摘要
滑坡危险性评价能够为防灾减灾和区域规划提供有效的理论依据,为使滑坡危险性区域评价结果更为客观、准确,首次引入物元分析理论,结合组合赋权,构建基于物元分析法与组合赋权的滑坡危险性评价模型。首先结合前人研究选取高程、坡度、坡向、土地类型、道路距离、水文条件、降雨量、断裂距离和地层岩性等9个滑坡影响因子,利用改进层次分析法(analytic hierarchy process,AHP)确定各指标的主观权重,确保了判断矩阵的一致性检验更易满足。其次根据熵权法计算各指标的客观权重。基于博弈论原理组合赋权,将组合权重作为物元分析法的输入权重,建立滑坡危险性评价模型。最后,为了验证上述所提模型的有效性,以陕西省商洛市山阳县为研究区,对其进行滑坡危险性评价,所得评价结果准确率为96%,相较于AHP-FCE模型和改进AHP-物元分析模型分别提高了0.22、0.07,为其他同类型的研究区域的滑坡危险性评价提供了借鉴。
Landslide risk assessment can provide an effective theoretical basis for disaster prevention and mitigation and regional planning, in order to make the evaluation results of landslide risk areas more objective and accurate, the theory of matter-element analysis is introduced for the first time, combined with combination of combination empowerment, and a landslide risk evaluation model based on material-element analysis method and combinatorial empowerment is constructed. Firstly, based on previous studies, 9 factors such as elevation, slope, aspect, land type, road distance, hydrological condition, rainfall, fault distance and stratum lithology are selected, the subjective weight of each index is determined by improved analytic hierarchy process(AHP), which ensures that the consistency test of judgment matrix is easier to satisfy, and the objective weight of each index is calculated by entropy weight method. Based on the combination weight of game theory, the combination weight is taken as the input weight of matter-element analysis, and the landslide risk assessment model is established. Finally, in order to verify the validity of the proposed model, in the research area in Shanyang County, Shangluo City, Shaanxi Province, the evaluation rate was 96%, which improved 0.22 compared with the AHP-FCE model and the AHP and 0.07 respectively, providing a reference for the landslide risk assessment of other research areas of the same type.
