Shuitu Baochi Xuebao, 2022 以黄土丘陵区典型侵蚀沟道为对象,基于沟道剖面有机碳和137Cs数据,采用碳库重分布模型估算了典型沟道侵蚀诱发的CO2通量,并通过检验模型预测效率、解析影响因子,提出了模型校正的思路。结果表明:(1)在长期侵蚀作用下,沟道侵蚀区和沉积区均表现为剧烈的侵蚀效应,侵蚀区侵蚀速率介于30.99~46.44 mm/a,沉积区侵蚀速率介于34.20~37.88 mm/a,沉积区土壤流失速率略小于侵蚀区;(2)碳库重分布模型估算显示,侵蚀区与沉积区均表现为较强烈的碳源效应,侵蚀区CO2通量介于18.41~28.44 ...

New Phytologist, Volume 247, Issue 1, Page 144-159, July 2025.Summary Domesticated chickpea cultivars exhibit limited genetic diversity. This study evaluated the effects of chickpea domestication on phosphorus (P)‐use efficiency (PUE) under low‐P conditions, using a diverse Cicer collection, including wild species. Two wild Cicer species – 54 C. reticulatum accessions and 15 C. echinospermum accessions, and seven

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 为了阐释外源有机碳在土壤有机碳运转中的作用机制，以黑土为供试材料，进行了5年的室外培养试验，并结合室内全土及颗粒组分单独矿化培养试验，研究了不同外源有机碳对黑土有机碳（SOC）、颗粒有机碳（POC）含量及其矿化特征的影响。试验包括单施化肥、牛粪配施化肥、鸡粪配施化肥、秸秆配施化肥和树叶配施化肥5个处理。结果表明：（1）单施化肥黑土SOC的损失主要来源于POC的损失，外源有机碳有利于SOC和POC的累积，与对照相比，禽畜粪便处理的SOC和POC平均增加幅度分别为16.6%和27.8 ...
