纤维植被毯覆盖对裸露边坡植被恢复效果的影响
Effect of fiber vegetation blanket coverage on vegetation restoration of bare slopes
摘要
Abstract
[Objective]To address environmental and visual pollution caused by non-woven fabric coverage during the initial stage of vegetation restoration of bare slope,this study explores pollution-free and environmentally friendly green maintenance technology,and looks for an effective way for the resource utilization of agricultural waste(such as crop straw,etc.).[Methods]Using the artificially constructed earth-rock slopes,divided into 25° sunny and shady slopes,35° sunny and shady slopes,this study employed two approaches:broadcasting seeds followed by covering with non-seeded fiber vegetation blankets of different materials and specifications,and directly covering seeded fiber vegetation blankets of different materials and specifications.The effects of different fiber vegetation blanket coverage on species diversity,vegetation coverage,above-ground biomass,vegetation life forms and biodiversity were investigated.[Results](1)The 300 g/m2 coconut fiber vegetation blanket had the best effect on vegetation restoration of bare slope under the method of first seeding and then covering.(2)The vegetation coverage and biomass of 300 g/m2 coconut fiber vegetation blanket were larger under the method of first seeding and then covering.(3)In the plots covered with fiber vegetation blankets,vegetation growth was better,and the difference in vegetation life form was not significant(p>0.05),but the number of plants was significantly better than that on bare slope(p<0.05).(4)The coconut vegetation blanket had better diversity,higher richness,higher species uniformity,and fewer dominant species when used in plots covered with planting blankets,which is more suitable for the growth and development of different plant species.[Conclusion]Vegetation blanket coverage can significantly promote the biomass,biodiversity,species richness and species evenness of sample plots.In the future,vegetation blanket coverage can be widely used to promote vegetation restoration and growth of bare slopes.关键词
