摘　　要：以广西兴安县碳酸钙精深加工新型材料产业园岩质边坡生态修复工程作为研究对象,对其灌溉系统设计、边坡修复、基材配制、植物选配、养护管理等多方面进行了探讨,通过对高陡采石场边坡降坡,在确保坡面稳定的前提下,合理规划灌溉方式,选择和设计科学适宜的目标植物群落和植生措施,解决后续植物生长、群落演替过程中的水土流失问题。针对高陡采石场边坡植生困难的问题,采用“削坡+挂网喷混植生袋+V型槽”组合植生方式,起到良好的固坡效果且有效地保证植物全覆盖,快速重建生态景观;乔灌草藤结合的多元植物模式及合理的基材配制设计、灌溉系统及长期管护,保证植物常青,可有效减少植被退化问题,并有利于在其他同类型项目推广,意义重大。The ecological restoration project of rock slope in Xing’an County of Guangxi calcium carbonate intensive processing new material industrial park discusses its irrigation system design, slope restoration, substrate preparation, plant selection and maintenance management. On the premise of reducing the slope of high and steep quarry to ensure the slope stability, the irrigation mode is reasonably planned. Scientific and appropriate target plant communities and vegetation measurement are selected and designed to solve the problem of water and soil loss in the process of subsequent plant growth and community succession. In view of the difficulty of planting on the slope of high and steep quarry, the combined planting mode of "slope cutting + hanging net spraying mixed planting bag + V-groove" is adopted to achieve a good slope consolidation effect, to ensure full plant coverage effectively and to reconstruct the ecological landscape quickly. The diversified plant model with the combination of arbor, shrub, grass and rattan, reasonable substrate preparation design, irrigation system and long-term management and protection ensure that the plants are evergreen, which can effectively reduce the problem of vegetation degradation. It is of great significance to promote in other similar projects.
