华宫人工修复、晋华宫自然恢复煤矸石山植物群落差异显著,而晋华宫人工修复和自然恢复煤矸石山间植物群落差异不显著,晋华宫人工修复和自然恢复煤矸石山优势植物均为中华草沙蚕,忻州窑自然恢复煤矸石山的优势植物为菊叶香藜,表明地理位置显著影响煤矸石山的植物群落构建;人工修复10～20年的植物群落可达到与自然恢复50～60年较一致的效果,即人工修复可以缩短煤矸石山植物群落恢复的时间;土壤全氮、有效磷和丛枝菌根真菌孢子密度是影响植物群落差异的重要因素。

摘 要：
To explore the vegetation restoration of coal gangue hill in different restoration patterns, we selected three different coal gangue hills(artificial restoration and natural restoration coal gangue hill of Jinhua Palace in Datong City;artificial restoration coal gangue hill of Xinzhou kiln), investigated the plant communities and soil driving factors.Results as followed: 4 species belonged to 4 genera of 4 families were discovered in artificial restoration coal gangue hill of Jinhua Palace, and 10 species belonged to 10 genera of 6 families were found in natural restoration coal gangue hill of Jinhua Palace; while there were 8 species belonged to 7 genera of 5 families in natural restoration coal gangue hill of Xinzhou Kiln. Based on the permutational multivariate analysis and nonmetric multidimensional scaling analysis,significant differences in plant communities were found between the natural restoration coal gangue hill of Xinzhou Kiln and the artificial restoration and natural restoration coal gangue hill of Jinhua Palace, however, no significant differences were found between artificial restoration and natural restoration coal gangue hill of Jinhua Palace. The dominant species was Tripogon chinensis in Jinhua Palace and was Chenopodium foetidum in Xinzhou Kiln, which indicated that site conditions strongly influenced plant community construction. The artificial restoration of plant communities for 10-20 years could achieve the same effect as the natural restoration for 50-60 years, that is,artificial restoration can shorten the recovery time of plant communities in coal gangue. Plant community was significantly influenced by soil total nitrogen and available phosphorus and AMF spores density.
