Abstract

Given the complexity of the environmental risks associated with tailings ponds (TPs) and the increasing impact of natural disasters in China, establishing a combined environmental and disaster risk assessment framework for TPs is crucial. Most existing studies have been limited to specific regions or individual TPs, leaving the national risk characteristics of TPs unclear. To address these gaps, this study developed an environmental risk assessment database, covering 7,232 TPs in China. A combined analytic hierarchy process and entropy weight method was used to construct the risk assessment framework, which integrates inherent hazard levels, control mechanisms, environmental sensitivity, and disaster impacts. The national-scale evaluation revealed that 21.93% of the TPs in China, primarily located in southern China and the Qinling Mountains, face high risks. High inherent hazard levels, such as mineral species and operational status, are major contributors to these elevated environmental risks. Rainstorms and landslides have a compounded effect on the TPs’ environmental risks, exacerbating them, particularly in Yunnan and Hunan. In contrast, the spatial distribution of TPs does not coincide with areas of high peak ground acceleration, thereby reducing the potential impact of seismic activity on TPs. In summary, this study provides a scientific basis for the risk management and natural disasters adaptation of TPs in China. Considering the compounded effect of rainstorm on the environmental risks of TPs, the importance of addressing the impacts of climate change, warranting attention.

中国尾矿库环境与自然灾害综合风险评价及多元响应分析

鉴于中国尾矿库环境风险的复杂性和自然灾害的影响日益严重，建立尾矿库环境与灾害风险综合评估框架至关重要。大多数现有的研究都局限于特定地区或个体TPs，使TPs的国家风险特征不清楚。为了解决这些问题，本研究建立了一个环境风险评估数据库，涵盖了中国7232个TPs。采用层次分析法和熵权法相结合的方法构建了综合固有危害等级、控制机制、环境敏感性和灾害影响的风险评价框架。全国评价结果显示，全国有21.93%的旅游项目面临高风险，主要分布在华南地区和秦岭地区。矿物种类和作业状况等固有的高危险程度是造成这些环境风险升高的主要因素。暴雨和山体滑坡对三峡项目的环境风险产生了复合影响，加剧了这些风险，尤其是在云南和湖南。相比之下，TPs的空间分布并不与地面加速度峰值区域重合，从而降低了地震活动对TPs的潜在影响。综上所述，本研究可为中国tp风险管理和自然灾害适应提供科学依据。考虑到暴雨对tp环境风险的复合影响，应对气候变化影响的重要性，值得重视。
