在全球气候变暖的背景下,土壤碳封存被《联合国气候变化框架公约》列为实现长期"碳中和"的关键途径之一。然而,土壤碳封存是一个涉及植物、微生物、岩石矿物等核心要素共同参与的复杂生物地球化学过程,其调控机理和提升途径尚不明确。基于此,本文通过梳理国内外研究进展,从植物输入、矿物保护、微生物转化以及岩石风化四个方面综述了土壤碳封存的关键过程与机制,总结了提升土壤碳封存的主要途径,并重点讨论和展望了生物地球化学研究方法和技术在探究土壤碳封存机制和提高土壤碳封存潜力方面发挥的作用,以期从生物地球化学视角深入理解土壤碳封存这一基于自然的气候变化解决方案,发挥地球科学基础研究的作用,助力实现国家"双碳"目标。

Land use influences soil biota community composition and diversity, then belowground ecosystem processes functions. To characterize the effect of land on biota, nematode communities in crop land, forest fallow were investigated six regions northern China. Generic richness, abundance biomass nematodes was lowest land. The richness diversity 28.8 15.1% higher than respectively. No significant differences indices found between but their network keystone genera different. Among genera, 50% omnivores-predators 36% bacterivores. proportion fungivores 20.8% lower complexity stability Soil pH, NH4+-N NO3--N major factors influencing while organic carbon moisture influenced by artificial management practices more dependent environment induced variation altered relationships trophic group proportions among genera.

Abstract Background Cereal/legume intercropping can enhance crop productivity and improve soil health in dryland farming. However, little is known about biological under maize/peanut intercropping. The aim of this study was to assess based on nematode communities a system. Methods We conducted field experiment with different planting patterns, including monoculture maize (M), peanut (P), intercropped (IM, maize; IP, peanut) determine the influence health. measured physicochemical properties communities, employed exploratory factor analysis combined cumulative normal distribution curve scoring identify potential traits. Results gave highest plant parasitic abundance, trophic diversity index, evenness structure index. enrichment index least Shannon channel identified four traits, basic nutrients biodiversity, food web complexity, slow energy channel, fast mainly represented by ammonium nitrogen structural omnivore-predator fungivorous abundance microbial biomass carbon bacterivorous respectively. systems improved comprehensive score health, especially soil. Intercropping significantly oil traits representing complexity compared corresponding soils. Conclusions Our results indicate that indicators reflect Among those improvement biodiversity were main reasons for improving through
