| 本文以广州市南沙区露天采石场为例，选取了4种具有代表性的岩质边坡植被重建技术:板槽法、燕窝法、台阶法和挂网喷播法，通过2013—2023年的植被变化情况分析这些技术的治理效果。研究基于8个相近地形的露天采石场边坡，通过现场调查记录植被生长情况，分析立面治理效果。并结合高分一号卫星影像图，通过计算NDVI，分析边坡在时间、空间上的平面植被覆盖度特征，从多维度探讨不同修复技术的实际成效。结果表明:1)短期治理效果明显的以燕窝法整治为主，长期治理效果明显的以挂网喷播法、台阶法整治为主。2)台阶法整治效果在空间分布上最为稳定且覆盖度较高，时间变化特征上不同矿山变化趋势接近，受矿山环境影响较小。3)在治理后的第8年到第18年间，4种修复技术治理的边坡范围植被变化均呈现波动上升。 |

| In this paper，it took Nansha openpit quarry in Guangzhou as an example and selected four representative rock slope vegetation reconstruction technologies: plate groove method，bird’s nest method，step method and hanging net spray seeding method，and analyzed the control effect of these technologies through the vegetation change from 2013 to 2023The study is based on the slope of openpit quarries in 8 similar terrainsThe vegetation growth is recorded through field investigation，and the facade treatment effect is analyzedMoreover，combined with the GF1 satellite image，the NDVI is calculated to analyze the temporal and spatial characteristics of the planar vegetation coverage on the slope and explore the actual effectiveness of different restoration technologies from multiple dimensionsThe results show that: 1) The swallow’snest method is the main method for shortterm ecological restoration and treatment，while the netspraying method and the stepped method are the main methods for longterm ecological restoration and treatment2) The stepped method has the most stable and high coverage effect in spatial distribution，the temporal variation characteristics of different mines show similar trends and are less affected by the mining environment3) From the 8th to the 18th year after treatment，the vegetation changes within the slope range treated by the four repair techniques showed a fluctuating increase |
