紫色土坡耕地水量季节变异特征与平衡初步研究

open access: yesShuitu Baochi Xuebao, 2007
通过具有壤中流测定功能的紫色土坡地径流小区的定位观测,结合物质平衡方法研究紫色土坡耕地水量的季节变异特征与平衡问题。结果发现,坡耕地玉米生长期水量的主要支出项为农田蒸散量、壤中流,分别为278.07,187.32mm,农田蒸散率与壤中流径流系数分别为50.51%,34.03%,而地表径流系数、农田蓄水率模拟值分别为7.59%,7.94%;坡耕地生长期支出总量为229.08mm,总径流系数为41.61%;坡耕地生长期径流支出具有季节变异特征,地表径流是玉米播种-拔节初期径流的唯一支出方式,其径流系数为9 ...

全球变化下九龙江河流-河口系统营养盐循环过程、通量与效应 [PDF]

open access: yes, 2018
河流-河口系统是陆地与海洋物质循环的重要通道。人类活动和气候变化已显著改变营养盐循环并产生一系列生态环境效应(富营养化、有害藻华、缺氧、酸化等)。本文基于现场观测、实验模拟和模型分析结果,总结亚热带中小型河流——九龙江河流-河口系统的营养盐(氮、磷、硅)含量和通量的长期变化及主控因素、水体反硝化作用、梯级电站水库对营养盐的滞留、气候变化(暴雨事件、升温)影响营养盐输送与循环等方面的研究进展,讨论营养盐变化的潜在生态环境效应。与大型河流相比,中小型河流对人类活动与气候变化的干扰更为敏感 ...

Laws, Enforcement, and Strategy: A Multi‐Layered Qualitative Study of Multinational Enterprise Compliance Under European Union and Chinese Data Protection Regimes

open access: yesPolicy &Internet, Volume 18, Issue 2, June 2026.
ABSTRACT In an era of proliferating but divergent data protection regimes, the European Union's rights‐based approach and China's sovereignty‐centric model have become two dominant poles of global data governance. This article examines how multinational enterprises navigate compliance under these dual systems and how that compliance is shaped through ...

连续降雨作用下褐土坡面侵蚀及其水动力学特征

open access: yesShuitu Baochi Xuebao, 2020
为研究在长时间降雨侵蚀过程中北京褐土坡面侵蚀特征及其水动力学机制,通过室内人工模拟降雨试验,分别在60,90 mm/h雨强下对褐土坡面进行连续10场次降雨试验,探讨了坡面侵蚀过程中的产流产沙特征及其与水动力学参数间的关系。结果表明:(1)在雨强及次降雨量较一致的条件下,随降雨场次增加坡面次降雨产流量变动较小,而次降雨产沙量变化较大,60,90 mm/h雨强下次降雨产沙量的变异系数为23.94%和59.88%,且第10场降雨的产沙量仅为第1场降雨的59.74%和22.28%;(2)连续降雨条件下 ...
