Special Issue Information

Dear Colleagues,

Soil erosion is a major environmental problem globally, leading not only to land degradation and reduced land productivity but also effects on agricultural production and food security. Pollutants transported via runoff sediment have serious impacts on the ecology, environment, human survival and socio-economic development of downstream areas. Soil erosion can cause serious soil erosion problems, resulting in large amounts of soil nutrients flowing into rivers and lakes with surface runoff. Soil nutrient loss can cause a decline in land quality, reduce fertilizer utilization and pollute water bodies, causing ecological imbalance. Soil nutrient management not only presents a challenge to soil erosion research, but also acts as a basis for soil and water environment pollution investigation and assessment.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following: soil erosion and land degradation; soil nutrient loss and management; investigation and assessment of soil and water pollution; soil and water conservation, etc.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Through three stress path tests of unsaturated Ili undisturbed loess, the effect of soluble salt content on the deformation of net mean stress, suction, and deviated stress were investigated. The mechanical properties of the normalized compression curve, soil water characteristic curve and critical state line were revealed. The test results indicate that: in the isotropic compression test, the normal compression curves controlling different suctions can be characterized by using the initial void ratio and the yield net mean stress, and can be described as a two-parameter exponential function. In the triaxial shrinkage test, the soil water characteristic curves controlling vary net mean stresses are dimensionless by using saturated moisture and air entry value, and the normalization formula can be characterized by a single parameter exponential function. In the consolidation shear test, the corresponding effective net mean stress is calculated by suction and saturation. The critical state lines under the unsaturated condition controlling vary suctions can be described as the critical state line under the saturated condition on the plane of effective net mean stress and deviator stress. When the effective net mean stress is constant, the critical state lines under the unsaturated condition can be characterized by the degree of gas saturation and the ratio of unsaturated void ratio to saturated void ratio. The research will offer reference pointing at the regulation and utilization of water and salt in the loess region of Central Asia, so as to better guarantee the sustainable development of saline-alkali land project construction.

This paper mainly quantitatively analyzes papers in the field of soil erosion from an objective evaluation perspective. The purpose is to provide researchers in the field of soil and water conservation with a comprehensive understanding of the field. The bibliometric method was used to evaluate the technological innovation and evolution characteristics of soil erosion research. In terms of research scale, China and the United States have an absolute lead in this field. China started late, but the growth rate is faster. The evolution process of soil erosion research is classified into three stages (1991–2000, 2001–2010, and 2011–2020). In terms of innovation subjects (countries and institutions) in soil erosion fields, dominant countries exhibit more concentrated results, with an increase from 57% to 80% with respect to the ratio of the number of output papers in these countries to the total number of output papers in the research field of soil erosion. In contrast, research institutions are increasingly divergent, with a decrease from 36% to 26% with respect to the ratio of the number of output papers in the dominant institutions to the total number of output papers in the research field. The comparison results of the comprehensive innovation strength of major countries indicate that soil erosion research has experienced processes such as domination by the United States, and other countries have caught up via concerted efforts, with China and the USA finally leading comprehensively. The overall leading ability of China and the United States in soil erosion research continues to converge and improve. Belgium and other European countries have small research scale characteristics but greater influence capacities. The study of erosion mechanisms and erosion modelling has always been the main research direction in this field, while the quantitative study of soil erosion on large scales and its effects on element cycling comprises the current main research stream and development trend. The results of the present study could provide scientific support for a better understanding of the evolution of innovation characteristics in the field of soil erosion. Full article
