Abstract

The invention provides a vegetation ecological restoration method for a southern high and steep hard slope. The invention discloses a vegetation ecological restoration method for a southern high and steep hard slope. The vegetation ecological restoration method comprises the following steps of S1, slope pretreatment and stability strengthening, S2, adaptive matrix construction and spray-seeding, S3, adaptive vegetation type selection and planting and S4, long-acting maintenance and monitoring. According to the vegetation ecological restoration method for the southern high and steep hard slope, the safety and stability of the slope are remarkably enhanced through systematic slope pretreatment and stability strengthening, a specially-optimized adaptive matrix formula, scientifically-selected vegetation combination and a refined long-acting maintenance monitoring system; according to the method, the survival rate and stability of vegetation communities are improved, stage-by-stage maintenance management and system monitoring evaluation are carried out, differentiated maintenance measures are provided according to the vegetation restoration rule, the slope stability and the vegetation growth condition are mastered in time, long-term stability and continuous improvement of the ecological restoration effect are ensured, and the sustainability of the ecological restoration effect is guaranteed.
