In order to comprehensively understand the service function of Rhus typhina (an exotic species), the biomass and carbon storage of eleven-year-old R. typhina community in bare land and desolate sloping field in the hilly area of Taihang Mountain were investigated. The results were as follows: The exponential equations of biomass of different components about the basal diameter and tree height were established, and the regression coefficient reached more than 0.92, which achieved significantly positive levels. It was calculated that the biomass of R. typhina community in bare land and desolate sloping field were 13.395 4 t·hm-2 and 29.106 4 t·hm-2 respectively, and higher than that of native shrub in this area. The average carbon content of R. typhina was 44.56% and the vegetation carbon stock in these two kinds of R. typhina community were 5.915 5 t·hm-2 and 12.975 1 t·hm-2 respectively. In addition, the top soil (0 ~ 20 cm) carbon stock in barren sloping field was 2.172 2 kg·m-2 and the total carbon stock of eleven-year-old R. typhina community achieved at 34.697 1 t·hm-2, so it was obvious that R. typhina was superior to native shrub in the aspects of material production and carbon sequestration ability.%为全面了解外来种火炬树的生态服务功能,研究了太行山南端低山丘陵区岩石裸露地和自然荒坡二种生境营造的11年生火炬树人工林的生物量与碳贮量.主要结果为:建立了火炬树各器官生物量和基径、树高的回归方程,回归系数均在0.92以上,都达到极显著水平,可以用于研究地区火炬树生物量的测算；石裸地和荒坡地火炬树群落生物量分别达到13.395 4 t·hm-2和29.106 4 t·hm-2,高于同地区乡土灌丛的生物量；火炬树平均含碳率44.56％,石裸地和荒坡地火炬树群落植物层碳贮量分别达5.915 5 t·hm-2和12.975 1 t·hm-2,荒坡0～20 cm土壤碳密度为2.172 2 kg·m-2,荒坡11年生火炬树群落总碳贮量达34.697 1 t·hm-2.从物质生产和碳存贮能力来看,外来种火炬树优于当地同生境的乡土灌木树种.
