Temperature condition in urban areas has a substantial impact on the well-being and safety of both residents ecosystems. Green spaces are crucial for mitigating heat impacts, hence, their balanced supply demand is essential. Due to rapid urbanization, Chengdu had significant increase population, which an dynamic changes its green space environment, making it suitable case our study. This study employs high-temperature vulnerability framework classify as entities that regulate thermal environment. classification based analysis ecosystem service demand. The approach creates assessment managing balance between need availability environment regulation spaces. utilizes matching priority index identify places where there imbalances services. Our findings suggest: (1) regulating Chengdu’s defined by three indices: exposure, sensitivity, adaptability. High-demand account relatively small proportion exhibit pattern “global diffusion local concentration”. (2) capacity determined size surface temperature. High-supply mainly located southeastern part city, distribution similar (3) level correspondence varies significantly can be classified into categories: “insufficient high demand”, low “abundant demand”. Out these, 32 units area with shortage supply, while 6 imbalance (4) categorized four intervention levels: I, II, III, IV zones. zone, level, consists two primarily Inner Ring Qingyang, Jinjiang, Cuijiadian, Caotang, Donghu, deemed needing prioritized regulation.

Uncovering the Nexus between Urban Heat Islands and Material Stocks of Built Environment in 335 Chinese Cities

Environmental Science & Technology, Год журнала: 2024, Номер 58(31), С. 13760 - 13771

China's unprecedented rapid urbanization has dramatically reshaped the urban built environment, disrupting thermal balance of cities. This disruption causes heat island (UHI) effect, adversely affecting sustainability and public health. Although studies have highlighted remarkable impacts environment on UHIs, specific effects its various structures components remain unclear. In this study, a multidimensional remote sensing data set was used to quantify atmospheric UHIs across 335 Chinese cities from 1980 2020. conjunction with stocks three end-use sectors material groups, gridded UHI variations were analyzed. The findings reveal that building exert predominant influence in 48% Additionally, extensive use metal inorganic materials increased stress 220 cities, leading an average increase 0.54 °C. effect organic materials, primarily arising mobile sources, is continuously increasing. Overall, study elucidates functional structure composition landscapes highlighting complexities associated load.
