“…Urbanization not only increases urban energy consumption, but also impacts the urban landscape changing significantly by converting land cover from green cover to grey cover, i.e., impervious surfaces cover (ISC) ( Yu et al, 2014 , Silva et al, 2018 , Yu et al, 2019 , Zou et al, 2021 ). Another side-effect of urbanization is the excessive heat release due to human activities, which has a major role in the formation and increase in surface urban heat island intensity (SUHII) ( Firozjaei et al, 2018 , Zhou and Chen, 2018 , Fahed et al, 2020 , Liu et al, 2020 , Nadizadeh Shorabeh et al, 2020 , Yuan et al, 2020a , Tepanosyan et al, 2021 ).…”

“…Usually, the thermal environment of a city is affected by various urban activities, and the urban land carrying urban activities or functions exhibits a notable difference in thermal environment. Generally, production and residential areas are heat effect areas, and ecological lands such as water regions and green land are the main cold effect areas, as seen in the conclusions drawn from previous studies on the relationship between urban land and the thermal environment [24,[109][110][111][112][113][114][115][116]. In Xuzhou, there is an obvious heat island effect.…”

Urban heat islands (UHIs) constitute an important ecological problem in cities. Ecological space has a positive effect on UHI mitigation, which can be effectively organized in the form of ecological networks. In this study, the framework for structural UHI improvement based on ecological networks considering the source-corridor model is proposed to examine the spatial threshold of the thermal effect of ecological network factors. Additionally, the cooling mechanism of each constituent element in the ecological network context is further explored. The results demonstrate that (1) an obvious cold and heat island spatial aggregation distribution exists in the Xuzhou main urban area, and land of the same land use type exhibits the dual thermal environmental properties of cold and heat islands through its spatial distribution and characteristics. Ecological space is the main bearing area of cold islands. (2) The ecological network in the main urban area of Xuzhou city occurs at a moderately complex level, and the overall network efficiency is acceptable; the network connectivity is low, while the network loop distribution is uneven. (3) Ecological networks represent an effective spatial means to improve overall UHI patterns. The ecological source area cooling threshold is 300 m, and the optimal threshold is 100 m, while the ecological corridor width threshold is 500 m and 60 m, respectively. (4) Within the optimal threshold in the context of ecological networks, the temperature of ecological sources in category G land is influenced by NDBI and FVC; ecological corridors are mainly influenced by NDBI. The results can provide a quantitative basis for urban ecological network planning considering UHI improvement and a reference for urban thermal environment research within different ecological substrates and planning and control systems in other countries and regions worldwide.

“…Abundant studies have been conducted to investigate the UHI in different scales and different regions. Generally, these studies mainly focus on the following aspects: (1) the spatial and temporal evolution of UHI [4][5][6][7][8][9];…”

“…Remote sensing is a popular way to study the surface UHI effect on a larger scale because it is easy to obtain data covering a larger region [20], but the observed images capture the composite effect with all the influencing factors. Although some studies have investigated the driving factors of UHI qualitatively [5,15]; still, it is hard to detach the effect of one aspect quantificationally based on the remotely sensed data. Meanwhile, the model simulation method, driven by the initial conditions and forcing conditions, can simulate the results using a numerical model with the built-in mechanism of the of physics, biology, and chemistry and their progress toward understanding the Earth [21][22][23][24].…”

With the rapid process of urbanization, the urban heat island (UHI), the phenomenon where urban regions become hotter than their surroundings, is increasingly aggravated. The UHI is affected by multiple factors overall. However, it is difficult to dissociate the effect of one aspect by widely used approaches such as the remote-sensing-based method. To qualify the response of surface UHI to the land use and land cover (LULC) changes, this study took the numerical land model named u-HRLDAS (urbanized high-resolution land data assimilation system) as the modeling tool to investigate the effect of LULC changes on the UHI from 1980 to 2013 in Wuhan city, China. Firstly, the simulation accuracy of the model was improved, and the summer urban heat environment was simulated for the summer of 2013. Secondly, taking the simulation in 2013 as the control case (CNTL), the LULC in 1980, 1990, and 2000 were replaced by the LULC while the other conditions kept the same as the CNTL to explore the effect of LULC on UHI. The results indicate that the proper configuration of the modeling setup and accurate surface input data are considered important for the simulated results of the u-HRLDAS. The response intensity of UHI to LULC changes after 2000 was stronger than that of before 2000. From the spatial perspective, the part that had the strongest response intensity of land surface temperature to LULC changes was the region between the third ring road and the inner ring road of Wuhan. This study can provide a reference for cognizing the urban heat environment and guide policy making for urban development.
