Drain and irrigation facilitator effect on making sloping farm field of converted fields [PDF]

open access: yes, 2006
To promote the full-scale production of barley, soybean, crops for feed, or other farm produce in farm fields converted from paddy fields, an essential requirement is overcoming possible wet damage, drought damage or other impedimental factors to upland ...

Multiple global change factors alter the scaling of nitrogen to phosphorus in alpine plants

open access: yesFunctional Ecology, Volume 39, Issue 8, Page 2044-2055, August 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometry and allometry of nitrogen (N) and phosphorus (P) reflect nutrient absorption and dynamic allocation by plants, and can be regulated by global change factors (e.g. nitrogen enrichment, climate warming and altered precipitation). Yet, how multiple global

China's Eco‐Civilisation, Climate Leviathan, and Hobbesian Energy Transition

open access: yesAntipode, 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.

利用日、月及年降雨量估算年降雨沖蝕指數 [PDF]

open access: yes, 2014
The Universal Soil Loss Equation (USLE) is presently one of the most widely used models for evaluating soil erosion. The rainfall amount is often used to estimate the R factor for Universal Soil Loss Equation (USLE) modeling.

How Many Floods Have Occurred in China in the Past Decade? A Perspective From Social Media

open access: yesEarth'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.

Demographic and net primary productivity dynamics of primary and secondary tropical forests in Southwest China under a changing climate 气候变化背景下中国西南热带原始林和次生林的群落和净初级生产力动态研究

open access: yesIntegrative 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

Research on Bamboo Riparian Buffer Ecosystems for Diffuse Pollution Prevention [PDF]

open access: yes, 2010
进入农业系统的过量氮(N)、磷(P)极易通过地表径流或地下潜流、渗漏及农田排水进入水环境,引发水体富营养化。具有一定群落结构的河岸植被土壤系统内部具有较大的生物生存空间和相互作用区域,其间生物地球化学联合机制,可以减缓径流、捕获泥沙、截断或去除地表径流、壤中流或渗漏水及浅层地下水中的氮磷等元素,有效改善受纳水体的水质。了解河岸植被土壤系统削减污染物和净化水质的机制及其影响因素,有助于加强对河岸带的管理和重建工作,为防治面源污染提供科学依据。 本文采用土壤剖面渗透水分层采集装置 ...
