基于DPSIR的城市雨水管网韧性评估

Assessment on Toughness of Urban Rainwater Pipeline Network Based on DPSIR

摘要:

随着全球气候变化，城市面临着越来越多的极端降雨事件和洪水灾害。作为城市基础设施的关键组成部分，城市雨水管网对于雨水的分流和处理具有重要意义。以城市雨水管网为基础，结合韧性理论，利用DPSIR模型构建了城市雨水管网韧性评价指标，并建立“组合赋权-可拓云”评估模型，最后利用实例进行验证，对韧性指标进行量化、将评价结果可视化呈现，以更好地帮助决策者和城市规划者理解和应对城市雨水管网的挑战和风险。

Abstract:

With the global climate change, cities are confronted with an escalating number of extreme rainfall and flood disasters. As a significant component of urban infrastructure, the urban rainwater pipeline networks is of great significance for rainwater diversion and treatment. Based on the urban rainwater pipeline networks and in combination with the toughness theory, the DPSIR model is used to build a toughness evaluation index of urban rainwater pipeline network. And an "integrated weighting - extension cloud" evaluation model is established. Finally, the verification is carried out through practical examples, the toughness indicators are quantified and the evaluation results are presented visually in order to better assist the decision-makers and urban planners in understanding and addressing the challenges and risks of urban rainwater pipeline networks.
