- 摘要:
- [目的]解决裸露边坡植被恢复初期覆盖无纺布所带来的环境污染和视觉污染等问题，探索无污染环保型的绿色养护技术，为农业废弃物（如作物秸秆等）的资源化利用寻找一条有效途径。[方法]利用人工修筑的土石边坡，分25°的阳坡和阴坡、35°的阳坡和阴坡，采用撒播+覆盖不同材料不同规格的无种子纤维植被毯、直接覆盖不同材料不同规格的带种子纤维植被毯，分析了不同纤维植被毯覆盖对物种种类、植被盖度、地上部分生物量、植被生活型以及生物多样性的影响。[结果]（1）300g/m2的椰丝纤维植被毯在先撒播后覆盖的方式下对裸露边坡植被恢复效果最好。（2）300g/m2椰丝纤维植被毯在先撒播后覆盖的方式下恢复植被的盖度及生物量较大。（3）有纤维植被毯覆盖的样地，植被生长情况较好，植被的生活型差异不显著（p>0.05），但是植物数量显著优于裸地（p<0.05）。（4）椰丝植被毯通过带种植被毯覆盖的样方多样性更好，丰富度、物种均匀度更高，优势度物种较少，更适合不同植物种的生长发育。[结论]植被毯覆盖对样地生物量、生物多样性、丰富度及物种均匀度均具有明显的促进作用，未来对裸露边坡可以广泛使用植被毯覆盖方式促进植被恢复及植被生长。
- 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.
