Previous studies paid special attention to climatic regulations of IAV of ET. However, ignoring the role of landscape characteristics (e.g., vegetation coverage) can introduce great uncertainty in the explanation of ET variance. In this work, the Poyang Lake Basin, which is a typical humid basin in China, was taken as the study area. It has experienced an obvious climate change and revegetation since the 1980s. Here, trends of IAV of ET and their responses to four climatic variables (i.e., air temperature, precipitation, downward shortwave radiation and wind speed) and vegetation coverage were explored from 1983 to 2014. The results show that IAV of ET exhibited contrary trends during the past decades. It significantly (p &lt; 0.05) declined with a significant linear slope of \u22120.52 mm\/year before 2000, and then slightly increased (slope = 0.06 mm\/year, p &gt; 0.05) over the basin, which was generally consistent with the IAV of temperature and radiation. The proposed variables could well capture the change in IAV of ET, while their dominators were different during the two contrasting phases mentioned above. The IAV of radiation and temperature dominated the change of the IAV of ET over 77.82% and 35.14% of the basin, respectively, before and after the turning point. Meanwhile, the rapid increase in vegetation coverage, which was associated with afforestation, significantly (p &lt; 0.05) reduced IAV of ET over about 35% of the study area. The achievements of this study should be beneficial for a sophisticated awareness of responses of intra-annual variability of ET to climate and land cover changes at the basin scale.<\/jats:p>","DOI":"10.3390\/rs14040885","type":"journal-article","created":{"date-parts":[[2022,2,13]],"date-time":"2022-02-13T20:34:45Z","timestamp":1644784485000},"page":"885","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Intra-Annual Variability of Evapotranspiration in Response to Climate and Vegetation Change across the Poyang Lake Basin, China"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7428-1173","authenticated-orcid":false,"given":"Ying","family":"Wang","sequence":"first","affiliation":[{"name":"School of Culture Industry and Tourism Management, Sanjiang University, Nanjing 210012, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8780-927X","authenticated-orcid":false,"given":"Yuanbo","family":"Liu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Watershed Geographic Sciences, Nanjing Institute of Geography and Limnology, Chinese Academy of Sciences, Nanjing 210008, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4067-298X","authenticated-orcid":false,"given":"Jiaxin","family":"Jin","sequence":"additional","affiliation":[{"name":"College of Hydrology and Water Resources, Hohai University, Nanjing 210024, China"},{"name":"National Earth System Science Data Center, National Science & Technology Infrastructure of China, Beijing 100101, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0099-1839","authenticated-orcid":false,"given":"Xingwang","family":"Fan","sequence":"additional","affiliation":[{"name":"Key Laboratory of Watershed Geographic Sciences, Nanjing Institute of Geography and Limnology, Chinese Academy of Sciences, Nanjing 210008, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,2,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"220","DOI":"10.2111\/05-090R1.1","article-title":"Emerging issues in rangeland ecohydrology: Vegetation change and the water cycle","volume":"59","author":"Wilcox","year":"2006","journal-title":"Rangel.
