摘要

土壤盐碱化是指水溶性盐分在土壤剖面上部的积累。土壤盐分含量过高会影响作物产量、土壤健康和生态系统功能。这一现象威胁着农业、粮食安全、土壤稳定性和肥力,导致土地退化和丧失维持生命的基本土壤生态系统服务。在这篇综述中,我们综合了从全球到核心、孔隙和分子等不同时空尺度的土壤盐碱化研究最新进展,提出了新的见解,并介绍了我们对未来潜在研究方向的看法,以应对与土壤盐碱化相关的关键挑战和未决问题。在全球范围内,我们发现了在了解土壤盐碱化方面存在的重大挑战,即:(a)在估算受盐碱影响土壤的总面积方面存在相当大的不确定性;(b)基于地面的土壤盐碱化测量存在地理偏差;以及(c)缺乏有关干旱地区和湿地次生盐碱化过程的详细信息和数据,特别是有关对气候变化的响应的信息和数据。在核心尺度上,盐沉淀与不断变化的多孔结构对多孔介质蒸发通量的影响尚不完全清楚。这些知识对于准确预测土壤水分蒸发损失至关重要。此外,多孔介质的传输特性(如混合润湿条件)对盐水蒸发和由此产生的盐沉淀模式的影响仍不清楚。此外,还必须建立有效的连续方程,以准确表示实验数据和孔隙尺度数值模拟。

Multi-Scale Soil Salinization Dynamics From Global to Pore Scale: A Review

Multi-Scale Soil Salinization Dynamics From Global to Pore Scale: A Review

Soil salinization refers to the accumulation of water-soluble salts in the upper part of the soil profile. Excessive levels of soil salinity affects crop production, soil health, and ecosystem functioning. This phenomenon threatens agriculture, food security, soil stability, and fertility leading to land degradation and loss of essential soil ecosystem services that are fundamental to sustaining life. In this review, we synthesize recent advances in soil salinization at various spatial and temporal scales, ranging from global to core, pore, and molecular scales, offering new insights and presenting our perspective on potential future research directions to address key challenges and open questions related to soil salinization. Globally, we identify significant challenges in understanding soil salinity, which are (a) the considerable uncertainty in estimating the total area of salt-affected soils, (b) geographical bias in ground-based measurements of soil salinity, and (c) lack of information and data detailing secondary salinization processes, both in dry- and wetlands, particularly concerning responses to climate change. At the core scale, the impact of salt precipitation with evolving porous structure on the evaporative fluxes from porous media is not fully understood. This knowledge is crucial for accurately predicting soil water loss due to evaporation. Additionally, the effects of transport properties of porous media, such as mixed wettability conditions, on the saline water evaporation and the resulting salt precipitation patterns remain unclear. Furthermore, effective continuum equations must be developed to accurately represent experimental data and pore-scale numerical simulations.
