Layered gravel soil slope stability of a waste dump considering long-term hard rain [PDF]
, 2016 In order to examine the effect of long-term hard rain on the layered gravel soil slope stability of a waste dump, the for-mula derivation relating natural water content, natural unit weight and natural volumetric water content was conducted to help to ...

高寒区多源降水产品精度与水文模拟效果评估——以雅鲁藏布江流域和拉萨河流域为例
Shuitu Baochi Xuebao, 2023 卫星降水产品在缺资料地区开展水文气象研究及径流模拟中发挥着至关重要的作用,然而卫星降水产品的精度可能会影响径流模拟效果。采用多种统计指标和VIC水文模型综合评估5种卫星降水产品(CMORPH-BLD、GSMaP_Gauge、CMFD、MSWEP和PERSIANN-CDR)在雅鲁藏布江流域的精度和拉萨河流域的水文模拟效果。结果表明:(1) CMORPH_BLD和GSMaP_Gauge在少雨季存在低估,CMFD在少雨季与观测值具有很好的一致性。MSWEP和PERSIANN-CDR在多雨季和少雨季存在高估 ...

Conservation Biology, Volume 39, Issue 4, August 2025.Abstract Marine protected and conserved areas (MPCAs) are promoted as an ecosystem‐based adaptation (EbA) approach to increase community and ecosystem resilience to climate change. However, traditional approaches to MPCA design typically do not consider climate risk or habitat condition under a climate threat.

运用Gash修正模型对祁连山北麓中段青海云杉林降水截留的模拟
Shuitu Baochi Xuebao, 2020 选择祁连山北麓中段排露沟流域青海云杉林为研究对象，基于2019年生长季（5—9月）降水截留观测数据、气象数据和林地调查资料，对其降水截留过程进行分析，运用Gash修正模型模拟青海云杉林降水截留过程。结果表明：研究期间林外大气降雨总量为418.7 mm，降雨主要为中、小雨。穿透雨量、树干茎流量、林冠截留量分别为284.5，6.7，127.5 mm，占大气降雨总量的比例分别为67.94%，1.60%，30.46%。根据Gash修正模型模拟结果，穿透雨量、树干茎流量、林冠截留量值分别为302.2，3.7 ...

Integrative Conservation, Volume 3, Issue 3, Page 168-182, September 2024.Using long‐term field data, we examined the impact of severe droughts on the health, reproductive success, and behavior of the critically endangered Verreaux's sifaka (Propithecus verreauxi) in Madagascar's seasonally dry tropical forest. Despite reduced availability of high‐quality foods, sifaka exhibited stable body condition and reproductive success,
