New Phytologist, Volume 247, Issue 6, Page 2616-2629, September 2025.Summary Seagrasses are important contributors to environmental nutrient cycling in marine ecosystems and can improve water quality by absorbing excess nitrogen (N). However, these ecosystems are vulnerable to human‐mediated pressures, including marine heatwaves (MHWs), particularly those of longer duration. We performed an experiment simulating a 30‐d,

Shuitu Baochi Xuebao, 2000 在山西省隰县的小区试验表明，膨润土改性沥青乳剂覆盖地面后，可以快速产生草本植被，在暴雨来临前夕植被盖度较高。同时，对覆盖后的地面径流、土壤含水量、土层温度作了观测，初步认为，草本植被的产生是由于覆盖后增温作用、保水作用以及两者的优势协调产生的。

Shuitu Baochi Xuebao, 2017 为研究植被覆盖度对紫色土坡面侵蚀过程的影响，探讨有效控制水土流失的坡面植被临界盖度问题，利用人工模拟降雨试验与室内分析相结合的方法对紫色土坡面侵蚀过程进行分析。结果表明：（1）总体上，紫色土坡面产流量随植被覆盖度的增大而减小，二者之间呈现线性负相关，但是植被覆盖度在25%以下，径流量变化不明显，植被覆盖度达75%时，径流量处于较低的稳定值，明显低于植被覆盖度0%，25%，50%；（2）坡面侵蚀泥沙量随植被覆盖度的增加而减少，二者呈现二次项相关（R2=0.99），植被覆盖度25%以下对坡面减沙起到重要作用，

New Phytologist, Volume 247, Issue 3, Page 1117-1128, August 2025.Summary Environmental changes and their effects are among the most pressing topics of today's ecological research. Shrublands, although widespread across the globe, remain understudied in this respect. We conducted a global meta‐analysis of 81 shrubland sites subjected to experimental warming, shifts in precipitation (e.g.

Shuitu Baochi Xuebao, 2019 为探究雨强和植被覆盖度对花岗岩红壤坡面产流产沙的影响，通过室内人工模拟降雨试验，分析了不同雨强（0.5，1.0，1.5 mm/min）和植被覆盖度（0，20%，40%，60%）下坡面侵蚀的产流、产沙规律及相关关系。结果表明：（1）同一雨强下，初始产流时间随植被覆盖度增加而延迟，并随雨强增大而提前，雨强越大，产流时间提前越明显）（2）各坡面径流率、侵蚀率随植被覆盖度增加而减小，且植被覆盖度越高，径流率和侵蚀率波动范围越小，侵蚀过程越稳定）（3）有植被覆盖的坡面，产沙主要以0.25 ...
