Abstract ：
Existing literature has made substantial efforts to examine the relationships between land surface temperature (LST) and urban landscape patterns (ULPs). However, the inconsistent findings from studies on LST conducted in different cities lead to concerns about the significance and importance of ULPs. Moreover, insufficient attention has been paid to vertical ULPs and variations in their thermal effects over space and time. This study conducts a comparative analysis in 38 Chinese megacities across different seasons at the street block level to identify regularities and differences in ULP-LST linkages using geographical open data. The study quantifies ULPs with an amount of widely used and new two- and three-dimensional spatial metrics from three aspects-city plan patterns (CPPs), building patterns (BPs), and land use patterns (LUPs)-based on Conzen's townscape analysis framework. Results reveal that the consideration of overall or specific aspects of ULPs can enhance the explanation of spatial variations in LST, particularly during summer and spring. The improvements are highest for LUPs, followed by CPPs and BPs. Regardless of seasons and cities, building arrangement, built-up areas, greens, water bodies, elevation, slope, and road density are the most influential ULP indicators, whereas block size, sky view factor, building density, and building height present limited or unintended effects. Furthermore, our results indicate the time- and place-varying relationships between ULPs and LST, and some ULP indicators demonstrate two-sided effects on LST across different seasons or cities. We suggest that optimizing building layout and land use composition to increase green-blue spaces and urban shading zones may be more effective for alleviating the urban heat island effect than changing urban density.

Abstract ：
NO2 pollution in England has steadily improved in recent decades; however, disparities in exposure among ethnic groups have persisted and, in some cases, worsened. While much of the literature provides observational evidence of environmental injustice in England, few studies have examined the temporal evolution of these disparities or the role of policy in shaping them. This study leverages the COVID-19 lockdowns as a natural experiment to examine changes in ethnic disparities in NO2 exposure and quantify the differential impacts of lockdown policies. Using satellite-based NO2 measurements aggregated at the local authority district level, we discovered shrinking ethnic gaps in NO2 exposure from 2019 to 2021. Notably, while White populations consistently experienced lower NO2 exposure (at least 5 mu g/m3 lower) compared to Asian and Black groups, larger reductions in NO2 were observed in districts with higher proportions of non-White residents (e.g., 7.29 mu g/ m3 reduction for Asian population in 2020). Regression results show the effect of lockdown policies on ethnic disparities in NO2 reduction remained significant after controlling for mobility, income, urbanity and road density. This study highlights the equity implications of air quality policies and underscores the need for targeted interventions to alleviate the disproportionate NO2 exposure burden on ethnic minorities in England.

Abstract ：
The equigenesis hypothesis suggests that greenery has the potential to reduce health disparities across socioeconomic groups. This is important in high-density urban setting, because greenery can improve human health, but also promotes equitable access to health benefits thus reducing health disparities. However, findings are inconsistent, partly due to the predominance of cross-sectional studies. Moreover, the equigenic effects of street- level greenery, remains underexplored. This longitudinal study examined the effect of street-level greenery on the emotional well-being of older adults. We analyzed 3110 street view images from 1,550 locations in Fuzhou, China, collected in 2014 and 2020. Street-level built environment features were measured using the DeeplabV3 network. Emotional well-being, operationalized as perceptions of pleasantness, was quantitatively evaluated using the Microsoft Trueskill approach to convert the paired comparisons of images into a ranked score. Moderation effects of street-level greenery, were investigated through interactions with educational attainment and economic status, based on individual-level fixed effect models. Our findings revealed that: 1) street-level greenery had the most significant influence on enhancing perceptions of pleasantness; 2) the interaction between street-level greenery and average education years, was positively associated with perceptions of pleasantness, while a negative interaction was observed with economic status. These results suggest that while street- level greenery may mitigate income-related disparities, it could accelerate education-related disparities in emotional well-being among older adults. This study offers new insights into the equigenesis hypothesis through a longitudinal lens, demonstrating that street-level greenery may not uniformly improve mental health equity among older adults in Chinese cities.

Abstract ：
As urbanization progresses, efficient land resource management is essential for sustainable urban development. While existing studies emphasize the positive impact of urban economic linkages (UEL) on urban land-use efficiency (ULUE), they often assume equal partnerships, overlooking the asymmetric nature of UEL. This study uses a modified gravity model and super-efficiency SBM model to explore the impact of unequal economic linkages within the UEL network on ULUE across 284 Chinese cities from 2002 to 2021. The findings reveal that ULUE increased until 2017 but declined thereafter. Cities in the southeastern coastal regions show higher ULUE, while those in the northeast exhibit lower efficiency. The Tobit model analysis indicates that cities with greater dominance in the UEL network tend to have higher ULUE, while those more dependent on external economies experience lower ULUE. Robustness checks confirm the stability of these results across different model specifications. The study underscores the importance of fostering more balanced economic linkages and advocates for policy reforms aimed at enhancing urban economic integration to improve ULUE across cities.

