Utilizing taxi GPS data from 2016, 2018, 2020, and 2022, we assessed the carbon emission levels of taxis in Xi'an and matched the results to a grid using map matching. The K-means algorithm was used to analyze the spatial clustering and spatial-temporal distribution of carbon emissions, and the gradient boosting iterative decision tree model （GBDT） was used to explore the influence of built environments on carbon emissions. The results showed that： Weekend carbon emissions were greater than weekday emissions in all years, and the difference between weekend and weekday carbon emissions decreased year by year with the increase in the proportion of electric cabs. The overall weekend carbon emissions in 2022 decreased by approximately 56%, and the overall weekday carbon emissions decreased by approximately 40% compared to those in 2016. The carbon emission region in Xi'an had experienced an evolution from a region-wide ring-shaped distribution in 2016 to 2022. The evolution process of the ring-shaped distribution of peripheral low-carbon emission regions, partial reticulation of medium-carbon emission regions, and reticulation of high-carbon emission regions. From the importance analysis of built environmental factors, it could be seen that residential land and population density had relatively high importance for carbon emissions in each year. The importance of public facilities land was higher on weekdays than that on weekends, while the importance of leisure and entertainment land was higher on weekends than that on weekdays. This work reveals the spatial and temporal distribution evolution of carbon emissions, which can provide a reference for the control and management of transportation carbon emissions under the mixed traffic state.</p>","PeriodicalId":35937,"journal":{"name":"环境科学","volume":"45 11","pages":"6403-6411"},"PeriodicalIF":0.0,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142772825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is of great significance to conduct regional differentiated carbon governance and promote regional collaborative emission reduction. As a result, this study first constructed a research framework for regional carbon imbalance risk assessment based on carbon budget. Then, the carbon budget was calculated at a grid and county scale taking Henan Province as an example, and its spatio-temporal pattern was discussed. Finally, the regional carbon imbalance risk index was constructed to reveal the temporal and spatial evolution characteristics of carbon imbalance risk in Henan Province. The results showed： ① From 2001 to 2020, the carbon emissions in Henan Province increased from 232 million tons to 586 million tons. Spatially, it exhibited a gradually decreasing distribution pattern from the central areas to the periphery of each city. Carbon absorption showed a slight fluctuating increase trend （117 million-153 million） with a distribution feature of \"higher in the west, lower in the east； higher in the south, lower in the north.\" ② The carbon source/sink ratio in Henan Province showed a characteristic of rapid growth followed by a gradual decline, reaching a peak of 5.14 in 2013. The carbon source/sink value in economically developed areas was significantly higher than that in economically underdeveloped areas. The regional differences in carbon balance transformation were evident, showing an overall \"imbalance-neutralization-imbalance\" trend. ③ During the study period, carbon imbalance risks in Henan Province gradually stabilized, and the number of districts and counties with a carbon imbalance risk index higher than 0.6 was 107 （68.2%） during 2016-2020. The high-risk areas of carbon imbalance mainly expanded from the Zhengzhou metropolitan area to the periphery along major transportation routes. ④ Future efforts should focus on establishing land spatial optimization and differentiated governance strategies, considering varying carbon imbalance risks across regions.

This method followed three steps： First, a meta-analysis was performed to assess the exposure of TrOCs in reclaimed water, and a database of TrOCs exposure （E） was established.
