An evaluation of regional landscape ecological risk (LER) in Harbin, a key center city Northeast China, is crucial for the long-term sustainability its and economic development. This study aims to (1) assess spatiotemporal patterns LER Harbin from 2000 2020, (2) identify natural human driving factors influencing LER, (3) project future trends under multiple land use scenarios. To achieve these objectives, data 2000, 2010, 2020 were analyzed using pattern indices characterize patterns. GeoDetector was applied quantify spatial differentiation factor contributions LER. Furthermore, PLUS model employed simulate change three scenario settings. Moran’s I used evaluate autocorrelation. The results indicate following: Between cultivated woodland two most prevalent types with majority shifts occurring between groupings. main changes continuous increase development steady decrease unused area. overall has been trending downward over last 20 years, primarily falling within medium-risk range. Marked heterogeneity observed, displaying distribution “high west north, low east south”. riskiest regions concentrated around bodies water. 0.798, 0.828, 0.852, respectively, indicating significant local clustering mainly defined by “High–High” “Low–Low” agglomeration (4) Among factors, DEM exhibited greatest explanatory strength interaction annual precipitation recognized as dominant force disparities (5) projected scenarios 2030, priority showed slower rate land, suggesting that this an effective approach improving conditions. findings offer theoretical foundation scientific guidance management similar regions.
