China is highly vulnerable to landslide disaster. Climate change alters the frequency and intensity of extreme rainfall events, and, together with land use change and infrastructure expansion, future landslide susceptibility is showing an increasing trend. To scientifically assess the potential risk of landslide disasters in China under multiple future scenarios, this study divides China into six geographic regions based on geomorphic characteristics and selects multi-source geo-environmental factors as well as climate and land use data under multiple SSP-RCP scenarios (SSP1-2.6, SSP2-4.5, and SSP5-8.5) from Phase 6 of the Coupled Model Intercomparison Project (CMIP6). The CatBoost algorithm is used to construct landslide susceptibility models for each region in four time periods: 2020, 2050 s, 2070 s, and 2090 s, and a multi-scenario simulation analysis is carried out. The results show that the area under curve (AUC) values of all CatBoost models exceed 87% and surpass 95% in most scenarios. Relative to 2020, both the mean and median landslide-susceptibility index increase in future periods. Under the high-emissions scenario (SSP5-8.5), most regions in China exhibit rising susceptibility, whereas under the low-emissions scenario (SSP1-2.6) the increase is comparatively moderate. These findings highlight changing dynamics across China, underscore the value of region-specific modeling, and provide key insights for future disaster-risk management and mitigation.

The southern East Kunlun Orogen (EKO) experienced protracted orogeny linked to the Proto-Tethys and Paleo-Tethys oceans. However, the evolution of the Proto-Tethys Ocean remains much less understood leaving the question of the timing of subduction initiation and magmatism. Here, we studied three early Paleozoic plutons exposed in the southern EKO: Kekesha (KKS) and Xialawen (XLW) gabbro-dioritic plutons and Longwakalu (LWKL) granitic pluton for geochronology, geochemistry and Sr-Nd-Hf isotopes. A KKS quartz diorite, XLW hornblende gabbro, and LWKL granite crystallized at 494, 470 and 477 Ma, respectively. The KKS gabbro-granodiorite series and XLW hornblende gabbros are enriched in light rare earth elements and large ion lithophile elements, but depleted in high strength field elements. The LWKL granites possess adakitic features: high Na2O content, Sr/Y and La/YbN ratios and differentiated heavy REEs. Isotopically, XLW hornblende gabbros and LWKL granites are less enriched isotopes (εNd(t) = −4.3 to −3.9; εHf(t) = −4.6 to +2.0) than KKS gabbro and granodiorite (εNd(t) = −7.0; εHf(t) = −7.2 to −4.8). Sr-Nd isotopic modeling suggests that KKS and XLW plutons were derived through partial melting of mantle wedge modified by different amounts of subducted terrigenous-dominated sediment derived melts. The LWKL adakitic granites were formed by high-pressure reworking of underplated arc-type intermediate rocks. The emplacement of early Paleozoic gabbro-granodiorite series and adakitic granites was related to subduction of the Proto-Tethys Ocean which started no later than ca. 500 Ma. Our new data along with available ages suggest that the supra-subduction magmatism of the Proto-Tethys Ocean in the southern EKO is episodic with peaks at ca. 495, 470, and 430 Ma. The first two episodes of magmatism mainly represent melting of enriched mantle wedge, and the third is the main pulse of magmatism formed by simultaneous melting of multiple sources of crustal rocks, subducted oceanic slab and mantle wedge.
