Shuitu Baochi Xuebao, 2022 为探究在非灌溉季节施加生物炭对滴灌棉田耕层土壤水热特性和三相结构的调控效应。设置生物炭15(B1),30(B2),45(B3),60(B4),0(B0) t/hm25个施加量,分析其对新疆滴灌棉田非灌溉季节耕层土壤(0—40 cm)三相结构、总孔隙度、土壤温度和土壤含水率的影响。结果表明:与对照处理相比,施炭处理使土壤固相体积降低2.58%~10.74%,总孔隙度增加3.38%~12.05%;同时,施炭处理的融后土壤质量含水率较对照处理提高1.07%~2.65%;施炭处理的土壤导热系数降低 ...

Global Change Biology, Volume 31, Issue 11, November 2025.This study assessed the potential impacts of climate and land‐use change on soil fungal diversity across four North American biomes. We found that climate change typically caused both diversity losses and gains, particularly in coniferous forests and among arbuscular mycorrhizal fungi, whereas land‐use change mainly reduced diversity, especially in ...

Review of Policy Research, Volume 42, Issue 6, Page 1428-1449, November 2025.ABSTRACT In Colorado, cattle farming—the state's leading agricultural sector—is a significant source of methane emissions. In response, both the government and producers have initiated efforts to mitigate the effects of climate change and enhance sustainability.

Effects of crop species on soil functions and soil multifunctionality are species‐specific
Functional Ecology, Volume 39, Issue 9, Page 2354-2369, September 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Soil multifunctionality is essential for sustainable agriculture, as soils not only need to support crop growth but also maintain soil biodiversity and sustain other critical ecosystem functions.

Functional 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.

Functional 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.

Shuitu Baochi Xuebao, 2005 以夏津县黄泛沙地130 m×260 m的农田防护林网为研究对象,对林网内外的风速、空气温度、空气湿度、土壤温度、土壤湿度及水面蒸发进行了对比分析。分析结果表明:农田防护林具有改善小气候的功能,可以降低风速,增加空气湿度和土壤湿度,调节空气温度和土壤温度,减小水面蒸发,防风固沙,减少土壤风蚀量,林网内3 H~5 H处的防护效应最好。

Shuitu Baochi Xuebao, 2008 在海拔2 500,2 700,2 850,3 000 m的草原上利用Li-6400-09土壤呼吸叶室测定仪测定一个生长季节祁连山排露沟流域放牧草原土壤呼吸速率,分析不同环境条件下土壤CO2释放速率对气候和土地利用的反馈作用。辅助测定地面温度(0 cm、最低温度和最高温度)、地下温度(5,10,15,20 cm)、空气温度、土壤含水量。通过2003-2006年的观测结果表明:(1)土壤呼吸速率有明显日变化规律,7:00-14:00逐渐升高,14:00达到最大值,其值为8.92μmol/(m2.s ...

Shuitu Baochi Xuebao, 2022 为了解内蒙古河套灌区农田防护林内冻融期土壤水盐状况及运移规律, 在2020年10月至2021年4月实测土壤水分、盐分、温度及相关气象数据, 并进行相关分析。结果表明: 土体表层温度波动较大, 随土层深度加深土体温度变化逐渐平缓。冻结期气温下降速率低于消融期气温回升速率, 加之土壤温度变化的滞后性, 冻结期比消融期长10天左右。季节性冻融冻结作用导致表层土壤含水量升高、深层含水量降低, 消融解冻时期, 土壤含水量逐渐降低。两侧林带农田边缘(0.3 H、4 H)土壤表层含水量相比农田内部(1 H、2 H、3

Shuitu Baochi Xuebao, 2017 为研究煤矿区用矸石作为垫底基质进行土壤剖面重构土壤水分再分布过程和剖面热扩散与气体浓度变化特征，以指导工程设计和重构土壤熟化技术应用，在实验室设计了一种煤矿区重构土壤水气热运移模拟装置，通过布设在土柱系统不同深度的温湿度传感器和CO2浓度检测仪，连续监测重构土壤剖面含水量、温度和CO2浓度。结果表明：煤矸石层具有良好的阻水性，阻碍水分的入渗，增加上层土壤的持水能力。但是，煤矸石的持水性差，煤矸石层的含水量远低于土壤层10%左右；煤矸石具有更佳的热扩散性，在加热过程中煤矸石层的温度远大于土壤层 ...
