Functional Ecology, Volume 40, Issue 4, Page 983-1000, April 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Organic phosphorus mineralization is a critical process in the phosphorus cycle, governing phosphorus bioavailability for plants. The PhoD gene, which encodes the key enzyme alkaline phosphatase, serves as a valuable biomarker for this process.

Integrative 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.

Shuitu Baochi Xuebao, 2000 针对石灰岩丘陵土层浅薄、干旱缺水的主要问题，在坡改梯的基础上，测定了不同旱作保水技术措施的土壤含水量、土壤物理性状、土壤水文状况、土壤养分含量、土壤水分特征曲线、土壤导水率和土壤有效水含量等综合指标。结果表明：其旱作保水效果为覆膜〉保水剂〉覆草〉松土〉对照；对寒露蜜桃产量和质量综合评价为覆膜〉覆草〉保水剂〉松土〉对照。

Abstract Plant phosphorus (P) acquisition strategy is considered to be an intrinsic driver behind plant succession. However, variations in plant P acquisition strategies in connection to soil P fraction changes after wetland drainage remain unclear.

Shuitu Baochi Xuebao, 2008 采用定位取样与烘干法,测定了榆林沙区几个树种土壤含水量。结果表明:各树种土壤含水量变化规律为:樟子松>柠条>紫穗槐>沙柳>沙蒿>花棒-踏郎;土壤含水量的垂直分布格局为表层土壤含水量最低,随着土壤深度的增加,土壤含水量呈增加趋势;土壤含水量的季节动态规律为不同树种土壤含水量具有明显的季节变化规律,土壤含水量按季节变化可分为3个阶段,4-5月的土壤水分弱失水阶段,6-8月的土壤水分消耗阶段,9-10月的土壤水分缓慢恢复阶段。

Shuitu 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 ...

不同土壤前期含水量对土壤分离临界水动力学特性及其抗剪强度的影响
Shuitu Baochi Xuebao, 2017 坡面土壤分离临界水动力参数的定量描述对完善土壤侵蚀物理模型具有重要意义。通过实测不同土壤前期含水量（5%～23%）和坡度（1°～10°）条件下黄壤坡面土壤分离临界水动力参数，并结合不同土壤含水量（3%～23%）对土壤抗剪强度的影响，综合分析及探讨不同土壤前期含水量、坡度和土壤抗剪强度与临界水动力特性的关系。结果表明：临界流量与不同土壤前期含水量和坡度呈幂函数减小关系，提出一种能够体现土壤前期含水量和坡度共同作用对临界水动力参数影响的预测方程。在坡度小于5°时，土壤前期含水量对临界水动力学参数影响较小 ...

Shuitu Baochi Xuebao, 2023 为探究不同前期土壤含水量条件下坡面产流产沙特征及产流产沙关系,以安塞黄绵土为研究对象,通过设置6个前期土壤含水量处理(5%,10%,15%,20%,25%,30%),采用室内人工模拟降雨试验来系统研究前期土壤含水量对坡面产流产沙过程的影响。每个含水量处理设置2个重复,坡面坡度为15°,设计雨强为90 mm/h,降雨历时为1 h。结果表明:(1)随着前期土壤含水量的升高,坡面初始产流时间幂函数减小,产流量线性增大。(2)坡面土壤流失量随前期土壤含水量增大呈幂函数增加,高含水量组(29.3 ...
