Escaping social–ecological traps through ecological restoration and socioeconomic development in China's Loess Plateau

open access: yesPeople and Nature, Volume 5, Issue 4, Page 1364-1379, August 2023., 2023
Abstract The social–ecological trap is an emerging concept that describes situations in which self‐reinforcing social and ecological feedbacks maintain or push a social–ecological system towards an undesirable state and threaten the sustainability of human societies.

Key n‐Gram Extractions and Analyses of Different Registers Based on Attention Network

open access: yesJournal of Applied Mathematics, Volume 2021, Issue 1, 2021., 2021
Key n -gram extraction can be seen as extracting n‐grams which can distinguish different registers. Keyword (as n = 1, 1‐gram is the keyword) extraction models are generally carried out from two aspects, the feature extraction and the model design.

Spatial composition and premise arrangement of traditional Manchu village in Northeast China

open access: yesJAPAN ARCHITECTURAL REVIEW, Volume 3, Issue 3, Page 346-358, July 2020., 2020
Spatial composition has changed massively even also in Shengli Village, a traditional Manchu village, because of the land and agricultural policies carried out by the government after the foundation of People's Republic of China. Especially according to the political compactification of residential area executed in the late 1960's, farmland behind the ...

Threats to biodiversity from cumulative human impacts in one of North America's last wildlife frontiers

open access: yesConservation Biology, Volume 32, Issue 3, Page 672-684, June 2018., 2018
Abstract Land‐use change is the largest proximate threat to biodiversity yet remains one of the most complex to manage. In British Columbia (BC), where large mammals roam extensive tracts of intact habitat, continued land‐use development is of global concern.

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.

Effects of Grass Cover on the Overland Soil Erosion Mechanism Under Simulated Rainfall

open access: yesWater Resources Research, Volume 61, Issue 2, February 2025.
Abstract Existing research on soil erosion primarily focuses on the individual effects of factors such as rainfall intensity, slope gradient, grass cover, and soil characteristics, with limited exploration of the interactions among these factors. This study investigated the mechanisms of soil erosion on overland covered with vegetation in the Loess ...

Effects of Vegetation Restoration Type on Soil Greenhouse Gas Emissions and Associated Microbial Regulation on the Loess Plateau

open access: yesEcology and Evolution, Volume 14, Issue 12, December 2024.
Greenhouse gas (GHG) emissions from soils play a significant role in contributing to global warming. Vegetation types especially affect soil GHG production. Our findings suggest that the restoration of natural grassland and artificial N‐fixing shrubland like Caragana korshinskii should be encouraged to alleviate GHG emissions, with the practical ...

萨拉乌苏河流域末次间冰阶气候 - 以米浪沟湾剖面为例 [PDF]

open access: yes, 2007
米浪沟湾剖面末次间冰阶层序粒度和化学元素波动韵律与由古流动砂丘砂和上覆河湖相或古土壤构成的沉积旋回颇为一致。古流动砂丘砂犹如现代流动砂丘砂, 是东亚冬季风主导下干冷气候的产物; 河湖相和古土壤颗粒细化, 化学、生物等地球风化程度增强, 含较多喜暖的软体动物化石, 指示其偏南夏季风主导下的温暖湿润气候。据此, 末次间冰阶萨拉乌苏河流域至少经历了10次温湿(W事件)和9次冷干(C事件)气候波动, 且可划分为MIS3e(58.85~48.98 ka BP)、MIS3d(48.98~39.55 ka BP ...

黄土高原地区土壤养分资源分区及其评价

open access: yesShuitu Baochi Xuebao, 1994
黄土高原地区土壤养分从黄土丘陵区、鄂尔多斯台地风沙区向内环辐射,由低增高;但是黄土高原地区氮磷缺乏,钾肥在一些地区和一些土壤上有显著增产效果,并能提高作物的品质。微量元素在一些土壤上也是缺乏的。今后在肥料上要进行二元或多元复合肥的施用。
