ABSTRACT Soil microbial communities provide numerous ecosystem functions, such as nutrient cycling, decomposition, and carbon storage. However, global change, including land‐use climate changes, affects soil activity. As extreme weather events (e.g., heatwaves) tend to increase in magnitude frequency, we investigated the effects of heat stress on activity respiration) that had experienced four different long‐term intensity treatments (ranging from extensive grassland intensive organic conventional croplands) two conditions (ambient vs. predicted future climate). We hypothesized both land use would reduce respiration (H1) experimental (H2). this be less pronounced soils with a history high‐intensity (H3), higher fungal‐to‐bacterial ratio show more moderate response warming (H4).

Abstract Land use/vegetation cover change, reflecting a range of human land use practices, is the most prevalent and immediate influence on alterations in soil quality. The physical structure crucial for safeguarding carbon (C) nitrogen (N), as it modulates protection mechanisms distribution these elements within soil. Nevertheless, impact C N accumulation under different same area remains unclear. This research collected samples from five types typical forest grassland transition zone Loess Plateau, including natural forests, artificial shrubs, meadows, farmland. We investigated topsoil structure, pools aggregates, driving factors types. Our results indicated that SOC macroaggregates shrublands, meadows was 16.4%, 23.7%, 8.6%, 40.7% higher than MBC 48.9%, 26.4%, 37.0%, 18.8% Soil storage aggregate stability were lowest farmland ( p < .05). changes markedly influenced by quantity contained large aggregates with size >0.25 mm. MBN closely related to enzymes. Environmental indirectly through impacting properties structure. These emphasized significance content. When formulating policies, we should fully consider effects after vegetation changes. It improve enhance maintain nutrients resist erosion.
