Therefore, identifying methods of using limited urban spaces to alleviate heat islands has become an urgent issue. In this study, we assessed the spatiotemporal evolution of urban heat islands within the central urban area of Fuzhou City, China from 2010 to 2019. This assessment was based on a morphological spatial pattern analysis (MSPA) model and an urban thermal environment spatial network constructed using the minimum cumulative resistance (MCR) model. Optimization measures for the spatial network were proposed to provide a theoretical basis for alleviating urban heat islands. The results show that the heat island area within the study area gradually increased while that of urban cold island area gradually decreased. The core area was the largest of the urban heat island patch landscape elements with a significant impact on other landscape elements, and represented an important factor underlying urban heat island network stability. The thermal environment network revealed a total of 197 thermal environment corridors and 93 heat island sources. These locations were then optimized according to the current land use, which maximized the potential of 1599.83 ha. Optimization based on current land use led to an increase in climate resilience, with effective measures showing reduction in thermal environment spatial network structure and function, contributing to the mitigation of urban heat island. These findings support the use of current land use patterns during urban heat island mitigation measure planning, thus providing an important reference basis for alleviating urban heat island effects.</p>","PeriodicalId":55258,"journal":{"name":"Chinese Geographical Science","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2024-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142183832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Built upon the new economic geography and city networks theory, this paper develops a methodological framework that focuses on the analysis of city network evolution characteristics of smart industry. Particularly, a conceptual model of smart industry enterprise-industry-city is proposed and then applied to a case study of smart industry in the Yangtze River Delta Region, China. Using enterprise supplier-customer data, a city network of smart industry is constructed and subsequently analyzed with the proposed model. Findings indicate that the smart industry network in Yangtze River Delta Region exhibits a hierarchical structure and the expansion of the network presents a small-world network characteristic.

The existing spatial mismatch between rural elderly service facilities and population distribution in China aggravates the imbalance of facility resource space, how to improve the accuracy of demand and supply results and better measuring the spatial fairness of elderly service is significant to realize the optimal allocation of rural elderly service. Based on the above, this study pays attention to the refined needs of the elderly population, and focuses on the spatial equity of the rural elderly facilities, to make up for the short boards of the basic public services in the countryside and realize the all-round rural revitalization. This study takes Huanxian County in the hilly loess area of Longdong, China as an example and explores the spatial equity of rural elderly services by using the Urban Spatial Network Analysis (UNA) to measure the accessible quantity and supply capacity of elderly services. The results found that there were 553 rural eldercare service facilities in Huanxian County, including 285 eldercare facilities and 268 medical and health facilities, and the spatial distribution is characterized by a southward shift in the east and uneven regional distribution. Overall, the supply capacity of rural pension services was generally good, with the township center as the gathering point and spreading out in a faceted manner, with nearby townships forming a contiguous area; however, there were strong contrasts and obvious differences in the strength of supply capacity. However, the spatial equity of rural eldercare service was poor. In 42.05% of the elderly population grid cells, eldercare service spatial equity was extremely low. The spatial distribution also presented a northern preference over the southern, a western preference over the eastern, and a concentration along the highway. The study explored the realization of spatial equity in the optimal allocation of rural elderly services based on paying attention to the refined needs of the rural elderly population, a vulnerable group, to provide a reference for solving the shortcomings of basic public services in rural areas. The fair allocation of rural elderly services demands that the spatial optimization of facility layout be organically coordinated with policy, management, and post-maintenance, and all elements in the rural territorial system be fully mobilized to achieve the basic guarantee of China’s rural elderly problems.</p>","PeriodicalId":55258,"journal":{"name":"Chinese Geographical Science","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2024-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142183795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a super megacity in western China, Chengdu’s rapid urbanization has driven the evolution of U-S-R spaces, resulting in a sequential structure. To promote the high-quality spatial development of urban-rural region in a structured and efficient manner, it is essential to conduct a scientific examination of the multidimensional interconnection within the U-S-RTZ framework. By proposing a novel identification method of U-S-RTZ and taking Chengdu, China as a case study, grounded in a blender of natural and humanistic factors, this study quantitatively delineated and explored the spatial evolutions of U-S-RTZ and stated the optimization orientation and sustainable development strategies of the production-living-ecological spaces along the U-S-R gradients. The results show that: 1) it is suitable for the quantitative analysis of U-S-RTZ by established three-dimensional identification system in this study. 2) In 1990–2020, the urban-suburban transition zones (U-STZ) in Chengdu have continuously undergone a substantial increase, and the scale of the suburban-rural transition zones (S-RTZ) has continued to expand slightly, while the space of rural-ecological transition zones (R-ETZ) has noticeably compressed. 3) The landuse dynamics within U-S-RTZ has gradually increased in 1990–2020. The main direction of landuse transition was from farmland to construction land or woodlands, with the expansion of construction land being the most significant. 4) R-ETZ primarily focus on ecological functions, and there is a trade-off relationship between the production-ecological function within the S-RTZ, and in the U-STZ, production-living composite functions are prioritized.

Accurately identifying the differences in spatial characteristics and influencing factors of each type, is essential for creating urban and rural B&amp;B agglomeration areas. This study used density-based spatial clustering of applications with noise (DBSCAN) and the multi-scale geographically weighted regression (MGWR) model to explore similarities and differences in the spatial distribution patterns and influencing factors for urban and rural B&amp;Bs on the Jiaodong Peninsula of China from 2010 to 2022. The results showed that: 1) both urban and rural B&amp;Bs in Jiaodong Peninsula went through three stages: a slow start from 2010 to 2015, rapid development from 2015 to 2019, and hindered development from 2019 to 2022. However, urban B&amp;Bs demonstrated a higher development speed and agglomeration intensity, leading to an increasingly evident trend of uneven development between the two sectors. 2) The clustering scale of both urban and rural B&amp;Bs continued to expand in terms of quantity and volume. Urban B&amp;B clusters characterized by a limited number, but a higher likelihood of transitioning from low-level to high-level clusters. While the number of rural B&amp;B clusters steadily increased over time, their clustering scale was comparatively lower than that of urban B&amp;Bs, and they lacked the presence of high-level clustering. 3) In terms of development direction, urban B&amp;B clusters exhibited a relatively stable pattern and evolved into high-level clustering centers within the main urban areas. Conversely, rural B&amp;Bs exhibited a more pronounced spatial diffusion effect, with clusters showing a trend of multi-center development along the coastline. 4) Transport emerged as a common influencing factor for both urban and rural B&amp;Bs, with the density of road network having the strongest explanatory power for their spatial distribution. In terms of differences, population agglomeration had a positive impact on the distribution of urban B&amp;Bs and a negative effect on the distribution of rural B&amp;Bs.

In order to develop a comprehensive risk assessment method considering the superimposed effects of these two factors and analyze risk for mangroves in Dongzhaigang, Hainan Island, China, we used observational and climate model data to assess the risks to mangroves under low, intermediate, and very high greenhouse gas (GHG) emission scenarios (such as SSP1-2.6, SSP2-4.5, and SSP5-8.5) in 2030, 2050, and 2100, and compiled a risk assessment scheme for mangroves in Dongzhaigang, China. The results showed that the combined risks from SLR and TCs will continue to rise; however, SLRs will increase in intensity, and TCs will decrease. The comprehensive risk of the Dongzhaigang mangroves posed by climate change will remain low under SSP1-2.6 and SSP2-4.5 scenarios by 2030, but it will increase substantially by 2100. While under SSP5-8.5 scenario, the risks to mangroves in Dongzhaigang are projected to increase considerably by 2050, and approximately 68.8% of mangroves will be at very high risk by 2100.
