Existing studies generally focus on cropland or pasture, and thus there is a lack of comprehensive understanding of the landscape composition and configuration in complex agro-pastoral transitional zone. In this study, Ansai County in the ATNC was chosen as an experimental area. Four typical agroecosystem services (AESs), food provision (FP), soil carbon (SC), soil retention (SR) and water yield (WY) from 1980 to 2020, were simulated by spatially integrating a model of the agricultural system using the Environmental Policy Integrated Climate (EPIC) combined with geographic information systems technology. The impacts of different crop types, pasture configurations, and tillage practices on AESs under future climate scenarios were assessed in the context of agro-pastoral transition. Finally, the optimal landscape pattern configuration and management measures were identified through single-objective and multi-objective optimization models. The results showed that under historical scenarios, implementing policies such as converting cropland to pastureland improved SC and SR but reduced FP and WY. Compared to traditional and reduced tillage, no-till practices benefited the enlargement of AESs and the agricultural ecosystem. Notably, future climate change generally negatively affected AESs, especially under the Shared Socioeconomic Pathway (SSP5–8.5) climate scenario. The combination of planting corn and no-till measures would be ideal for optimizing the agricultural ecosystem in Ansai County. For the fragile ATNC, we should advocate conservation agriculture and policies converting cropland to pastureland to mitigate the adverse impacts of climate changes.

This study utilized 4515 publicly available soil samples to quantify the impacts of 19 extreme climatic indices (ECIs) on ΔSOC reservoirs in China through a hybrid space-for-time and meta-analysis approach. Overall, 16/19 ECIs were negatively correlated with ΔSOC, with the minimum temperature of the coldest night (TNn) showing the strongest negative correlation. Notably, topographic factors played a pivotal role in the modeling process, contributing an average of 25 %, followed by ECIs. Under the influence of the ECIs, SOC exhibited spatial variation. Extreme heat resulted in the greatest SOC losses in cold regions, such as North China, with average reductions of &gt; 5 %, whereas its impact was weaker in South China, with SOC losses of ∼3 %. Extreme cold and wet indices promoted SOC accumulation in the Northeast China, with increases of ∼3 %, but showed a weaker response in the humid region, where the SOC increased by only 1 %. At the national scale, the impacts of extreme climatic events on SOC in the 0–20 cm ranged from −2.36 Pg to 2.34 Pg. Different ecosystems responded variably, with forest and grassland ecosystems being more sensitive to ECIs, potentially due to higher organic matter inputs and greater ecosystem complexity. In contrast, bare land exhibited weaker responses due to limited vegetation cover and organic inputs.
