DEMATEL-ISM method and MICMAC model were used to analyze the dependence and driving force of five influencing factors. Based on PLS-SEM model, the hierarchical structure and action path of the influencing factors were quantitatively analyzed through 39-sample cities in China. Simultaneously, the relationship between spatial form and Urban Green Transformation Efficiency (UGTE) and its reasons are qualitatively analyzed. The main conclusions are as follows: (1) The urban spatial system affects urban productivity. (2) Economy, environment, and infrastructure are highly interdependent, with minimal driving force. In contrast, society and space have a larger driving force and are less dependent. (3) In resource-exhausted cities, economy has the greatest impact on UGTE (0.367***), followed by infrastructure (0.358***) and environment (-0.160***). The path coefficients of spatial impact on economy, environment, and infrastructure were 0.337, 0.741, and 0.564, respectively. The path coefficient of social influence on economy is 0.564***.

The theoretical contributions of this study are as follows: (1) for the first time, an analysis framework that includes spatial factors influencing UGTE is proposed; (2) the study explores sustainable urban form and establishes a research paradigm for related studies. The practical contributions include providing guidance for the medium- and long-term spatial planning of different resource-based cities. For example, resource-exhausted cities in the decline stage should adopt a compact spatial form of functions.

Blue-green infrastructures (BGI) are recognised for their heat mitigating effects. However, urban settlements frequently face spatial constraints, that hinder their implementation. Consequently, this article introduces a methodological approach to systematically describe and assess urban street space to indicate possible space availability for BGI implementation in dense urban areas. We propose two scenarios, one context sensitive and one more disruptive, to free up and increase available space by altering current street usage while maintaining initial street functionality. Compositions of BGI were implemented in the scenarios according to space availability and their anticipated heat mitigation potency. Microclimatic computer simulation served to assess related temperature reducing capacities of the newly implemented BGI. The methodological approach was applied in a historic part of Vienna, Austria. Investigations clearly showed a positive correlation of the extent of BGI implementation and the reduction of physiological equivalent temperature (PET). Correlating space consumption and temperature reducing capacity of BGI implementations revealed differences in microclimatic and spatial efficiency. Most efficient reductions of PET were observed when 10–25 % of street surface was allocated for BGI. Our study suggests that allocating around 10 % of street surface for new BGI implementation can lead to considerable reductions of PET emphasising the potential for effective urban heat mitigation strategies. The results and the method developed provide new insights and possibilities for strategic urban planning, implementing heat mitigation strategies in dense urban areas while supporting existing concepts for the sustainable transformation of cities.</div></div>","PeriodicalId":48659,"journal":{"name":"Sustainable Cities and Society","volume":"126 ","pages":"Article 106391"},"PeriodicalIF":10.5,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143918057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
