Abstract

To address stormwater management, China initiated the construction of sponge cities in 2014. Sponge city (SPC) construction in China has previously been evaluated using subjective expert methods. Based on China's SPC evaluation regulations, the evaluation criteria system was divided into 6 categories and 22 indicators. This study presents a multi-criteria approach to evaluating SPC construction through multi-criteria attributes value theory (MAVT). Coupled with the entropy method, this approach can reduce errors caused by individual methods. This work improved the evaluation method from a subjective to an objective method. Additionally, the sensitivity of an alternative to these criteria was conducted. The analysis reveals the inner relationship between the SPC alternative and the criteria. An actual SPC project, the city of Hebi, was selected as a case study. The findings indicate that the proposed approach is an efficient and simple approach. It can help decision makers better understand SPC performance, and it is a pilot SPC evaluation method using relatively objective means. This article is protected by copyright. All rights reserved.
