The Mechanism of Runoff on a Hillside Slope (1) Lysimeters and the Amount of their Surface Flow [PDF]

open access: yes, 1975
1. 山地小流域の水収支を考えてゆく過程での山腹斜面の役割を明らかにするため, 流域内の山腹にライシメーターを設置し, その流出量を測定した。ライシメーターは, 前報に用いたもので, 山腹斜面の三方を板で土壌層を分離し, 下方に開放した土壌断面から流出水を採取した。実験測定は1970年秋より開始し, 今回の報告については, 1972年5月から, 1974年8月までをデータとした。2.

Patriotic rabbits or toxic men? Media ideology, entextualization, and enregisterment on Chinese interfaces

open access: yesJournal of Linguistic Anthropology, Volume 35, Issue 2, August 2025.
Abstract This article argues that social actors' media ideologies about digital interfaces are key to the enregisterment of online activities. Focusing on an online register emergent from user activities around Year, Hare, Affair (YHA)—a state‐aligned Chinese animation—I explore how different metadiscourses evaluate this register by entextualizing ...

三峡库区水土流失综合治理优先小流域识别方法

open access: yesShuitu Baochi Xuebao, 2020
三峡库区水土流失严重,开展水土流失综合治理是减少入库泥沙和提高三峡工程综合效益的关键,而如何高效识别优先小流域,则是提高治理资金效益和科学决策的基础。以重庆市合川区为例,在区域土壤侵蚀评价的基础上,提出了水土流失面积法、土地利用-水土流失面积法和坡度-水土流失面积法3种优先小流域识别方法,并对其进行了比较分析。结果表明,坡度-水土流失面积法识别的优先小流域水土流失面积占比接近于水土流失面积法,同时又将坡度较大以及耕地、园地和采矿用地面积占比较大的小流域识别出来,纳入优先小流域中 ...

A social network analysis of an epistemic community studying neoliberal conservation

open access: yesConservation Biology, Volume 39, Issue 2, April 2025.
Abstract Researchers typically operate in epistemic communities: groups that share common approaches to research agendas and sociopolitical action and define areas of debate. Although productive in their own spheres, a lack of understanding among these communities can undermine scientific progress. Thus, analyzing epistemic communities is important for

Lessons for Transboundary Snow Leopard Conservation: Findings From a GPS Telemetry Study in Kangchenjunga Conservation Area, Nepal 跨境雪豹保护经验:来自尼泊尔Kangchenjunga保护区的GPS追踪研究结果

open access: yesIntegrative Conservation, Volume 4, Issue 1, Page 45-56, March 2025.
Understanding the spatial ecology and movement of snow leopards is crucial for their long‐term conservation. Our first GPS telemetry study in Nepal revealed that snow leopards of Nepal have much larger home ranges than previously thought and frequently cross international borders.

应用ARC/INFO预测芋子沟小流域土壤侵蚀量的研究

open access: yesShuitu Baochi Xuebao, 2001
依据实地调查资料及相关图形资料 ,建立了芋子沟小流域地理数据库。在地理信息系统 ARC/ INFO支持下 ,根据通用土壤流失方程式 ( USL E)对数据库实施运算操作 ,预测了芋子沟小流域土壤侵蚀量。结果表明 ,芋子沟小流域年平均输沙模数为 3 893 .3 8t/ km2 ,侵蚀强度属中度 ;占流域面积 2 9.4 8%的坡耕地产沙量占流域总产沙量的 81.98% ,占流域面积 69.5 2 %的其它地类对流域土壤侵蚀量的贡献率仅为 18.0 2 % ,坡耕地年均土壤侵蚀量为 10 82 6.5 4

小流域合理外引调水量分析

open access: yes水电水利, 2020
随着社会经济的不断发展,对部分地区而言在单一河道上修建水库,通过本流域来水量的径流调节已经无法满足水库供水任务要求。现必须从外流域引水、加大可调蓄水量方能保证新建水库的经济性合理性。考虑到新建水库的规模与外流域合理引调水量密切相关,故探讨如何分析外流域合理的可引调水量是必要的。
