Evapotranspiration　(ET)　is　the　sum　of　soil　or　water　body　evaporation　and　plant　transpiration　from　the　earth　surface　and　ocean　to　the　atmosphere,　and　thus　plays　a　significant　role　in　regulating　carbon　and　water　resource　cycles.　The　time-series　data　set　from　the　remote　sensing　MOIDS　product　(MOD16)　was　used　to　study　the　spatial-temporal　evolution　of　vegetation　evapotranspiration　in　salinized　areas　during　2000–2014　by　analyzing　the　variability,　spatial　patterns　and　Mann-Kendall　(MK)　nonparametric　trends　for　the　time　series.　The　results　indicate　that　inter-annual　and　intra-annual　variations　of　ET　across　various　vegetated　areas　show　seasonal　changes,　with　the　abnormal　months　identified.　The　cultivated　land　displays　a　greater　degree　of　spatial　heterogeneity　and　the　spatial　pattern　of　ET　in　the　area　covered　by　broadleaved　deciduous　forests　corresponds　to　a　higher　ET　rate　and　increased　water　consumption.　A　widespread　decline　of　ET　is　observed　only　in　cultivated　areas.　However,　agricultural　cultivation　doesn＇t　worsen　water　shortage　and　soil　salinization　problems　in　the　region,　and　water　shortage　problems　are　worsening　for　other　vegetated　areas.　This　research　provides　a　basis　of　reference　for　the　reasonable　allocation　of　water　resources　and　restructuring　of　vegetation　patterns　in　salinized　areas.　©　2018　CAAS.　Publishing　services　by　Elsevier　B.V