Abstract ：
Numerous studies have suggested that the perceived built environment is shaped by the objective built environment and influences human physical activity. However, the empirical examination of this pathway remains scant. Addressing this gap, our study investigates whether the built environment affects leisure-time physical activity through its impact on the perceived built environment, utilizing data collected from 760 residents in Fuzhou, China. Structural Equation Modeling results reveal a modest correlation between objective and perceived built environment elements, with the objective built environment being a stronger predictor of leisure-time physical activity. Notably, perceived recreational facilities significantly mediate the relationship between objective recreational facilities and leisure-time physical activity, accounting for 15% of the variance in physical activity due to objective recreational facilities. This mediation effect is consistent across subpopulations, irrespective of residential self-selection biases. These results highlight the imperative for urban planning and policy to extend beyond mere spatial allocation of amenities to enhancing both the actual and perceived accessibility of these facilities, thus underlining the study's profound implications for public health and urban development strategies.

Abstract ：
BackgroundIt remains unknown whether good neighbourhood perception can enhance the benefits of favourable built environment to physical activity. Moreover, the moderation pattern is less understood in developing countries.ObjectivesThis work aims to examine the moderation effects of perceived neighbourhood safety and aesthetics on the relationship between built environment and time for recreational walking.MethodsWe performed the examination using a sample of 760 residents in Fuzhou City, China. The Negative Binomial Regression Model was developed to examine the moderation roles of neighbourhood safety and aesthetics on the impact of built environment, adjusting for the effects of location, socioeconomic, personal preferences and social environment factors. Moreover, two sensitivity analyses were performed to test whether the moderators found are robust to the control of residential self-selection, and differential measures of conceptually-comparable aspects of built environment.ResultsWe found stronger associations of time for recreational walking with road density and proportion of parks and squares POIs for residents with high perception of neighbourhood safety, compared to those with low perception of neighbourhood safety. There was a greater effect of the proportion of parks and squares POIs, when perceived aesthetics was high than when perceived aesthetics was low. The findings of neighbourhood safety and aesthetics as moderator, were robust in the two sensitivity analyses. No significant moderation effect was found for land use diversity.ConclusionsHigh perceived neighbourhood safety can magnify the positive effects of road connectivity and accessibility to parks and squares. Neighbourhood aesthetics positively moderates the association of time for recreational walking with accessibility to parks and squares. The findings emphasize the need to consider safety- and aesthetics-specific differences in estimates of built environment effects. Improvements in neighbourhood safety and aesthetics are key to effective interventions in built environment to better promote physical activity.

Abstract ：
Background: Cycling is known to be beneficial for human health. Studies have suggested significant associations of physical activity with macroscale built environments and streetscapes. However, whether good streetscapes can amplify the benefits of a favorable built environment on physical activity remains unknown. Objective: This study examines whether streetscape perceptions can modify the associations between accessibility, land use mix, and bike-sharing use. Methods: This cross-sectional study used data from 18,019,266 bike-sharing orders during weekends in Shanghai, China. A 500 x 500 m grid was selected as the analysis unit to allocate data. Bike-sharing use was defined as the number of bike-sharing origins. Street view images and a human-machine adversarial scoring framework were combined to evaluate lively, safety, and wealthy perceptions. Negative binomial regression was developed to examine the independent effects of the three perceptual factors in both the univariate model and fully adjusted model, controlling for population density, average building height, distance to nearest transit, number of bus stations, number of points of interest, distance to the nearest park, and distance to the central business district. The moderation effect was then investigated through the interaction term between streetscape perception and accessibility and land use mix, based on the fully adjusted model. We also tested whether the findings of streetscape moderation effects are robust when examinations are performed at different geographic scales, using a small-sample statistics approach and different operationalizations of land use mix and accessibility. Results: High levels of lively, safety, and wealthy perceptions were correlated with more bike-sharing activities. There were negative effects for the interactions between the land use Herfindahl-Hirschman index with the lively perception (beta=-0.63;P=.01) and safety perception (beta=-0.52; P=.001). The interaction between the lively perception and road intersection density was positively associated with the number of bike-sharing uses (beta=0.43; P=.08). Among these, the lively perception showed the greatest independent effect (beta=1.29; P<.001), followed by the safety perception (beta=1.22; P=.001) and wealthy perception(beta=0.72; P=.001). The findings were robust in the three sensitivity analyses. Conclusions: A safer and livelier streetscape can enhance the benefits of land use mix in promoting bike-sharing use, with a safer streetscape also intensifying the effect of accessibility. Interventions focused on streetscape perceptions can encourage cycling behavior and enhance the benefits of accessibility and land use mix. This study also contributes to the literature on potential moderators of built environment healthy behavior associations from the perspective of microscale environmental perceptions.

