Shuitu Baochi Xuebao, 2019 通过田间小区磁化水滴灌试验，研究了磁化水膜下滴灌对土壤水盐分布特征、棉花生长特性及产量的影响。结果表明：磁化水灌溉可以提高土壤含水量，促进棉花根系对水分的吸收，0-100 cm土层内磁化强度为3 000 Gs时的土壤含水量最大，保水效果最好。磁化水灌溉可以有效降低土壤盐分含量，加快土壤盐分的淋洗，0-100 cm土层内各磁化水处理土壤平均含盐量表现为3 000 Gs < 4 000 Gs < 1 000 Gs < 5 000 Gs < 0 Gs，磁化淡水处理的土壤脱盐率为2.7%~28.2%，3 000

World Water Policy, Volume 9, Issue 3, Page 456-480, August 2023., 2023 Abstract Groundwater is a vital resource under threat in island communities. Karainagar, a 22 km2 island, is one of seven islands off the coast of Jaffna in Northern Sri Lanka, with its population of just about 11,000 persons, experiences seasonal water shortage, and salinity in groundwater as twin threats impacting on their lives.

An emerging coastal wetland management dilemma between mangrove expansion and shorebird conservation
Conservation Biology, Volume 36, Issue 5, October 2022., 2022 Abstract Coastal wetlands around the world have been degraded by human activities. Global declines in the extent of important coastal wetlands, including mangroves, salt marshes, and tidal flats, necessitate mitigation and restoration efforts. However, some well‐meaning management actions, particularly mangrove afforestation, can inadvertently cause ...

Representation of the world's biophysical conditions by the global protected area network
Conservation Biology, Volume 36, Issue 2, April 2022., 2022 Abstract Protected areas (PAs) are often implemented without consideration of already existing PAs, which is likely to cause an overrepresentation of certain biophysical conditions. We assessed the representativeness of the current PA network with regard to the world's biophysical conditions to highlight which conditions are underprotected and where ...

Jellyfish blooms restructure plankton dynamics and trophic linkages in coastal waters
Functional Ecology, Volume 40, Issue 5, Page 1443-1460, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Jellyfish blooms are increasing globally in frequency and intensity, introducing complex ecological interactions, yet the mechanisms by which they alter ecosystem structure remain poorly characterized due to a lack of sustained field observations.

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT The development of efficient and stable bifunctional electrocatalysts is a key challenge for the industrialization of hydrogen production by water electrolysis. In this work, Co‐doped NiS/Ni3S2 heterostructured nanowire arrays (Co–NiS/Ni3S2 NA) were successfully constructed by precisely modulating the phase‐selective behavior of nickel ...

Integrative Conservation, Volume 4, Issue 1, Page 85-94, March 2025.Chromolaena odorata and Ageratina adenophora are invasive species in Southern Yunnan, China; they have very differing, yet overlapping, climate niches. Both invaders produce a large number of small pappus‐bearing achenes every year. They grow in, and their seeds are dispersed to, both suitable and marginal habitats.

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, 2021 为了探究盐旱胁迫对土壤中氮素分布和棉花生长的影响，通过测坑试验研究滴灌区不同盐分、干旱条件下土壤全氮、硝氮、氨氮的分布和棉花生长情况。试验设置3种盐分梯度的土壤（电导率，EC）：3，6，9 dS/m，分别用T1、T2、T3表示；3个灌水量：2 700，3 600，4 500 m3/hm2，分别用W1、W2、W3表示（4 500 m3/hm2为当地推荐灌水量）。结果表明：当土壤盐分梯度> 3 dS/m时土壤全氮累积量显著高于低盐土壤（P<0.05），且土壤盐分对棉花花期生长影响较大 ...

Shuitu Baochi Xuebao, 2011 利用土柱模拟试验,设置淡水、咸水灌溉、咸水结冰和咸水结冰覆盖4个灌溉方式,研究咸水结冰灌溉条件下盐分运移及盐基离子Cl-、SO42-、HCO3-、Na+、Mg2+、K+和Ca2+的土层剖面迁移规律。结果表明:咸水直接浇灌使各土层土壤盐度提高,且盐分具有明显表层聚集特性,而咸水结冰后灌溉则显著降低表层0-40 cm土层的盐分盐度,配合秸秆覆盖措施则使表层的脱盐率进一步提高,特别是0-10 cm土层,土壤盐度仅为0.15 dS/m,与淡水处理尚未达显著性差异(P>0.05)。咸水结冰灌溉显著改变盐基离子Cl-
