[Objective] The aim of this study is to clarify the temporal and spatial status of ecological environment quality and the main driving factors of its evolution under the continuous promotion of urbanization in Shandong Province, which is of great importance for recognizing the status quo of ecological environment in Shandong Province and formulating reliable protection strategies and systems in the later stage. [Methods] Based on remote sensing ecological index: a comprehensive index from 1991 to 2021, with the help of Sen trend method, coefficient of variation method, Hurst index method and geographical detector, the characteristics and driving factors of ecological environment quality change in Shandong Province were explored. [Results](1)From 1991 to 2000, the ecological environment quality in Shandong Province showed the decreasing trend and the change was relatively stable. From 2001 to 2010, RSEI showed the increasing trend, mainly stable change trend. From 2011 to 2021, RSEI changes in most areas showed the stable state, and RSEI in woodland and cultivated land areas showed the increasing trend, while other land use types showed the decreasing trend.(2)RSEI will mainly increase in the future period, and the change trend of different land use types in the future period is opposite to that in the past 31 years.(3)Land use change had the greatest impact on the spatial distribution of RSEI in Shandong Province during 1990—2000 and 2001—2010, and the spatial distribution of RSEI during 2011—2021 was greatly affected by humidity change and land use change, and the interaction between land use and other factors had a greater impact on RSEI. [Conclusion] There are significant differences in the sensitivity of ecological environment quality to environmental factors at different periods in Shandong Province, which is caused by the differences in the intensity and mode of human activities in different regions and the vulnerability of ecological environment in different regions. The visual expression of ecological environment quality can reflect the temporal and spatial evolution characteristics of ecological environment quality, and provide important reference information for the decision making of maintaining human-ecological environment balance.
