Exploring variations of ecosystem service value in Hangzhou Bay Wetland, Eastern China

•The ESV (ecosystem service value) of 1990, 2000 and 2010 at the Hangzhou Bay Wetland were aggregated from 8 ecological functions with remote sensing and GIS.•The temporal-spatial change of wetland ESV was analyzed for three decades.•This paper used coefficient of sensitivity to determine the dependence of ESV on the change of ecosystem value coefficient over time.•The total ESV first increased and then decreased, indicating that the ecosystem environment situation remains severe in Hangzhou Bay.
