金沙江干热河谷典型区土壤退化机理研究——土壤侵蚀对土壤退化的作用

Shuitu Baochi Xuebao, 2002
云南省金沙江干热河谷典型区土壤侵蚀普遍而严重 ,对土壤退化有关键性影响。通过对该区不同退化土壤的侵蚀状况 ,从土壤侵蚀对土壤退化的空间分布格局 ,土壤侵蚀对土壤退化类型的发生和作用机制 ,探讨了土壤侵蚀对土壤退化的作用和影响。结果表明 :(1)侵蚀和水土流失是造成土壤退化的要因 ,不同侵蚀类型及其强度控制了土壤退化的空间分布 ;(2 )土壤侵蚀对土壤退化的作用机制主要是 :不同土壤侵蚀强度 ,决定了土壤退化发生类型的数量和程度 ;通过对该区几类主要土壤退化类型发生机制进行分析 ,看出土壤侵蚀是以冲刷剥蚀、

Ecohydrological characteristics of biocrusts explain divergent responses of biocrusts and grasses to rainfall reduction

Functional Ecology, Volume 40, Issue 9, Page 2843-2860, September 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Drylands are mainly structured by both vascular plants and biological soil crusts (biocrusts), the latter often regarded as a self‐organizing component of these ecosystems.

Farm‐Scale Recharge Pits for Improving Local Groundwater Availability: Insights From a Hardrock Watershed in Rajasthan, India

World Water Policy, Volume 12, Issue 3, August 2026.
ABSTRACT Groundwater depletion is a major challenge in semiarid, hard‐rock regions where irrigation demands often exceed natural recharge. This study evaluates the effectiveness of farm‐scale recharge pits as a local, supplementary, and community‐managed groundwater recharge solution in the Dharta catchment of Rajasthan, India. Alongside check dams and

Organ‐specific ozone and nitrogen legacies strengthen substrate control over litter decomposition

Functional Ecology, Volume 40, Issue 8, Page 2548-2559, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Elevated tropospheric ozone (O3) and nitrogen (N) deposition are concurrent atmospheric changes that strongly influence terrestrial carbon cycling, yet their combined effects on below‐ground decomposition remain poorly understood.

Conservative roots confer a larger microbial carbon pump efficacy than acquisitive roots by regulating microbial life‐history strategy

Functional Ecology, Volume 40, Issue 8, Page 2617-2627, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Root activity creates unique microbial hotspots in the rhizosphere by influencing the metabolic activities of surrounding soil microorganisms, profoundly regulating the dynamics of soil organic carbon (SOC). However, how root economic strategies affect the formation and

Alleviation of phosphorus rather than nitrogen limitation driven by permafrost and landscape effects on Dahurian larch forests

Functional Ecology, Volume 40, Issue 8, Page 2590-2601, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Permafrost thaw is reshaping nutrient dynamics in boreal forests, but its impacts on tree nutrient limitation and functional strategies remain poorly understood. Clarifying these responses is crucial for predicting the response of boreal forests to climate change.

Pinus armandii ectomycorrhizas mobilize aluminium‐bound phosphorus via carboxylates along a subtropical altitudinal gradient

Journal of Ecology, Volume 114, Issue 8, August 2026.
Ectomycorrhizal roots of Pinus armandii release more carboxylates than non‐mycorrhizal root segments, mobilizing Al‐bound inorganic P. Under the lowest available P conditions, they also secrete more phosphatase, promoting the mineralization of Al‐bound organic P.

丹江口库区石渣土土壤水分有效性研究

Shuitu Baochi Xuebao, 2002
土壤水分有效性的高低是制约石渣土生产能力的关键因素之一。对丹江口库区郧县石渣土 3种不同土石比土壤水分有效性的研究表明 :土壤水分有效性与土壤中的土 (2 mm)比关系密切。土壤蒸发、持水、导水和供水能力均与土壤中的土石比的大小有关。 3种土壤的持水能力 ,以石砾含量较少、质地较粘的土壤最强 ,以石砾含量较多、质地为壤质的土壤最低。而土壤水分蒸发能力与砾石含量呈负相关 ,土壤水分扩散率则与砾石含量呈正相关。适中土石比的土壤可提高入渗性能 ,减少蒸发量 ,提高供水性能。

水土保持森土壤肥力及其评价指标

Shuitu Baochi Xuebao, 2000
水土保持林作为保持水土、防止土壤侵蚀的特有林种，对于提高土壤肥力具有重要作用。常见的评价土壤肥力的指标有土壤酶活性、土壤有机质含量、土壤有机－无机复合体和微团聚体、土壤颗粒组成、土壤微生物数量以及土壤的其它理化性状等。通过分析不同水土保持林的土壤酶活性和土壤有机质含量。对其土壤肥力进行了评价。结果表明，有林地土壤肥力高于无林地；油松－阔叶树混交林土壤肥力比油松纯林更高；同一林分随着林龄的增长 ...
