“…The concept of "patches" refers to the fragmentation of urban areas into smaller, more manageable units [293]. This fragmentation can take various forms, including dividing a city into smaller districts, creating green corridors, or implementing buffer zones between land uses [205]. Higher numbers of patches indicate greater landscape diversity and connectivity, which can enhance flood resilience by providing multiple pathways for water flow [133,139,261].…”

“…More patches can lead to a more fragmented urban landscape, slowing floodwater spread and reducing flooding risk in adjacent areas. It implies that smaller, more manageable units can be more easily managed and adapted to changing conditions, including climate change and increased flood risk [36,140,205]. However, the effectiveness of patches in enhancing FR depends on several factors, including the size and distribution of the patches, the types of land uses within each patch, and the presence of buffer zones or green corridors that can absorb and store floodwater [187,288,294].…”

Despite the increasing number of flood studies, the interrelationships between urban form indices (UFIs) and flood resilience (FR) have received little attention and hold miscellaneous perspectives. Consequentially, this study identifies how UFIs at various spatial scales affect FR by synthesizing article findings and proposing insights for future research. Scientometric analysis has been used to analyze the gathered peer-reviewed articles from nine research engines without time restrictions. One hundred and eighteen relevant articles were included and thoroughly investigated using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. Our findings indicate that divergent and dialectical perspectives about the efficacy of UFIs are due to multiple disciplines, methodologies, and different case study contexts. The included studies were classified according to urban scale as macro (citywide), meso (districts), micro (block), and multi-scalar analysis by 80.5%, 6.8%, 10.2%, and 2.4%, respectively. Furthermore, the included studies were categorized based on analysis type into realistic case studies, literature reviews, modeling, and hybrid analysis, with 74.6%, 7.6%, 14.4%, and 3.4%, respectively. At the macroscale, city density and spatial distribution degree have the most significant effect on FR. At the same time, mixed uses, connectivity, coverage ratio, block arrangements, and street characteristics are on the meso and micro scales. Further studies on the trade-offs and commonality between UFIs, FR, and overall urban resilience are required to shape climate-adaptive, sustainable communities.

Land use conflicts (LUCs) arise during land use change, causing an uncoordinated spatial structure of the land and negatively affecting the synergistic development of multifunctionality, especially in mountain cities. Previous studies have focused on identifying and measuring land use structural conflicts (LUSC), with less attention paid to land use functional conflicts (LUFC), and a lack of simulation for future multi‐scenarios. Thus, taking Chongqing as an example, based on the perspective of LUSC–LUFC coupling, this study constructed a comprehensive conflict index to identify and assess LUCs, then applied the PLUS model to predict LUCs under three development scenarios in 2030. This study found that (1) there was a significant positive spatial association between LUSC and LUFC, with high–high agglomeration types in areas of severe LUCs and low–low agglomeration types in areas of light LUCs. (2) During 2000–2020, the LUCs in Chongqing displayed a trend of upward and then downward from 2000 to 2020, with significant agglomeration in their spatial pattern. (3) Two typical areas of LUCs intensification were identified, namely the topographic transition zone located in the Daba and Wuling mountains and the urban–rural interface in the Chongqing metropolitan area. (4) In 2030, the LUCs in Chongqing manifest an overall mitigation in the ecological protection (EP) scenario, while displaying an intensification in the natural development (ND) and economic development (ED) scenarios. Based on the types of spatial interaction between LUSC and LUFC, land use optimization strategies were formulated. The findings will provide scientific references for sustainable land use management decisions in Chongqing and other mountainous cities.