Abstract ：
The association between built environment and physical activity has been recognized. However, how and to what extent microscale streetscapes are related to running activity remains underexplored, partly due to the lack of running data in large urban areas. Moreover, few studies have examined the interactive effects of macroscale built environment and microscale streetscapes. This study examines the main and interactive effects of the two-level environments on running intensity, using 9.73 million fitness tracker data from Keep in Shanghai, China. Results of spatial error model showed that: 1) the explanatory power of microscale streetscapes was higher than that of macroscale built environment with R2 of 0.245 and 0.240, respectively, which is different from the prior finding that R2 is greater for macroscale built environment than for microscale streetscape; 2) sky and green view indexes were positively associated with running intensity, whereas visual crowdedness had a negative effect; 3) there were negative interactions of land use Herfindahl-Hirschman index with sky and green view indexes, while a positive interaction was observed for visual crowdedness. To conclude, greener, more open and less visually crowded streetscapes, can promote running behavior and enhance the benefits of land use mix as well. The findings highlight the importance of streetscapes in promoting running behavior, instead of a supplement to macroscale built environment.

Abstract ：
With the prevalence of stroke rising due to both aging societies and more people getting strokes at a younger age, a comprehensive investigation into the relationship between urban characteristics and age-specific stroke mortality for the development of a healthy built environment is necessary. Specifically, assessment of various dimensions of urban characteristics (e.g. short-term environmental change, long-term environmental conditions) is needed for healthy built environment designs and protocols. A multifactorial assessment was conducted to evaluate associations between environmental and sociodemographic characteristics with age-stroke mortality in Hong Kong. We found that short-term (and temporally varying) daily PM10, older age and being female were more strongly associated with all types of stroke deaths compared to all-cause deaths in general. Colder days, being employed and being married were more strongly associated with hemorrhagic stroke deaths in general. Long-term (and spatially varying) regional-level air pollution were more strongly associated with non-hemorrhagic stroke deaths in general. These associations varied by age. Employment (manual workers) and low education were risk factors for stroke mortality at younger ages (age <65). Greenness and open space did not have a significant association with stroke mortality. Since a significant connection was expected, this leads to questions about the health-inducing efficacy of Hong Kong's compact open spaces (natural greenery being limited to steep slopes, and extensive impervious surfaces on public open spaces). In conclusion, urban plans and designs for stroke mortality prevention should implement age specific health care to neighborhoods with particular population segments.

Abstract ：
Background Many studies have reported the effects of PM2.5 and PM10 on human health, however, it remains unclear whether particular matter with finer particle size has a greater effect. Objectives This work aims to examine the varying associations of the incidence rate of female lung cancer with PM1, PM2.5 and PM10 in 436 Chinese cancer registries between 2014 and 2016. Methods The effects of PM1, PM2.5 and PM10 were estimated through three regression models, respectively. Mode l only included particular matter, while Model 2 and Model 3 further controlled for time and location factors, and socioeconomic covariates, respectively. Moreover, two sensitivity analyses were performed to investigate the robustness of three particular matte effects. Then, we examined the modifying role of urban-rural division on the effects of PM1, PM2.5 and PM10, respectively. Results The change in the incidence rate of female lung cancer relative to its mean was 5.98% (95% CI: 3.40, 8.56%) for PM1, which was larger than the values of PM2.5 and PM10 at 3.75% (95% CI: 2.33, 5.17%) and 1.57% (95% CI: 0.73, 2.41%), respectively. The effects of three particular matters were not sensitive in the two sensitivity analyses. Moreover, urban-rural division positively modified the associations of the incidence rate of female lung cancer with PM1, PM2.5 and PM10. Conclusions The effect on the incidence rate of female lung cancer was greater for PM1, followed by PM2.5 and PM10. There were positive modifying roles of urban-rural division on the effects of three particular matters. The finding supports the argument that finer particular matters are more harmful to human health, and also highlights the great significance to develop guidelines for PM1 control and prevention in Chinese setting.
