Introduction: 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. Outcomes: The dynamic of four primary ecosystem service indicators were 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). Our results confirmed the significant increment in land reclamation in Zhoushan City and 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. Discussion and Conclusion: Most 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.

生态系统服务动态响应沿海岛屿城市的大规模填海

简介:生态系统服务是自然环境为人类社会带来的收益。生态系统服务被认为是决策者了解土地利用和土地覆被变化的重要工具。结果:在1984-2014年期间,基于InVEST模型评估了四个主要生态系统服务指标的动态,并通过生态系统服务变化指数(ESCI)和生态系统服务状态指数(ESSI)分析了它们对LULC变化的响应。我们的结果证实了舟山市土地复垦的显着增加,超过一半的土地复垦面积用于人为引发的城市化,而超过四分之一的土地用于渔业。在整个领土上,农用土地和城市土地之间的土地利用变化和土地利用变化最为显着。研究期目睹了生境质量和土壤沉积物的退化,水产量的增加以及碳储量没有明显变化。讨论和结论:LULC的大多数变化与生态系统服务的动态显着相关,在填海区比整个城市受到的影响更大。我们的研究强调了生态系统服务评估对于可持续土地规划和确保经济发展的重要性。
