摘　　要：地震滑坡地质灾害会产生严重的负面影响,为了将灾害影响降至最低,提出地震滑坡地质灾害危险性评价方法,研究生态修复策略。选择地震活动频繁的区域作为研究区域,从人为、自然两个方面确定地震滑坡地质灾害危险性影响因素。收集地震滑坡地质灾害数据,构建地震滑坡地质灾害危险性评价指标体系,根据数据收集结果计算评价指标的具体取值,考虑指标权重,得出评价结果。研究表明,优化设计方法得出的评价结果更接近实际灾害情况,根据评价结果,制定加设生态袋防护、充分应用液压喷播和客土喷播技术、植被与土壤恢复等生态修复策略。Earthquake landslide geological disasters will have serious negative effects.In order to minimize the impact of disasters,the risk assessment method of earthquake landslide geological disasters is put forward and the ecological restoration strategy is studied.The area with frequent seismic activity is selected as the research area,and the influencing factors of geological disaster risk of earthquake landslide are determined from man-made and natural aspects.The study collects the data of earthquake landslide geological disasters to construct the evaluation index system of earthquake landslide geological disasters.The specific values of evaluation indexes is calculated according to the data collection results,and consider the index weights to get the evaluation results.The research shows that the evaluation results obtained by the optimized design method are closer to the actual disaster situation.According to the evaluation results,ecological restoration strategies such as adding ecological bag protection,hydraulic spray seeding and exotic soil spray seeding technology,and restoring vegetation and soil are formulated.
