Ecosystem services are the benefits delivering from the natural environment to human society. Ecosystem services are regarded as important tools for decision-makers to understand the impacts of land use and land cover (LULC) change. In this paper, the dynamic of four primary ecosystem service indicators (habitat quality, carbon storage, soil sediment, and water yield) were mapped and assessed over 1984-2014 based on InVEST model and their responses to LULC changes have been analyzed by the ecosystem service change index (ESCI) and ecosystem service state index (ESSI). The analysis was conducted on two scales: the entire city area (city scale) and the subset of land that was reclaimed (reclamation area). Our results confirmed the significant increment in land reclamation in Zhoushan City, within the context of rapid LULC change due to economic growth and population increase. Subsequently, over half of the reclamation area was used for human-induced urbanization and over a quarter for the fishery. For the whole territory, the most significant LULC conversions were observed between agricultural land and urban. The study period witnessed the degradation of habitat quality and soil sediment, an increment of the water yield and no significant change of carbon storage. Furthermore, most of the changes in LULC are significantly related to the dynamics of ecosystem services, which were more impacted in the reclamation area than the rest of the city. Our study highlights the importance of ecosystem service assessments for sustainable land planning and securing economic development.
