Abstract

Abstract With respect to the pedosphere, human activities in the last 100 years have been the major driver of soil change. Despite human activities being one of the main soil forming factors recognized by soil scientists (in addition to climate, organisms, parent material, relief, groundwater, and time), the Canadian System of Soil Classification (CSSC) emphasizes soil as a natural body. We argue human agricultural activities are direct and indirect drivers of significant changes to the carbon balance and cycling in A horizons of Gray Luvisolic soils in western Canada, resulting in changes to A horizon carbon stocks, structure, and micromorphology. Evidence from scientific literature, in-field soil profile observations, and the National Pedon Database are presented in support of our argument. We propose a polygenetic, two-stage model of Gray Luvisol soil formation. The first stage is dominated by the climate forcing of the Holocene, resulting in a relatively stable boreal forest ecosystem including perturbations from natural and human-induced wildfire and other disturbances. The second stage is dominated by direct, human-driven disturbances such as cultivation, release of exotic fauna (earthworms), and indirect human-driven disturbances associated with anthropogenic climate change. Further, we propose modest amendments to the CSSC to reflect a polygenetic model of soil genesis in Gray Luvisolic soils that preserve the balance between observation and interpretation inherent in the system.

灰色luvisol是多基因的
就土壤圈而言,人类活动在过去100年中一直是土壤变化的主要驱动力。尽管人类活动是土壤科学家公认的主要土壤形成因素之一(除了气候、生物、母质、地形、地下水和时间),但加拿大土壤分类系统(CSSC)强调土壤是一个自然体。作者认为,人类农业活动是加拿大西部灰色陆域土壤A层碳平衡和循环显著变化的直接和间接驱动因素,导致A层碳储量、结构和微观形态的变化。来自科学文献、实地土壤剖面观测和国家Pedon数据库的证据支持了我们的论点。我们提出了一个多成因的、两阶段的灰色土壤形成模型。第一阶段以全新世气候强迫为主,形成了一个相对稳定的北方森林生态系统,包括自然和人为野火等扰动。第二阶段主要是直接的、人为的干扰,如种植、释放外来动物(蚯蚓),以及与人为气候变化有关的间接人为干扰。此外,我们建议对CSSC进行适度修正,以反映灰色Luvisolic土壤中土壤发生的多遗传模型,以保持系统固有的观测和解释之间的平衡。

期刊介绍: The Canadian Journal of Soil Science is an international peer-reviewed journal published in cooperation with the Canadian Society of Soil Science. The journal publishes original research on the use, management, structure and development of soils and draws from the disciplines of soil science, agrometeorology, ecology, agricultural engineering, environmental science, hydrology, forestry, geology, geography and climatology. Research is published in a number of topic sections including: agrometeorology; ecology, biological processes and plant interactions; composition and chemical processes; physical processes and interfaces; genesis, landscape processes and relationships; contamination and environmental stewardship; and management for agricultural, forestry and urban uses.
