Global　climate　fluctuations　pose　challenges　not　only　to　natural　environments　but　also　to　the　conservation　and　transmission　of　human　cultural　and　historical　heritage.　World　Heritage　Sites　are　pivotal　regions　for　studying　climate　change　impacts　and　devising　adaptation　strategies,　with　remote　sensing　technology　showcasing　significant　utility　in　monitoring　these　impacts,　especially　in　the　Mediterranean　region’s　diverse　and　sensitive　climate　context.　Although　existing　work　has　begun　to　explore　the　role　of　remote　sensing　in　monitoring　the　effects　of　climate　change,　detailed　analysis　of　the　spatial　distribution　and　temporal　trends　of　landscape　stability　remains　limited.　Leveraging　remote　sensing　data　and　its　derived　products,　this　study　assessed　climate　change　impacts　on　the　Causses　and　Cévennes　Heritage　Site,　a　typical　Mediterranean　heritage　landscape.　Specifically,　this　study　utilized　remote　sensing　data　to　analyze　the　trends　in　various　climatic　factors　from　1985　to　2020.　The　landscape　stability　model　was　developed　utilizing　land　cover　information　and　landscape　indicators　to　explore　the　landscape　stability　and　its　distribution　features　within　the　study　area.　Finally,　we　adopted　the　Geographical　Detector　to　quantify　the　extent　to　which　climatic　factors　influence　the　landscape　stability’s　spatial　distribution　across　different　periods.　The　results　demonstrated　that　(1)　the　climate　showed　a　warming　and　drying　pattern　during　the　study　period,　with　distinct　climate　characteristics　in　different　zones.　(2)　The　dominance　of　woodland　decreased　(area　proportion　dropped　from　76%　to　66.5%);　transitions　primarily　occurred　among　woodland,　cropland,　shrubland,　and　grasslands;　landscape　fragmentation　intensified;　and　development　towards　diversification　and　uniformity　was　observed.　(3)　Significant　spatiotemporal　differences　in　landscape　stability　within　the　heritage　site　were　noted,　with　an　overall　downward　trend.　(4)　Precipitation　had　a　high　contribution　rate　in　factor　detection,　with　the　interactive　enhancement　effects　between　temperature　and　precipitation　being　the　most　prominent.　The　present　study　delivers　a　thorough　examination　of　how　climate　change　affects　the　Causses　and　Cévennes　Heritage　Landscape,　reveals　its　vulnerabilities,　and　offers　crucial　information　for　sustainable　conservation　efforts.　Moreover,　the　results　offer　guidance　for　the　preservation　of　similar　Mediterranean　heritage　sites　and　contribute　to　the　advancement　and　deepening　of　global　heritage　conservation　initiatives.　©　2025　by　the　authors.
