摘  要：
作为“一带一路”倡议重点建设港口城市，烟台市的区位优势和发展状态尤为重要。对其生态环境时空特征变化的掌握有助于在应对该区域中全球变化所带来的影响中获得先机，同时为相似地区发展模式和生态规划提供理论指导。以谷歌地球引擎为主要载体，基于中分辨率光谱成像仪（MODIS）数据产品集，计算了烟台地区的遥感生态指数（RSEI），结合土地利用覆被变化（LUCC）、气象和人文数据分析了RSEI指数时空变化的驱动因子。研究结果显示：烟台地区的生态环境质量整体呈现稳中向好的状态，各用地类型之间未发生剧烈转换，人为活动未对该地区生态环境造成重大影响。

摘  要：
As a port city under the national strategic key construction of the "Belt and Road", Yantai's location advantages and development status are particularly important. The understanding of the changes in the spatial and temporal characteristics of the ecological environment can help to gain a head start in coping with the impact of global change in the region, while provide theoretical guidance for the development model and ecological planning of similar regions. In this study, using Google Earth Engine(GEE) as the main carrier, the RSEI of Yantai was calculated based on the data product set of MODIS. Then, the drivers of spatial and temporal change of the RSEI were analyzed by combining land use cover change(LUCC), meteorological data and human activities. The results showed that the overall quality of the ecological environment in Yantai is stable and improving, there is no drastic transformation between various land types, and human activities have not had a major impact on the ecological environment of the area.
