Shuitu Baochi Xuebao, 2021 为探究引起三峡库区农业小流域土壤侵蚀的主要次降雨因子，通过天然降雨观测资料，分析忠县石盘丘小流域2019年侵蚀性降雨年内分布特征和典型次降雨条件下A和B 2个集水区产沙过程的变化规律，采用相关性分析方法，揭示次降雨产沙的主要影响因素。结果表明：（1）全年119场降雨资料中，有19场为侵蚀性降雨。全年侵蚀性中雨共发生10次，是侵蚀性降雨中最常见的降雨类型。暴雨及以上降雨是造成研究区产沙量最大的降雨类型。（2）在典型中雨、大雨和暴雨产沙事件中，B集水区产沙量分别是A集水区的5.13，1.66，7.56倍 ...

China's Eco‐Civilisation, Climate Leviathan, and Hobbesian Energy Transition
Antipode, Volume 57, Issue 3, Page 830-861, May 2025.Abstract Scholars have hitherto tended to theorise China's ecological civilisation project either as a form of environmental authoritarianism or as a vision of eco‐socialism. This paper contributes to the conversation by conducting a textual analysis of Chinese scholarly discussions on eco‐civilisation.

Shuitu Baochi Xuebao, 2017 通过对降雨移动方向上不同雨强和降雨历时的研究，揭示移动降雨坡面产流产沙关系及其变化规律，采用2个降雨移动方向（沿径流向上和向下移动）、2个雨强（1.35，2.75 mm/min）和2个降雨历时（60，120 min）在室内进行模拟移动降雨试验，分析不同降雨移动方向、不同雨强和降雨历时坡面产流产沙特征。结果表明：（1）向上移动降雨，相同历时（相同雨强）条件下，大雨强（长降雨历时）初始产流时间为140 s（240 s），比小雨强（短降雨历时）提前165 s（65 s）。（2）向下移动降雨，雨强越大 ...

How Many Floods Have Occurred in China in the Past Decade? A Perspective From Social Media
Earth's Future, Volume 13, Issue 4, April 2025.Abstract Global climate change has led to frequent and widespread flood disasters in China. Traditional flood disaster investigations mainly focus on major flood events, and small‐scale flood events are often overlooked. This study utilized the Sina Weibo social media platform to detect flood events in 370 cities in China from 2012 to 2023.

Shuitu Baochi Xuebao, 2023 通过野外微小区原位观测试验,基于降雨过程中降雨的集中时段对2017—2021年34次侵蚀性降雨雨型进行划分,系统分析雨型变化对黄土坡面细沟间侵蚀的影响及坡度效应。结果表明:研究区以前期型降雨为主,占总场次的52%,中期型和后期型降雨各占24%。中期型降雨对总产流量的贡献(25.56%±3.83%)显著低于前期型(36.70%±2.07%)和后期型(37.74%±4.01%)(p中期型>前期型,后期型和中期型降雨显著高于前期型。而降雨的场均产沙量则表现为后期型>前期型>中期型,且后期型降雨显著高于中期型 ...

Integrative Conservation, Volume 3, Issue 3, Page 230-243, September 2024.Tropical secondary forest at early sucessional stage had higher diamter growth rate and mortality rate, however, these forests also are more risked to droughts and high temperatures. Rising temperatures and more frequent droughts may decrease the carbon sink capacity of tropical forest ecosystems. Abstract Tropical forests are major carbon sinks on the

Shuitu Baochi Xuebao, 2018 为了探究人工降雨模拟试验结果的相似性，通过文献数据和观测数据，分析了人工降雨模拟试验与天然降雨小区观测在径流、泥沙方面的差异及其原因，从数值和规律2方面深入讨论了室内模拟降雨试验结果的相似性问题。结果表明：（1）模拟降雨试验弱化了降雨因子对坡面径流和泥沙的影响，且雨强/雨量或降雨侵蚀力越小，模拟试验的相似性越差。（2）模拟降雨试验中产流和产沙随坡度的变化规律明显不同于天然降雨观测情况。（3）在坡面条件和降雨作用相同的情况下 ...
