季节性干旱区紫色土坡耕地土壤水分对降雨的响应

open access: yesShuitu Baochi Xuebao, 2020
以金沙江下游季节性干旱区紫色土坡耕地为研究对象,使用PR2/6土壤剖面水分测定仪和翻斗式雨量计对雨季0—100 cm土层的土壤含水量和降雨量进行连续观测,分析雨季紫色土土壤水分对降雨的响应。结果表明:每月平均土壤含水量之间存在显著差异,0—20 cm土壤含水率表现为9月 > 8月≈7月 > 6月,在整个雨季呈累加上升趋势。降雨量大小是影响土壤水分补给深度的决定因素。小雨(6.4 mm)只对10 cm土层土壤水分产生影响,平均提高12.35%;中雨(23 mm)对30 cm以上土层土壤水分产生影响,10 ...

Plant functional trait dissimilarity drives plant mixture effects on fine root biomass and trait variations

open access: yesNew Phytologist, Volume 249, Issue 2, Page 764-776, January 2026.
Summary Fine roots are critical for soil resource uptake, yet how declining plant diversity alters fine root biomass (RB) and traits remains unclear. We tested how plant functional trait dissimilarity in shade tolerance, drought tolerance, growth rate, and nitrogen‐fixation ability drives variation in root attributes.

陕北黄土区浅沟土壤水分空间分布特征

open access: yesShuitu Baochi Xuebao, 2019
以陕北黄土区吴起县合沟流域浅沟土壤水分为研究对象,通过对研究区不同深度、不同坡向、不同坡位的浅沟土壤水分空间分布特征进行研究。结果表明:(1)根据浅沟与原状坡油松生长量关系,将浅沟划分为深浅沟(40 cm ≤浅沟深度)和浅浅沟(20 cm ≤浅沟深度 上坡位 > 中坡位;深浅沟则为上坡位 > 下坡位 > 中坡位;在浅沟内,阴坡在中、下坡位土壤水分显著高于阳坡,阳坡上坡位土壤水分则高于阴坡;原状坡阴坡土壤水分显著高于阳坡。

Effect of primate protection on threatened and endemic vertebrates, plants, ecosystem services, and future climate refugia

open access: yesConservation Biology, Volume 39, Issue 5, October 2025.
Abstract Primates, 69% of which are threatened with extinction, are the third most specious order of mammals. We used primates as model taxa to examine the umbrella effects of primates on ecosystem services and the protection of other vertebrates and seed plants in Yunnan Province, China.

Ecological Restoration of Rubber Monocultures: Strategies for Biodiversity and Ecosystem Recovery in Tropical Regions 题目:如何将橡胶林恢复为多样森林?

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 345-353, September 2025.
Restoration of monoculture in protected and marginal areas can be organized into two phases (1) identification and prioritization of restoration sites based on remote sensing or field survey then assessing degradation level, and (2) implementation of appropriate restoration interventions.

天山北坡土壤水分时空变化及驱动力分析

open access: yesShuitu Baochi Xuebao
目的分析天山北坡土壤水分的时空变化特征及其影响因素,探讨耕地扩张对土壤水分的影响。方法基于2000—2020年的1 km日尺度土壤水分数据、土地利用数据、气象数据等数据,采用Theil-Sen Median趋势分析、Mann-Kendall显著性检验和Pearson相关系数分析,研究0~50 cm土层的土壤水分变化,并通过地理探测器模型探讨影响土壤水分的主要因素及其空间分异特征。结果2000—2020年,天山北坡0~50 cm土层土壤水分总体呈减少趋势,尤其在0~10 cm土层变化最显著 ...

Reoccurrence of Dust Storms in South Asia and Their Implications for Vegetation Health 南亚沙尘暴的再次出现及其对植被健康的影响

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 362-380, September 2025.
Occurrences of dust storms and long‐distance movement of dust across landscapes is constantly increasing in south Asia. This dust is expected to have profound impact on vegetation health and sustainability as dust may contribute to nutrient budgets of the forest ecosystems, while it could impart various stresses to the plants.

Tree mycorrhizal associations regulate relationships between plant and microbial communities and soil organic carbon stocks at local scales in a temperate forest

open access: yesFunctional Ecology, Volume 39, Issue 6, Page 1550-1566, June 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Forests store substantial amounts of soil organic carbon (SOC), but SOC stocks differ strongly between forest ecosystems dominated by arbuscular mycorrhizal (AM) or ectomycorrhizal (EcM) fungi.

Why are some invasive plant species so successful in nutrient‐impoverished habitats in south‐western Australia: A perspective based on their phosphorus‐acquisition strategies

open access: yesFunctional Ecology, Volume 39, Issue 2, Page 635-652, February 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Invasive plants are a major cause of the global biodiversity crisis; it is therefore crucial to understand mechanisms that contribute to their success. South‐western Australia is a global biodiversity hotspot with extremely low soil phosphorus (P) concentrations.

Ensuring sustainable water security through sustainable land management: Research evidences for policy

open access: yesWorld Water Policy, Volume 10, Issue 4, Page 1170-1186, November 2024.
Abstract Sustainable land management (SLM) practices is a key to reducing rates of land degradation and has proven to ensure water security by increasing soil moisture availability, decreasing surface runoff, decreasing soil erosion, increasing infiltration, and decreasing flood discharge. Land degradation is adversely affecting over 75% of the Earth's
