An impervious surface is considered one of main factors affecting urban waterlogging. Previous studies found that spatial pattern (composition and configuration) of impervious surfaces affected urban waterlogging. However, their relative importance remains unknown, and the scale-effect of the spatial pattern on urban waterlogging has been ignored. To move forward, our research studied the relationship between spatial patterns on the impervious surface and its subcategories (building and pavement) on urban waterlogging risk spots using Pearson correlation, partial redundancy analysis and performed at three grid scales (1 km × 1 km, 3 km × 3 km, 5 km × 5 km) and the catchment scale based on different spatial resolution land cover maps (2 m, 10 m and 30 m). We identified positively-correlated metrics with urban waterlogging risk spots, such as the composition of impervious surface (i.e., total impervious surface, building, pavement) and the aggregation metric of the total impervious surface at most scales, as well as two negatively correlated metrics (i.e., proximity metric of building, fragmentation metric of total impervious surface). Furthermore, the total variance of urban waterlogging risk spots explained by the spatial pattern of the total impervious surface and its subcategories increased with studied grid and catchment scales while decreasing from a fine to a coarse resolution. The relative contribution of the impervious surface composition and configuration to the variation of urban waterlogging risk spots varied across scales and among impervious surface types. The composition contributed more than the configuration did for the total impervious surface at both grid and catchment scales. Similar to total impervious surface, the composition of buildings was more important than its configuration was at all the grid scales, while the configuration of buildings was more important at the catchment scale. Contrary to the total impervious surface, the configuration of pavement at both the grid and catchment scales mattered more than their compositions did. Furthermore, the composition of the building was more important than that of pavement, but its configuration mattered less. Our study could provide a multi-scale landscape perspective with detailed suggestions for controlling the area of impervious surface and optimizing its spatial configuration in urban waterlogging risk mitigation and urban planning.

Public-private partnerships (PPPs) have been increasingly adopted in China. Sustainability of PPPs has become a priority for a sustainable development of PPPs. Most prior studies focus on sustainable implementation of PPP projects. Few research efforts have been done to examine the impacts of PPPs to sustainability from an external perspective and a more macro geographical scale. Meanwhile, the social aspect of the sustainability of PPPs has not been widely studied. Therefore, this study aims to propose a social sustainability contribution evaluation system (SSCES) for PPPs to evaluate PPPs' contribution to regional social sustainability at the institutional level. An indicator system of the SSCES for PPPs was developed, which included 8 requirements for socially sustainable development and 33 social sustainability indicators. The weights of indicators were determined by using the analytic hierarchy process method. The results indicate that, in the context of China, promoting peopleoriented urbanization in PPPs can help enhance regional social sustainability. This study provides a useful evaluation tool for various stakeholders to evaluate the sustainability of PPPs from an institutional level, especially for local governments to review current PPP polices and make improvements.

“…According to [12], education and income have a positive effect on WTP to support sponge city initiatives in two cities (Zibo and Dongying, Shandong Province) of China. A recent comparative study (UK, USA, China and Germany) on the impacts of flooding on property values has revealed that there is generally a lack of information on the impact of flood risk on land and housing markets at present.…”

Rapid urbanization in China and global climate change have increased urban flood exposure in Wuhan, and the increased flood risk has reduced property values in flood-prone areas. The central government of China is promoting the application of the sponge city concept to reduce urban flood risk and improve the environment in cities. Wuhan is one of the pilot cities of this initiative. A shortage of funds is one of the main obstacles to sponge city construction, as is the lack of a suitable business model. To test residents' willingness to pay for sponge city construction, this research analyzed the impact of sponge city construction on the housing values of areas covered by sponge city interventions. The authors conducted interviews and analyzed secondary data to gauge residents' awareness and perceptions of sponge city interventions. The results show that more than half of residents in Wuhan are willing to pay for sponge city measures, but the amount they are willing to pay is limited. Residents are more willing to pay for improvements of their living environment than for flood reduction measures.
