生态恢复工程作为应对全球气候变化和土地利用/土地覆盖变化的重要手段，对生态系统的碳汇功能和生态环境质量具有重要影响。然而，在黄河三角洲地区开展的各种ERPs对中国的生态安全战略具有重要意义。因此，本研究以土地利用数据和遥感影像数据为基础，借助ArcGIS和Google Earth Engine（GEE）平台，采用生态系统服务综合评价与权衡（InVEST）模型，采用改进的遥感生态指数模型等方法，深入研究了生态系统的演变趋势，对黄河三角洲地区实施ERP过程中的环境质量和碳储量进行了分析，并选取了实施ERP的重点区域进行深入分析，以确定ERP的实施效果。研究结果表明，从2001年到2020年，研究区的RSEI和碳储量水平具有相反的演变趋势。其中，RSEI呈波动上升趋势（0.4461（2001）和0.5185（2020）），而总碳储量呈波动下降趋势（30.67 Tg（2001）和26.40 Tg（2020））。但2015年至2020年，RSEI和碳储量处于相对稳定的水平，间接表明2015年至2020年期间开展的ERP取得了较好的综合实施效果。此外，2015 - 2020年改善效果较好的区域主要位于黄河三角洲口（C区和D区），其RSEI和总碳储量均呈现一定的上升趋势。该研究可促进黄河三角洲区域生态资源规划管理战略的制定，对黄河流域生态环境保护和高质量发展具有重要意义。
As an important means to address global climate change and land-use/land-cover (LULC) change, ecological restoration projects (ERPs) have a large effect on carbon storage functions and eco-environmental quality. However, the various ERPs carried out in the Yellow River Delta region have important implications for ecological security strategies in China. Therefore, based on land-use data and remote sensing image data, with the help of ArcGIS and Google Earth Engine (GEE) platforms, this study uses the Integrated Valuation of Ecosystem Services and Trade-offs (InVEST) model, an improved remote sensing ecological index (RSEI) model and other methods to deeply examine the evolutionary trends of eco-environmental quality and carbon storage during the implementation of ERPs in the Yellow River Delta and selects key implementation areas for in-depth analysis to determine the implementation effects of ERPs. Our findings suggested that the RSEI and carbon storage levels in the study area had opposite evolutionary trends from 2001 to 2020. Among them, the RSEI showed a fluctuating upwards trend (0.4461 (2001) and 0.5185 (2020)), while the total carbon stock showed a fluctuating downwards trend (30.67 Tg (2001) and 26.40 Tg (2020)). However, from 2015 to 2020, the RSEI and carbon storage were at a relatively stable level, which indirectly indicated that the ERPs carried out during the period from 2015 to 2020 had achieved a good comprehensive implementation effect. In addition, the areas with better improvement effects from 2015 to 2020 were primarily located in the mouth of the Yellow River Delta (Areas C and D), and their RSEI and the total carbon stock showed a certain upwards trend. This research can promote the formulation of the management strategy of ERPs in the Yellow River Delta, which is of tremendous importance to the ecological environmental preservation and high-quality development of the Yellow River Basin.
