This study used Landsat data to study the impact of landscape patterns on urban heat islands (UHIs) and temporal-spatial change characteristics. In addition, spatial correlation analysis was employed to detect the relationships between land surface temperature (LST) and landscape patterns. The results showed that the impervious surfaces landscape area increased significantly, and the Woodland landscape area increased. However, the bare land, cropland, and water body area decreased. The cohesion of cropland and woodland landscape in the suburb decreased, and there was a high degree of fragmentation. The difference between the contributions of the central city and suburbs to the whole region is narrowing, and the expansion of urban heat islands is shifting from the central city to the suburbs. The percentage of landscape index (PLAND) and the patch cohesion index (COHESION) of woodland, water body, and cropland were negatively correlated with LST. Meanwhile, the PLAND and COHESION of impervious surface and bare land were positively correlated with LST, and the splitting index (SPLIT) was the opposite of the PLAND and COHESION. The fragmentation of impervious surfaces and bare land landscapes reduces the UHI effect. Based on these results, countermeasures to mitigate the heat island effect are proposed. These measures will play an essential role in improving urban ecology and the environmental quality of human settlements.<\/jats:p>","DOI":"10.3390\/ijerph192013297","type":"journal-article","created":{"date-parts":[[2022,10,17]],"date-time":"2022-10-17T00:04:55Z","timestamp":1665965095000},"page":"13297","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Analysis of the Impact of Landscape Patterns on Urban Heat Islands: A Case Study of Chengdu, China"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3782-9790","authenticated-orcid":false,"given":"Zishu","family":"Sun","sequence":"first","affiliation":[{"name":"Park Urban Research Center, Chengdu University of Technology, Chengdu 610059, China"},{"name":"School of Foreign Studies, Chengdu Neusoft University, Chengdu 611844, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhigang","family":"Li","sequence":"additional","affiliation":[{"name":"Park Urban Research Center, Chengdu University of Technology, Chengdu 610059, China"},{"name":"College of Management Science, Chengdu University of Technology, Chengdu 610059, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0523-3981","authenticated-orcid":false,"given":"Jialong","family":"Zhong","sequence":"additional","affiliation":[{"name":"Park Urban Research Center, Chengdu University of Technology, Chengdu 610059, China"},{"name":"College of Management Science, Chengdu University of Technology, Chengdu 610059, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1889","DOI":"10.1177\/00420980211017817","article-title":"Urban scaling in rapidly urbanising China","volume":"59","author":"Lei","year":"2021","journal-title":"Urban Stud."},{"key":"ref_2","unstructured":"United Nations (2019, January 01).
