摘要

Investigating the spatial-temporal development of landscape ecological patterns via the “Production-Living-Ecological Spaces” perspective is crucial for improving land use planning, enhancing landscape connectivity, and improving environmental quality. The Yellow River Delta, which has a fragile ecosystem, can easily trigger landscape ecological risks. In light of the Land Use and Land Cover Change datasets covering the study area from 1980 to 2020, this study examined the evolutionary characteristics of landscape pattern changes by constructing a landscape ecological risk (LER) assessment system. Geographic detector models and geographically weighted regression were utilized to investigate the forces influencing the spatial heterogeneity of landscape ecological risk. The results indicate that (1) During the past 40 years, agricultural production land has remained the dominant landscape type. There has been an initial reduction in the ecological space area, followed by a gradual expansion. The area changes among different land types have gradually become more stable. (2) Based on the LER classification derived using the natural breaks method, the study area was largely characterized by very low and low risk. Most transitions occurred between adjacent levels. The dominant transition types involved shifts from low and medium to very low risk. (3) The LER was jointly influenced by multiple factors, among which digital elevation model and land use intensity constituted the dominant drivers. The interactive explanatory power was more intense than that of any individual factor. (4) In areas with intense human activities, land-use intensity and GDP make significant positive contributions to LER, thereby driving an increase in LER.
