Methods in Ecology and Evolution, Volume 11, Issue 1, Page 22-37, January 2020., 2020 Abstract Climate change is a world‐wide threat to biodiversity and ecosystem structure, functioning and services. To understand the underlying drivers and mechanisms, and to predict the consequences for nature and people, we urgently need better understanding of the direction and magnitude of climate change impacts across the soil–plant–atmosphere ...

Shuitu Baochi Xuebao, 2006 采用人工降雨和自然降雨的方法对紫色土坡地磷素迁移进行比较研究。研究结果表明：紫色土坡地产生地表径流和壤中流两种径流模式，壤中流其径流动态过程受降雨强度和表层作物覆盖度的影响；持续性变化的大雨强更容易引起土壤磷非点源输出，导致水体富营养化；在中到暴雨条件下，壤中流累积迁移流量低于地表径流，差幅决定于土壤表层界面（植被覆盖）特征，地表径流中的磷迁移量是壤中流迁移的3～4倍。

Shuitu Baochi Xuebao, 2021 横坡垄作是被广泛采用的保护性耕作措施之一。垄沟低洼处的积水可诱发壤中流，并可造成雨滴打击对土壤颗粒分离/搬运的增强与减弱作用并存。因此，横坡垄作坡面雨滴打击与壤中流交互作用对土壤侵蚀过程的影响有别于传统坡面。基于人工模拟降雨试验，对有/无雨滴打击作用（RI，WRI）自由入渗（FD）和壤中流（SP）2种试验处理下的产流、产沙过程进行了探究。结果表明：（1）径流量表现为SP+WRI > SP+RI > FD+RI > FD+WRI。雨滴打击作用和壤中流对径流的贡献分别为-47.09%~54.37%和41 ...

Functional Ecology, Volume 40, Issue 6, Page 1725-1739, June 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Root exudates play a key role as signals and nutrients in mediating plant–microbe communication. However, critical knowledge gaps remain regarding how root exudates mediate soil–microbe–plant interactions to regulate crop yield under long‐term straw mulching combined ...

World Water Policy, Volume 12, Issue 1, February 2026.ABSTRACT Water security in tropical regions faces escalating pressures from climate change, land‐use shifts, and population growth. We conducted a bibliometric review of 1146 peer‐reviewed articles (1964–2023) on tropical water security. Latent Dirichlet Allocation identified 13 thematic topics and their evolution. Publications rose sharply after 2012,

, 2007 为确定防治农田土壤侵蚀的标准,20世纪中叶美国土壤学家首先提出了“允许土壤流失量”的概念,之后这一概念又延伸应用到流域和区域土壤侵蚀评价。“允许土壤流失量”的概念在全球,包括在中国得到了广泛的应用。随着土壤侵蚀及相关学科的发展,特别是全球变化研究的深入,可持续发展及健康河流理念的提出及水土保持实践中遇到的新挑战,“允许土壤流失量”的科学性和实用性方面存在的缺陷逐渐显现出来。本文在简要介绍“允许土壤流失量&rdquo ...
