摘　　要：煤矸石风化物全量养分含量随着排矸年限的增加呈不同程度的上升趋势。除样地B的全钾量以外,表层土壤全量养分含量高于亚表层,阴坡高于阳坡。阴坡表层土壤与阳坡的土壤全氮量的增长趋势均呈两个阶段:排矸25 a以下,增长缓慢;而排矸25 a^40 a时,积累迅速,阴A样地表层全氮量增幅可达81.6%。阴坡亚表层土壤全氮量增长趋势与表层相反,在排矸8 a以下,增长迅速,而后期增长幅度平缓。全磷量增幅较小,且均低于对照农田,样地B与样地C之间无显著差异。土壤全钾量显著高于土壤全氮含量和全磷含量。多重比较表明,除阴D样地与阳B样地亚表层外,其余样地土壤全钾量均与对照农田地存在显著差异。The weathering material total nutrient content of gangue pile increased with the increase of dumping years.In addition to the kalium content of plot B,the total nutrient content of surface layer was bigger than sub-surface layer,and shady slope was better than sunny slope.The nitrogen content growth trend of surface layer at shady slope and sunny slope had two stages,increased slowly first,then accumulated quickly.The nitrogen content of plot A of 25～40 dumping years at shady slope surface layer increased 81.6%.The sub-surface layer at shady slope increased contrarily.The phosphorus content increased smaller,and less than farmland.Plot B and plot C no had difference.The kalium content was higher than the nitrogen content and the phosphorus content.Compared with farm,the kalium content differed greatly,beside plot D at shady slope and plot B sub-surface layer at sunny slope.
