Abstract

ABSTRACT As a result of rapid urbanization and climate change, many large- and medium-sized cities in China frequently undergo urban disasters with severe impacts that result in many casualties, induce significant economic losses, and restrict sustainable social and economic development. Providing timely and accurate early warnings is the most effective measure for disaster prevention and mitigation before such disasters can impose severe impacts. In this study, we propose a dynamic impact assessment method for rainstorm waterlogging using land-use data. First, based on a detailed collection of disaster prevention and mitigation data, we construct an impact assessment index based on the assessment objects of this study. Then, a waterlogging simulation is performed, and the simulation results are found to meet the assessment requirements. Finally, we conduct an impact assessment every half hour during a heavy rainfall event and evaluate the performance of the proposed method by assessing the socioeconomic impact, object impact, industry impact, regional impact, and comprehensive impact of the event. These assessments produce valuable information for providing diverse and timely services in the event of urban waterlogging.
基于土地利用数据的暴雨内涝动态影响评价方法
由于快速城市化和气候变化,中国许多大中城市频繁发生城市灾害,灾害影响严重,人员伤亡惨重,经济损失巨大,制约了社会经济的可持续发展。提供及时和准确的预警是在灾害造成严重影响之前预防和减轻灾害的最有效措施。本文提出了一种基于土地利用数据的暴雨内涝动态影响评价方法。首先,在详细收集防灾减灾数据的基础上,构建了基于本研究评估对象的影响评价指标。然后进行了内涝模拟,模拟结果满足评价要求。最后,我们在强降雨事件中每半小时进行一次影响评估,并通过评估事件的社会经济影响、对象影响、行业影响、区域影响和综合影响来评估所提出方法的性能。这些评估为在城市内涝事件中提供多样化和及时的服务提供了宝贵的信息。

期刊介绍: Journal of Integrative Environmental Sciences (JIES) provides a stimulating, informative and critical forum for intellectual debate on significant environmental issues. It brings together perspectives from a wide range of disciplines and methodologies in both the social and natural sciences in an effort to develop integrative knowledge about the processes responsible for environmental change. The Journal is especially concerned with the relationships between science, society and policy and one of its key aims is to advance understanding of the theory and practice of sustainable development.
