“…The results show that (1) the SC_R and WY_R increased significantly during 2000–2020, exacerbating regional ecological degradation, while the CS_R, GP_R and HQ_R showed a decreasing trend. (2) The comprehensive risk was rising, with significant increases in the middle-high rolling hills in the southwest and the
Chengdu Plain in the east, which are mainly attributed to farmland reclamation and urban expansion. (3) Competition between different land uses exacerbated the trade-offs between GP_R and CS_R, SC_R, HQ_R, while showing spatial heterogeneity under the constraints of natural factors and topography. (4) A total of four ER clusters were identified, with the SC_R-GP_R-WY_R cluster dominating, and gradually transforming into the SC_R cluster as the landscape pattern changes. (5) Compared with socio-economic and natural factors, the proportion of forest land and cropland was the dominant factor influencing most ER changes. …”
