    Research progress of soil anti-scourability from 1962 to 2022

    • 摘要: 土壤抗冲性作为评定土壤抗侵蚀能力的重要参数,对于揭示土壤侵蚀规律具有重要的现实意义。为归纳土壤抗冲性自提出以来的发展历程,该研究详细梳理了1962—2022年中国土壤抗冲性研究的相关成果,客观评价了各时期表征指标及测定方法的优缺,系统分析了土壤抗冲性的影响因素及机理;同时基于中国知网(CNKI)和Web of Science数据库,借助CiteSpace网络图谱可视化手段分析了作者之间和机构之间的合作关系以及关键词所体现的热点话题。结果表明:1)土壤抗冲性表征指标和测定方法多样化导致相关研究结果难以比较;2)植物根系、土壤理化性质和坡度等因素对土壤抗冲性的影响机理存在争议,尚需进一步验证;3)土壤抗冲性数学模型主要围绕黄土区植物根系的增强效应而建立,较少涉及其他指标因子。该研究不足很大程度上限制了土壤抗冲性的发展,并阻碍了与其他学科的交叉与融合。今后的土壤抗冲性研究须结合现代技术重点监测坡面和流域尺度径流冲刷与土壤抗冲的相互过程,揭示土壤结构体间抵抗径流破坏和推动下移的能力。以区域水土保持与生态环境的效应评价和预测为导向,落脚于土壤侵蚀防控和水土流失综合治理,为未来水土保持工作的发展提供重要的决策依据。

       

      Abstract: Soil anti-scourability is one of the most important parameters to evaluate the resistance to soil erosion in practice. This review aims to summarize the conception development of soil anti-scourability. A detailed overview was also provided for the relevant achievements in the soil anti-scourability research in China from 1962 to 2022. A systematical evaluation was performed on the pros and cons of characterization indicators and measurements in each period. An analysis was also made to clarify the influencing factors and mechanisms of soil anti-scourability. At the same time, the CiteSpace networks map was visualized to determine the cooperation relationship between authors and institutions, as well as the hot topics embodied by the keywords using the CNKI and Web of Science database. The results showed that the research on the soil anti-scourability sprouted in the 1970s, and then the heat continued to increase. The largest number of publications was reported in 2012-2017, accounting for 24.47% of the total number of publications. Furthermore, the number of publications accounted for 94.80% of the total number of publications over the past 30 years. Nevertheless, the number of publications accounted for 84.83% of the total since the 21st century. It infers that the research on soil anti-scourability rose in the 1990s, and the heat reached the highest in the early 21st century. The density of the author and institution network maps was 0.003, indicating the characteristics of 'large concentration and small dispersion. The density of the keyword network map was 0.006, among which the soil erosion, plant root, Loess Plateau, vegetation restoration, and shear strength were closely related to the keywords. The number of publications in the three stages of 1962-1982, 1983-2002, and 2003-2022 accounted for 0.89%, 19.71% and 79.40% of the total, respectively. Specifically, some keywords were drawn relatively high attention in the second stage, such as the Loess Plateau, soil erodibility, Robinia pseudoacacia forest, and litter. The hot topics with high attention in the third stage included soil and water conservation, hedgerow, soil erosion, and root system. The intensity of keyword emergence in the third stage was 1.04-2.86 times that in the second stage, indicating the generally improved research on the soil anti-scourability. More importantly, the research gaps and bottlenecks were also summarized in this field. It was difficult to compare the relevant research, due to the diversity characterization indicators and measurements on the soil anti-scourability. Consequently, it was suggested that the water requirement of 1 g of dried soil should be taken as the characterization index of soil anti-scourability. In the determination, the field water discharge scouring should be given priority, followed by the undisturbed soil scouring flume. There was a controversial influence mechanism of plant roots, soil physical and chemical properties, and slope on the soil anti-scourability. The mathematical model of soil anti-scourability was mainly built around the enhancement effect of plant roots in the loess area. It is still lacking in the interdisciplinary research on soil anti-scourability. The future study of soil anti-scourability should focus on the interaction between runoff erosion and soil anti-scourability at the slope and watershed scales. Modern technology can be used to reveal the resistance of soil structures to the runoff damage for better movement downward. The evaluation and prediction can also be made to clarify the influencing mechanism of the regional water and soil conservation, and ecological environment using the prevention and control of soil erosion, and the comprehensive treatment of water and soil loss. The finding can provide an important decision-making basis for the development of future water and soil conservation.
