To　evaluate　the　spatiotemporal　changes　in　the　ecological　environment　of　eastern　Ukraine　since　the　Russia　-Ukraine　conflict,　this　study　used　MODIS　images　from　March　to　September　2020　and　2022　to　calculate　the　Remote　Sensing-Based　Ecological　Index.　In　2022,　compared　with　2020,　conflict　zones　exhibited　reduced　improvement　and　increased　slight　degradation,　whereas　nonconflict　areas　showed　marginal　enhancement.　Through　propensity　score　matching,　the　research　confirmed　the　causal　relationship　between　conflict　and　ecological　trends.　Pathway　analysis　revealed　that　the　conflict　contributed　to　0.016　units　increase　in　ecological　quality　while　reducing　the　improvement　rate　by　0.042　units.　This　study　provides　empirical　support　for　understanding　the　correlation　between　conflicts　and　specific　environmental　factors,　offering　technical　references　for　ecological　quality　assessments　in　other　conflict　areas　and　future　evaluations　by　the　Ukrainian　government.
