![]() Urban planners can intuitively obtain the characteristics of carbon emissions within the research scope ( 7, 8), identify the hot and cold spots of carbon emissions, and then formulate targeted low-carbon and health-oriented urban planning scheme ( 9, 10). The carbon emissions map is an important basis for urban planning to reduce carbon emissions. Therefore, urban planning is a key technology for reducing carbon emissions and promoting public health. Compared to a comfortable temperature of 23☌, each 1☌ increase in temperature was associated with a predicted 0.2% increase in psychological stress ( 6). In addition, urban planning can reduce energy carbon emissions by 12% by adjusting land use structure ( 5). Air pollution is one of the most important causes of global human health risks ( 4). Studies have shown that urban areas account for 76% of primary energy consumption, resulting in carbon emissions and ambient air pollution ( 3). Urban planning can improve energy efficiency, reduce carbon emissions, mitigate the heat island effect and promote public health through rational allocation of land resources ( 1, 2). Urban planning is an important means to control carbon emissions. The results achieved can better help governments develop different carbon reduction strategies, mitigate the heat island effect, and support low-carbon and health-oriented urban planning. The proportion of land patches is an important factor in determining carbon emissions, and the adjustment of industrial structure is the most critical factor in reducing carbon emissions. ![]() The Moran's I of land patch level carbon emissions was 0.138, showing a significant positive spatial correlation. Forest land carbon absorption accounted for 98.56%, mainly concentrated in the peripheral streets away from urban areas. Among them, industrial land accounted for 70.16% of carbon emissions, mainly concentrated in three industrial towns. The vector maps of Zhangdian City show that in 2021, the total carbon emissions and carbon absorptions were 4.76 × 10 9kg and 4.28 × 10 6kg respectively. The results show that the vector carbon emissions map can help identify the key carbon reduction land patches and the impact factors of carbon emissions. In addition, the differences between different streets were analyzed, and the carbon emissions ratio of the land patch was compared. The vector maps and spatial autocorrelation of carbon emissions in Zhangdian City, China were explored using multi-source data. In this study, a vectorization method for spatial allocation of carbon emissions at the land patch level was proposed. ![]() However, little research has focused on carbon emissions maps at the land patch level, which makes poor integration with small and medium-sized urban planning based on land patches. 3Zibo Urban Planning Design Institute Co., Ltd., Zibo, ChinaĪn accurate carbon emissions map is of great significance for urban planning to reduce carbon emissions, mitigate the heat island effect, and avoid the impact of high temperatures on human health.2School of Architectural Engineering, Tongling University, Tongling, China.1School of Architecture and Urban Planning, Shandong Jianzhu University, Jinan, China.Xiaoping Zhang 1 *, Qinghua Liao 2 *, Hu Zhao 1 and Peng Li 3
