• Constructing a Novel Remote Sensing Ecological Index (NRSEI) suitable for assessing urban agglomerations. • Analyzing the Ecological Environment Quality (EEQ) of urban agglomerations from natural, social and economic perspectives. • The interaction of multiple factors accelerates the spatial differentiation of EEQ in urban agglomerations. In response to rapid urbanization, urban agglomerations have become pivotal spatial entities for fostering high-quality social and economic development, yet they face increasing ecological pressure. Balancing urban growth with ecological sustainability is a critical issue requiring immediate attention. This study utilizes the Google Earth Engine (GEE) platform, integrates MODIS imagery and NPP-VIIRS data to develop a Novel Remote Sensing Ecological Index (NRSEI). This index comprehensively characterizes key environmental factors, including greenness, heat, wetness, air quality, and human activity. The NRSEI is then used to assess the Ecological Environmental Quality (EEQ) of the Yangtze River Delta Urban Agglomeration (YRDUA) over the period from 2012 to 2021. Spatial correlation analysis is employed to investigate the dynamic evolution and spatial characteristics of EEQ in the region. Additionally, the Geodetector is applied to identify and evaluate the natural, social, and economic factors driving variations in EEQ across the urban agglomeration. Key findings reveal that: (1) Between 2012 and 2021, the YRDUA’s EEQ showed an upward trend,...
