摘　　要：为评估神东矿区的植被恢复治理成效,从群落物种丰富度、物种个体总数、群落总盖度及物种多样性等方面分析了矿区典型植物群落随治理年限延长而呈现出的发展趋势。从分析来看,沙棘群落和柠条(柠条锦鸡儿)群落随治理年限延长表现出总体向好的发展趋势,后期基本不需人为干预,表现出良好的水土保持效益;而沙柳(乌柳)群落随治理年限延长表现出总体向差的发展趋势,后期需要人为干预和管理才能发挥较好的水土保持效益。In order to evaluate the effect of vegetation rehabilitation control of Shendong mining area,the paper analyzed the development trend showed along with the extension of treatment years of typical plant community of the mining area from the aspects of community species richness,total number of individual species,total community coverage and species diversity. From the perspective of analysis,Hippophae rhamnoides community and Caragana korshinskii community show overall better development trend along with the extension of treatment years. In the later stage,there is basically no need for human intervention,showing good effectiveness in soil and water conservation control. While Salix cheilophila community shows overall worse development trend along with the extension of treatment years and it needs human intervention and management in the later stage for playing better treatment effect.
