The relative contributions of climate variables and vegetation greening to ETa were estimated with numerical experiments. The results show that the average ETa in the entire basin increased at a rate of 1.16 mm year\u22122 from 1980 to 2012 (36.7% of the area met the 95% significance level). Vegetation greening contributed 54.1% of the annual ETa trend, slightly higher than that of climate change. The contributions of air temperature, precipitation and the LAI were positive, whereas contributions of solar radiation and vapor pressure were negative. The effects of water supply and energy availability were equivalent on the variation of ETa throughout most of the basin, except the upper reach and downstream Mekong Delta. In the upper reach, climate warming played a critical role in the ETa variability, while the warming effect was offset by reduced solar radiation in the Mekong Delta (an energy-limited region). For the entire basin, the available water resources showed an increasing trend due to intensified precipitation; however, in downstream areas, additional pressure on available water resources is exerted due to cropland expansion with enhanced agricultural water consumption. The results provide scientific basis for practices of integrated catchment management and water resources allocation.<\/jats:p>","DOI":"10.3390\/rs13020303","type":"journal-article","created":{"date-parts":[[2021,1,20]],"date-time":"2021-01-20T03:34:25Z","timestamp":1611113665000},"page":"303","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Attribution of Long-Term Evapotranspiration Trends in the Mekong River Basin with a Remote Sensing-Based Process Model"],"prefix":"10.3390","volume":"13","author":[{"given":"Shi","family":"Hu","sequence":"first","affiliation":[{"name":"Key Laboratory of Water Cycle &amp; Related Land Surface Processes, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China"}]},{"given":"Xingguo","family":"Mo","sequence":"additional","affiliation":[{"name":"Key Laboratory of Water Cycle &amp; Related Land Surface Processes, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China"},{"name":"College of Resources and Environment\/SDC College, University of Chinese Academy of Sciences, Beijing 101407, China"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"864","DOI":"10.1007\/s13280-013-0424-4","article-title":"The Flood Pulse as the Underlying Driver of Vegetation in the Largest Wetland and Fishery of the Mekong Basin","volume":"42","author":"Arias","year":"2013","journal-title":"Ambio"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"14026","DOI":"10.1088\/1748-9326\/7\/1\/014026","article-title":"Global evapotranspiration over the past three decades: Estimation based on the water balance equation combined with empirical models","volume":"7","author":"Zeng","year":"2012","journal-title":"Environ.
