摘　　要：探讨高寒区铁路工程迹地恢复中不同建植方式对植被恢复的影响,以期为快速、高效植被重建提供理论支持。研究结果表明:撒播处理的盖度均显著高于同处理条播(P<0.05),分别增加120.00%,55.76%,126.96%,地上生物量也均高于条播处理,分别增加36.47%,50.64%,53.98%(P<0.05),但条播处理的密度较撒播分别增加32.17%(P<0.05)、86.60%(P<0.05)、27.19(P>0.05);F2(无纺布覆盖)、F3(草帘覆盖)均能增加植被盖度,F2能不同程度增加植被密度。相较于条播,撒播更加有利于植被快速建植,两种覆盖方式均有利于植被盖度的增加,F3更有利于控制植被密度,适宜的种植密度会促进植株生长发育,增强植被恢复效果。This study aimed to examine the impact of diverse planting methods on vegetation restoration in abandoned land of railway engineering in high cold regions.The objective was to furnish theoretical underpinnings for expediting and optimizing the process of vegetation reconstruction.The findings revealed that broadcast treatment exhibited a substantially higher coverage than its counterpart(P<0.05),with an increase of 120.00%,55.76%,and 126.96%,respectively.Similarly,the aboveground biomass was also superior in the broadcast treatment,registering an enhancement of 36.47%,50.64%,and 53.98%(P<0.05),compared to the same treatment.When contrasted with broadcast sowing,drill sowing demonstrated a density increase of 32.17%(P<0.05),86.60%(P<0.05),and 27.19%(P>0.05).Both F2(nonwoven fabric cover)and F3(straw curtain cover)facilitated an increase in vegetation coverage,with F2 exerting a varying degree of influence on vegetation density.In summary,broadcast seeding was found to be more conducive to the swift establishment of vegetation compared to drill sowing.Both coverage methods contributed to the augmentation of vegetation coverage,with F3 being more effective in controlling vegetation density.An appropriate planting density was observed to foster plant growth and development,thereby enhancing the efficacy of vegetation restoration.
