摘　　要：采用野外调查和统计分析相结合的方法,对孙家湾矸石山阳坡不同排矸年限地段物种多样性进行研究。结果表明:在不同排矸年限地段,物种组成变化较大,由排矸初期的4科4种发展为后期的6科19种,并由草本群落逐渐演变为榆树疏林。物种综合多样性指数、物种丰富度指数与排矸年限呈显著的正相关关系,Alatalo均匀度指数与排矸年限呈显著的负相关关系。The species diversity of different gangue piles at sunny slope in Sunjiawan was studied with field investigation and statistical analysis. The results show that obvious changes in species components of different gangue piles took place, from 4 species of 4 families at the initial stage of dumping gangue to 19 species of 6 families at the back stage , and from herb community to sparse elm tree community. There was prominent positive correlation between diversity index, species richness index and dumping years. However, there was prominent negative correlation between Alatalo evenness index and dumping years.
