Not only can increasing urban tree canopy (UTC) improve sustainable city development, but it can also effectively promote the quality of life for residents; however, the uneven spatial distribution of UTC can also bring about social justice problems. Currently, there are few studies related to the justice of UTC distribution in China. Based on this, the paper adopts object-oriented image classification technology to interpret and extract UTC data from satellite images, and it uses house price to explore the justice of the spatial distribution of UTC in the main urban area of Guangzhou from the perspective of environmental justice by ANOVA, Pearson correlation coefficient, and bivariate local spatial autocorrelation. The results show that: (1) There is a significant positive correlation between UTC and house price in the main urban area of Guangzhou, and there are regional differences in the distribution of UTC, with the UTC in the \u201cvery high\u201d house price group being significantly higher than that in other groups. (2) The spatial clustering of UTC and house price in the main urban area of Guangzhou is found to be \u201clow-low\u201d and \u201chigh-high\u201d; thus, it can be concluded that the spatial distribution of UTC in the main urban area of Guangzhou is uneven. This is an environmental injustice, as the areas with low UTC are spatially clustered in old residential areas, while the areas with high UTC are spatially clustered in commercial housing estates with high house prices. The study shows that urban tree planting should not only focus on quantitative improvement but also on equitable spatial layouts to promote social equity and justice thereby improving the urban ecological environment and promoting healthy urban development.<\/jats:p>","DOI":"10.3390\/ijerph20054050","type":"journal-article","created":{"date-parts":[[2023,2,24]],"date-time":"2023-02-24T03:57:35Z","timestamp":1677211055000},"page":"4050","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Urban Tree Canopy and Environmental Justice: Examining the Distributional Equity of Urban Tree Canopy in Guangzhou, China"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-7226-2223","authenticated-orcid":false,"given":"Yutian","family":"Zhuang","sequence":"first","affiliation":[{"name":"School of Architecture and Urban Planning, Guangdong University of Technology, Guangzhou 510090, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5256-0638","authenticated-orcid":false,"given":"Dixiang","family":"Xie","sequence":"additional","affiliation":[{"name":"School of Architecture and Urban Planning, Guangdong University of Technology, Guangzhou 510090, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xijun","family":"Yu","sequence":"additional","affiliation":[{"name":"South China Institute for Environmental Science, Ministry of Ecology and Environment, Guangzhou 510655, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2078","DOI":"10.1016\/j.envpol.2011.01.010","article-title":"Urban forests and pollution mitigation: Analyzing ecosystem services and disservices","volume":"159","author":"Escobedo","year":"2011","journal-title":"Environ.
