灵武矿区煤矸石山9种灌木配置的生长效果评价

以灵武矿区羊场湾煤矸石山为研究对象，采用样方法对其９种灌木的生长效果进行了调查，以群落植物生长效果为主要评价指标，分析了不同植被配置方式下煤矸石山覆土土壤上的植被生长效果，为煤矸石山植被修复提出科学建议。研究表明：9种灌木林中，紫穗槐林和多枝柽柳林综合生长效果最好，树高突出，成活率较高，生物量最大；蒙古莸林和黄刺玫林的综合生长效果最差。

Taking the Yangchangwan Coal Gangue Dump in the Lingwu Mining Area as the research object, this study employed the quadrat sampling method to investigate the growth performance of nine shrub species on the dump. Taking the growth performance of plant communities as the primary evaluation indicator, this study analyzed the vegetation growth performance on the soil-covered soil of the coal gangue dump under different vegetation configuration patterns, and proposed scientific recommendations for vegetation restoration of coal gangue dumps. The research results indicated that among the nine shrub stands, Amorpha fruticosa stands and Tamarix ramosissima stands exhibited the optimal comprehensive growth performance, featuring prominent tree height, relatively high survival rate and the maximum biomass; whereas the comprehensive growth performance of Caryopteris mongolica stands and Rosa xanthina stands was the worst.
