In the context of global warming and intensified human activities, quantitative assessment combined effects land use/cover change (LUCC) climate on hydrological cycle is crucial. This study was based simulation results future LUCC in Jinghe River Basin (JRB) using GFDL–ESM2M CA–Markov with SWAT models to simulate runoff changes under different scenarios. The revealed that annual precipitation average temperature JRB are increase, mainly reflected increase forest urban lands decrease farmlands. Changes dominated by precipitation, frequency extreme events increases concentration CO2 emissions. Under four scenarios, contribution −8.06%, −27.30%, −8.12%, +1.10%, respectively, whereas influence smaller, ranging from 1.14–1.64%. response risk increasing water-resources stress JRB, this can provide a scientific basis for ecological protection management development.

With global climate change and irrational human activities, regional water resource conflicts are becoming more pronounced. The availability of in watersheds can be indicated by the yield. Exploring factors that influence yield is crucial responding to protecting resource. Previous research on influencing has frequently adopted a macro-level perspective, which failed reflect mechanisms changes at local scale adequately. Therefore, this study proposes novel framework for integrally evaluating impacts activities services from both perspectives. Taking Ganzhou City, source Ganjiang River, as an example, results show following: (1) City had largest 1307.29 mm 2016, lowest was only 375.32 2011. spatial distribution pattern mainly affected surface environment, high-value regions area were predominantly located urban areas with flat terrain. (2) At scale, where contribute than 80% accounted 25% area. In comparison, impact 0.95%. contribution rate significantly greater change. (3) simulation four scenarios contributed (>98%) yield, higher (<2%). This puts forward pioneering views driving forces provides valuable theoretical basis protection ecological environment construction.

ABSTRACT In the face of escalating global warming and intensified human activities, it is crucial to quantitatively assess combined impacts future climate change (CC) land use (LUCC) on runoff. This study employed simulation results CC LUCC in Min-Tuo River Basin, utilizing CMIP6 CA-Markov models conjunction with SWAT model project runoff changes under various scenarios. The findings indicate an anticipated increase both precipitation average temperature future. Projected involves a reduction arable grassland, alongside expansion other cover types. Changes basin are predominantly influenced by precipitation, higher likelihood extreme events as CO2 emissions increase. Across four emission scenarios, impact varies from −5.21% +6.09%, while LUCC's contribution ranges +0.05% +0.07%. When factors considered, overall trend indicates decrease changes, ranging −0.27% +0.17%. These underscore greater influence compared LUCC, thereby providing scientific foundation for ecological conservation water resources management basin.
