Rapid urbanization is a global phenomenon that has altered many ecosystems and created ecological risks. Landscape risk (LER) reflects the extent to which are threatened by human activities environmental change. LER can be also employed effectively monitor assess quality. A large number of studies have been conducted explore in basin from perspective Land Use Cover (LUCC). Ecological issues such as land degradation seriously hindered sustainable development Yellow River Basin (YRB). Based on LUCC data YRB four periods 1990, 2000, 2010 2020, this study aims determine most suitable spatial analysis scale using coefficient variation semi-variogram, analyzes landscape pattern YRB. We found exhibits obvious dependence, effect effective at 90 km × km. Throughout period, exhibited increasing fragmentation, decrease degree aggregation an increase heterogeneity distribution. In terms LER, it better state levels shifted higher lower levels, proportion lowest constantly increasing. This improves precision investigations offers valuable insights for future basin.

Optimization of ecological security patterns (ESP) is an important way to implement land space restoration and maintain regional sustainable development. How comprehensively identify ESP while maintaining the balanced development each ecosystem service key issue in identification construction at present. Using data on use, meteorology, vegetation biomass socio-economic statistics, quality six typical services Shule River basin (SRB) 2010 2020 were calculated for food supply, water conservation, carbon fixation oxygen release, habitat quality, soil conservation culture leisure. The ordered weighted averaging (OWA) model was introduced priority areas as source, minimum cumulative resistance (MCR) used extract corridors nodes. Based ant colony algorithm optimal paths study area, spatial scope corridors, potential recovery points, construct optimization ESP. results show that temporal differences SRB significant, showing characteristics overall dispersion small concentration. 76 source patches with a total area 2.29 × 104 km2; 54 length 3161.87 km; 36 nodes identified. Overall, shows network complete but there still room optimization, local problems are prominent. extracted 4.21 km2, 4 points. Finally, "two two belts, three areas" determined.

Regional ecological security pattern (ESP) can provide the basis for regional territorial spatial planning and urban protection. Taking Wuhan metropolitan area as study area, a binary logistic regression model was used to quantify evolutionary driving forces transformation risk of land. An identification framework source based on "quality-risk-demand" constructed identify by calculating land comprehensive value from three aspects quality, degradation risk, human demand. The resistance surface calculated according land-use type nighttime light data, further using circuit theory range its key areas corridors, specific ESP their priority area. results showed sources were 382.4 km2, accounting 17.3% corridors in terrestrial ecosystem (TEC) 14.38 with an average width 77.8 m, including 4.99 km2 pinch points 3.71 barriers, indicating poor actual connectivity TEC.
