This study utilized the Remote Sensing Ecological Index(RSEI)to analyze the characteristics of ecological environ-ment quality(EEQ)evolution and its responses to environmental factors and land use changes in Fujian Province from 1990 to 2022.The results indicate:① From 1990 to 1995,EEQ in Fujian Province showed a"good in southeast,poor in northwest"spa-tial pattern;areas with inferior EEQ gradually increased from 2000 onwards,with improvement being noted after 2010.② EEQ transitions during 1990～1995,2005～2010,and 2010～2015 predominantly shifted from medium or higher levels to medium lev-els,while other years showed transitions from lower to medium or higher levels.EEQ in cultivated land areas mostly transitioned from lower to medium or higher levels.③ From 1990 to 2010,EEQ exhibited a trend of increasing in the northern part and de-creasing in the southern part,characterized by high volatility;from 2011 to 2022,it showed a trend of increasing inland and de-creasing along the coast,with lower volatility.④ Surface temperature rise and increased humidity positively influenced EEQ,while dryness had a negative impact in the south and a positive impact in the north.The vegetation index primarily negatively impacted EEQ.⑤ Except for forest and cultivated land,other types of land showed increasing trends,notably with significant growth in im-permeable surface area,impacting evolution patterns of overall land use.The declining trend of EEQ in Fujian Province suggests the need for targeted policy adjustments in ecological maintenance and governance.Future efforts should focus on standardizing land use structure and enhancing strategies for natural disaster protection to achieve balanced economic development and ecologi-cal prosperity.
