Poyang Lake is China\u2019s largest freshwater lake with complex hydrological relationships and unique rhythmic changes. There is no systematic understanding of the relationship between lake watershed area and river\u2013lake connectivity. In this study, using remote sensing imagery, hydrological data, meteorological data, and land use surveys, we investigated changes in the Poyang Lake water area from 1977\u20132021. In addition, we examined the relationship between the lake water area and potential impact factors and analyzed the influence of river\u2013lake interactions on the lake water area. The results showed that the water area of Poyang Lake decreased during the study period. River runoff and sediment load changes in the Poyang Lake basin are the main factors affecting the lake water area. Additionally, the Three Gorges Dam water impoundment situated in the upper reaches of the Yangtze River weakened and eliminated the block and reverse flow of the Yangtze River into the Poyang Lake, causing the water area to decrease toward the end of the flood season in 2005 and in the dry season in 2003. Changes in the lakebed elevation caused by sedimentation and anthropogenic activities have also accelerated the shrinkage of the water area. Overall, the results of this study indicate that variations in the river\u2013lake interactions are the primary cause of the significant changes observed in the Poyang Lake water area in the last five decades.<\/jats:p>","DOI":"10.3390\/rs15030600","type":"journal-article","created":{"date-parts":[[2023,1,19]],"date-time":"2023-01-19T05:50:20Z","timestamp":1674107420000},"page":"600","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Water Area Variation and River\u2013Lake Interactions in the Poyang Lake from 1977\u20132021"],"prefix":"10.3390","volume":"15","author":[{"given":"Biqing","family":"Tian","sequence":"first","affiliation":[{"name":"Regional Soil and Water Conservation and Environmental Effects Research Department, Institute of Soil and Water Conservation, Northwest A&F University, Xianyang 712100, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4723-4256","authenticated-orcid":false,"given":"Peng","family":"Gao","sequence":"additional","affiliation":[{"name":"Regional Soil and Water Conservation and Environmental Effects Research Department, Institute of Soil and Water Conservation, Northwest A&F University, Xianyang 712100, China"},{"name":"Institute of Soil and Water Conservation, Chinese Academy of Sciences and Ministry of Water Resources, Xianyang 712100, China"}]},{"given":"Xingmin","family":"Mu","sequence":"additional","affiliation":[{"name":"Regional Soil and Water Conservation and Environmental Effects Research Department, Institute of Soil and Water Conservation, Northwest A&F University, Xianyang 712100, China"},{"name":"Institute of Soil and Water Conservation, Chinese Academy of Sciences and Ministry of Water Resources, Xianyang 712100, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4233-9403","authenticated-orcid":false,"given":"Guangju","family":"Zhao","sequence":"additional","affiliation":[{"name":"Regional Soil and Water Conservation and Environmental Effects Research Department, Institute of Soil and Water Conservation, Northwest A&F University, Xianyang 712100, China"},{"name":"Institute of Soil and Water Conservation, Chinese Academy of Sciences and Ministry of Water Resources, Xianyang 712100, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1360","DOI":"10.18307\/2020.0511","article-title":"Lake Hydrology in China: Advances and Prospects","volume":"32","author":"Zhang","year":"2020","journal-title":"J.
