Shuitu Baochi Xuebao, 2023 作为水土流失重点预防保护区,大别山南麓裸地坡面水土流失严重,为探究该区典型裸地坡面径流泥沙对降雨的响应,利用自动化径流泥沙监测设备对裸地径流小区的降雨—径流-泥沙过程进行监测。以2020年全年侵蚀性降雨数据为基础,依据降雨峰值时序划分雨型,分析了4种雨型的累计产流产沙特征和次降雨的径流泥沙特征,并建立了累计产流产沙的最优函数模型。结果表明:(1)大别山南麓降雨事件的I30是影响降雨事件的泥沙量和径流系数的重要因素;前期集中型和中期集中型降雨事件的泥沙量与前48 h内的降雨量呈显著正相关。(2 ...

Shuitu Baochi Xuebao, 2022 为明确喀斯特槽谷区岩石与坡面夹角对坡面产流产沙过程的影响,在6个岩石与坡面夹角(30°,60°,90°,120°,150°,180°)、3个坡度(10°,15°,20°)和3个流量(5,7.5,10 L/min)组合条件下,开展室内放水冲刷试验。结果表明:(1)地表产流率随冲刷历时呈先增加后稳定的趋势,而含沙量和地表产沙率随冲刷历时均呈波动性减小趋势;(2)各岩石与坡面夹角下,地表产流率无显著差异(P＞0.05);但含沙量与地表产沙率均差异显著(P＜0.05),表现为含沙量和地表产沙率在60 ...

Shuitu Baochi Xuebao, 2020 基于试验站不同坡地措施（坡耕地和坡改梯）2016年和2017年的逐日降水、产流产沙数据，研究不同坡地措施和雨强下产流产沙规律特征，定量揭示坡改梯和坡耕地对产流产沙的影响。结果表明：（1）7月平均雨强I、最大雨强I30及坡地产流量最大，8月最大雨强I60与坡地产沙量最大，表明坡地产流产沙高峰期与雨强高峰期一致。（2）春夏两季产流、产沙量与I、I30和I60相关性显著（超过95%置信度检验）。其中坡耕地产流产沙量与I、I30、I60的相关系数整体高于坡改梯。春夏季坡耕地产沙量分别是坡改梯的3.91，7 ...

Integrative Conservation, Volume 4, Issue 3, Page 393-404, September 2025.We studied the challenges in human‐wildlife coexistence in Abohar wildlife sanctuary and the surrounding landscape in Punjab, India. We found that the local people's unique intrinsic motivation for conservation and the traditional approaches to conservation are no longer sufficient.

Combating infections under siege: Healthcare challenges amidst the military assault in Gaza
World Medical &Health Policy, Volume 17, Issue 1, Page 188-213, March 2025.Abstract The ongoing Israeli military assault on Gaza has caused a devastating collapse of healthcare infrastructure, resulting in an unprecedented surge in infectious diseases. The destruction of sanitation systems, restrictions on medical supplies, and displacement of civilians have created an environment conducive to the rapid spread of waterborne ...
