“…Global air and land temperatures have shown a long-term warming trend since preindustrial times [1]. Regions with warmer temperatures suffer from stronger urban heat islands (UHIs) [2]. UHI, a phenomenon in which a region's air temperature or land surface temperature (LST) is typically greater than that of its surrounding areas [3], is directly linked to anthropomorphic activities, such as the direct heat emissions of fuel combustion and electricity consumption [4,5].…”

Global warming and the urban heat island (UHI) phenomenon have significant impacts on human activities, against which it is necessary to develop effective coping strategies. Based on the local climate zone (LCZ) system, this study used the land-cover and surface temperature data on the Chang–Zhu–Tan (CZT) urban agglomeration in China in 2006, 2010, 2016, and 2020 to analyze the impact of climate change on the land surface temperature (LST) under different land-cover types. The results illustrate that the LCZ map generated on the basis of the improved World Urban Database and Access Portal Tools (WUDAPT) is more accurate and efficient than the traditional method. The accuracy is increased by more than 15%. From 2006 to 2020, the main built-up types in the CZT urban agglomeration were the sparsely built, the large low-rise, and the compact mid-rise types. The low-plant type represents the most significant proportion of the natural types, followed by the water and the dense-tree types. The built-up types in the CZT urban agglomeration tend to be the high-rise, dense, and industrial types. Urban construction land is taken mainly from the sparsely built type of land. The average LST of the large low-rise and heavy-industry zones is significantly higher than the average LST of the three cities. The average LST values for the water and dense-tree zones are significantly lower than the other average LST values. The LST is stable in each LCZ, showing little correlation with the size of the LCZ area. Compact low-rise land use is ineffective against climate warming and inhibits economic growth. Compact high-rise and open high-rise land can not only effectively deal with climate warming but can also significantly stimulate economic growth. This paper helps us to understand the effect of land cover on climate warming and the economic benefits of LCZs in the CZT urban agglomeration and provides strategies to optimize the use of land resources.

“…The urban heat island effect is widely observed around the world, causing impacts on climate, health and energy in cities. It was found that the intensity of the urban heat island largely depends on the background climate and the properties of the urban land cover (Ziyan Zhang 2022).…”

The ubiquitous process of urbanization leads to the expected trend of population growth that will live on the territory of urban space. The image of urban organization of life leads to an increase in anthropogenic impact on the environment and a decrease in the level of interaction with natural resources. Population growth, or rather an increase in population density within an urban area that does not correspond to quantitative indicators, leads to a change in climatic indicators, which will subsequently affect the quality of life of citizens. The purpose of this scientific study was to identify green areas indicating the coverage of the urban area based on the definition of heat islands and classification by land cover based on satellite images. The scientific significance of the study was justified by the trend aimed at improving urban spaces and improving the quality of life of urban residents. The research methodology consisted in processing satellite images for further reclassification according to generally accepted standards, taking into account the individual indicators of the city of Almaty. The main result of the study was the identification of the zones most unsuitable for the quality of life, and the conclusion was recommendations for improving the environmental situation based on surface temperature indicators that allow identifying heat islands associated with a low quality indicator of the standard of living within the city of Almaty. The value of the research was aimed at developing theoretical theses for subsequent implementation in potential projects to improve the quality of life of residents of Almaty.
