岷江上游（闽江上游）位于中国西南地区，山地聚居较多，地质灾害频发。通过实地调查、整理年鉴数据并利用SPSS统计软件分析，建立了地质灾害脆弱性评价指标体系。根据现场实际情况和研究区2006年、2009年、2015年获取的数据，选取16个指标作为地质灾害沉降脆弱性评价指标。这些指标包括人口密度、建筑覆盖率和经济密度。基于熵值综合评价模型，分析地质灾害沉降脆弱性的动态变化。结果表明，人口密度、建筑覆盖度、经济密度、道路密度是影响地质灾害沉降脆弱性的最大因素——汶川地震对岷江上游地区造成了较大破坏，2009年该地区是最脆弱的地区。但2015年脆弱性有所下降，表明震后重建取得了明显成效。因此，脆弱性已成为反映山地聚落安全健康发展的重要指标。
The upper reaches of Min River (The upper Min River) is located in Southwest China with significant mountain settlements, which are vulnerable to frequent geological hazards. Based on a field investigation, collation of yearbook data, and analysis through the use of SPSS statistical software, a vulnerability evaluation index system of geological hazards was devised. According to the actual field situation and the acquired data of the study area in 2006, 2009, and 2015, 16 indicators were selected as settlement vulnerability evaluation indexes of geological hazards. The indexes included population density, building coverage, and economic density. Based on the comprehensive evaluation model of entropy value, the dynamic change in the settlement vulnerability of geological hazards was analyzed. The results showed that population density, building coverage, economic density, and road density were the factors that affected the settlement vulnerability of geological hazards the most—Wenchuan earthquake caused considerable damage to the upper Min River, making the area the most vulnerable in 2009. However, its vulnerability decreased in 2015, which indicated that postearthquake reconstruction achieved significant results. Thus, the vulnerability has emerged as an important indicator reflecting the safety and healthy development of mountain settlements.
