The study of Earth’s internal structure and dynamic processes is a fundamental scientific issue for understanding the evolution of the Earth system and the nature of geodynamic activities. This paper discusses the layered characteristics of Earth’s interior and the dominant dynamic processes, covering key research areas such as seismic tomography, gravity and magnetic field exploration, mantle convection, material cycling, and heat transfer. Seismic tomography reveals the detailed three-dimensional structure from the crust to the inner core, while gravity and geomagnetic observations provide critical constraints on the density distribution and conductivity structure of Earth’s deep interior, aiding in the identification of fluid dynamics in the mantle and outer core. Mantle convection is widely regarded as the primary driving force of plate tectonics and surface structural movements, and deep material cycling plays a crucial role in maintaining Earth’s long-term thermal state and chemical evolution. Research on internal heat transfer mechanisms helps to elucidate the distribution of deep heat sources and their control over global tectonic processes. With the continuous advancement of high-resolution geophysical imaging technologies, deep Earth experiments, geochemical tracing, and numerical simulation methods, studies on Earth’s internal structure and evolution are moving toward higher precision, multi-scale coupling, and interdisciplinary integration. In the future, the integration of seismology, geodynamics, geomagnetic and gravity exploration, and advanced simulation techniques is expected to deepen our understanding of internal Earth processes and provide theoretical support for planetary science, Earth system modeling, and resource and environmental research.

Soil organic carbon (SOC) is a core indicator for evaluating soil quality and health, playing a crucial role in the functionality and sustainability of agricultural ecosystems. Under the context of global climate change and intensive agricultural development, especially in arid and semi-arid regions, the accumulation and stability of SOC face significant challenges. This study focuses on the arid regions of northwest China as a typical case, systematically assessing the effects of different tillage practices (no-tillage vs. conventional tillage) and rotation systems (wheat/maize, wheat-winter rapeseed, and wheat) on SOC and its components. Field experiments were conducted to analyze the dynamic changes in key parameters such as soil respiration rate, organic carbon content, microbial biomass carbon, water-soluble organic carbon, and particulate organic carbon. The results demonstrated that no-tillage significantly reduced soil respiration rates while substantially increasing SOC accumulation in the surface soil layer (0–5 cm). Crop rotation systems exhibited distinct impacts on SOC, with the “wheat-winter rapeseed → maize” rotation showing the best performance in enhancing SOC accumulation. Furthermore, the combined management of no-tillage and optimized rotation significantly improved soil carbon storage characteristics. Particularly in arid environments, optimizing tillage and rotation systems effectively enhanced soil health and ecosystem stability. This study provides scientific evidence for sustainable agricultural development in northwest China, emphasizing the importance of optimizing tillage and rotation strategies to promote SOC accumulation, thereby achieving long-term stability and sustainability of agricultural ecosystems.

Drought stress is a key environmental factor limiting peanut production and nitrogen use efficiency. This study was conducted at an agricultural experimental station in Sichuan Province, employing the 15N tracer technique. Under normal water supply and mild drought stress conditions during the pegging and pod-setting stages, combined with different nitrogen fertilizer levels (0, 90, and 180 kg N/ha), the comprehensive effects of drought stress, and nitrogen fertilizer levels on peanut yield, nitrogen absorption and accumulation, distribution, and utilization efficiency were systematically analyzed. The results showed that drought stress significantly reduced peanut yield and nitrogen accumulation in plants, with the yield inhibition caused by drought during the pegging stage being significantly higher than during the pod-setting stage. In terms of nitrogen distribution, the nitrogen accumulated in kernels constituted the majority of the total nitrogen; however, drought stress significantly affected nitrogen distribution and transport efficiency among plant organs. Analysis of nitrogen fertilizer levels indicated that the medium nitrogen treatment (90 kg N/ha) under drought stress exhibited a higher nitrogen fertilizer recovery rate (38.8%) and lower nitrogen loss rate (12.6%), significantly improving nitrogen use efficiency. This study elucidates the regulatory mechanisms of drought stress on nitrogen utilization in peanuts, providing scientific insights for efficient peanut cultivation and fertilizer management in drought-prone regions.
