“…To alleviate the conflict between economic development and the ecological environment, exploring the coordinated symbiosis of production, ecology, and living space is an important path to promote sustainable development 53 . Strengthening the construction of green infrastructure can also present a certain buffer role for cities to withstand natural disasters 54 . The expansion trend of urban construction land in highly urbanized areas has intensified, and the phenomenon of idleness has been highlighted.…”

Optimizing the spatial layout of the national territory is crucial for realizing the transformation and development of resource-oriented cities in the context of high-quality development in the new period. This paper takes Tongling City as a case study, based on the analysis of the historical development foundation, then uses the SD-FLUS comprehensive model to carry out a systematic analysis of the transformation in five dimensions of economy, society, population, science and technology, resources and environment, and discusses the optimization of spatial pattern under the contextual simulation. The conclusions are as follows: ① The hierarchical framework of “system-indicator-element” is not only internally interconnected, but also inextricably linked with the relationship between the various categories of the land use system. ② Decrease of cropland, forest, water, grassland, and barren decreases from the economic development, social progress, and comprehensive development, and there is a small increase in the area under the scenario of resource and environmental protection, and the direction of the change of the impervious is in the opposite direction. ③ Cultivated land is retained in situ and concentrated to a small extent, forested land is reduced to a small extent while the status quo is maintained, and the Yangtze River water system will be retained and protected to a large extent, but part of the waters of Zongyang County will give way to the expansion of construction land under the development objectives of the new county. Building land will be expanded and extended to the northeast in the original site area, while the southwest corner of the original county center will be expanded to some extent in Zongyang County to promote the county’s economic development.

“…Based on a recent cost–benefit analysis study on SCP facilities 45 , bioswales have a total unit cost of 1580.39 RMB/m 2 . We estimated that an increase of 2% in bioswales would take about 1.6 × 10 8 RMB, and an increase of 4% in bioswales would cost about 3.2 × 10 8 RMB in Cicheng New Town.…”

“…We estimated that an increase of 2% in bioswales would take about 1.6 × 10 8 RMB, and an increase of 4% in bioswales would cost about 3.2 × 10 8 RMB in Cicheng New Town. The necessary expenditure is high, but the advantages to society, the economy, and the environment are also substantial 45 , 46 . Past studies in Ningbo have explored community perceptions of and engagement with NbS, finding that future improvements in perception and engagement were likely to be substantial and that raising public awareness of SCP practices could encourage stronger co-production 47 .…”

Nature-based solutions (NbS), including China's Sponge City Program (SCP), can address the challenges urban communities face due to surface runoff and flooding. The current capacity of SCP facilities in urban environments falls short of meeting the demands placed on communities by climate change. Bioswales are a form of SCP facility that plays an important role in reducing surface runoff by promoting infiltration. This study assesses the potential of SCP facilities to reduce runoff in urban communities under climate change using the storm water management model. The study site in Ningbo, China, was used to evaluate the potential role of bioswales in reducing runoff risks from climate change. We found that bioswales were most effective in scenarios when rainfall peaks occurred early and were less effective in right-skewed rainfall events. The overall performance of SCP facilities was similar across all climate scenarios. To maintain the current protection level of SCP facilities, bioswales would need to cover at least 4% of the catchment area. These findings from Ningbo provide a useful method for assessing NbS in other regions and indicative values for the increase in the bioswale coverage needed to adapt to climate change.

“…Many documents also assessed pervious pavements within the GI [27,[56][57][58][59], from which pervious pavements usually present an intermediary cost per square meter among the alternatives. Usually, pervious pavements are good performers in runoff reduction and are more expensive than natural alternatives, such as bioretention and swales.…”

Life Cycle Assessment (LCA) and Life Cycle Cost Assessment (LCCA) are essential tools for environmental and economic assessment and decision-making in an evolving world with continuous climate change. In the same conditions, one of the most used and assessed solutions for facing climate change is using pervious pavements, with many papers proving its benefits. However, the literature has shown a need for more research on the LCA methodological aspects in the context of new green infrastructure. This research aims to review pervious pavements, LCA and LCCA combined, while discussing possible differences in boundaries, functional units, and other parameters. Thus, a string search was performed, leading to 89 documents. The main results indicate LCA is usually scope-bounded in the field of pervious pavements, with different benefits and characteristics, such as traffic impact, urban heat island effects, and carbonation. As for LCCA, private and public cost differentiation provide a scope definition and monetisation difficulties. In conclusion, both tools offer promising applications in pervious pavements. As a significant deliverable and recommendation of this paper, both LCA and LCCA theoretical frameworks were provided based on the benefits and specific characteristics included in the literature. These frameworks introduce novel ideas and perspectives, inviting further exploration and discussion.
