[Objective]The Yellow River Delta, a typical ecological fragile area, faces prominent landscape ecological risk (LER) due to multiple factors. Systematic understanding of landscape risk is crucial for optimizing landscape patterns and effectively addressing ecological challenges.[Methods] Taking Dongying, a typical city of the Yellow River Delta as the study area to construct a assessment framework of ecosystem service value and the probability of landscape ecological damage in terms of “stress-vulnerability-resilience”. The ESDA and Geographic detector were used to explore the spatial heterogeneity and influencing factors of LER at the grid scale.[Results](1) The average value of LER in Dongying is 0.15, generally shows a spatial pattern of “high in the north and east, low in the middle and southwest”. The total value of ecosystem services is about 3 175.99 billion yuan (93% of GDP), indicate unsustainable economic growth, showing a pattern of gradual diminution form the north and eastern coast to the southwestern. The probability of ecological damage is 0.43, showing a pattern of “staggered distribution of high and low in the north and east, and overall low in the southwest part”.(2) It is found that the LER showed significant clustering in spatial distribution, with a global Moran’s I index of 0.747. In terms of agglomeration zoning, the HH risk agglomeration area accounts for 32.48% of the area of the risk zone, which is mainly distributed in the continuous distribution zone formed by the coastal zone in the north and east of Dongying.(3) The LER of Dongying is mainly dominated by factors of socio-economic foundation and environmental location conditions. In the citywide area, the determinant of coastline distance was 0.43, which was the primary factor dominating the urban LER. In contrast, in the urban area, the determinant of population density was 0.38, which was the decisive factor influencing the urban LER.[Conclusions] This study enriches the LER assessment method theoretically, and provides empirical support for ecological protection and risk management in the Yellow River Delta.
