Integrative Conservation, Volume 3, Issue 2, Page 87-103, June 2024.Some extinctions can be prevented if impediments to protection of threatened species are overcome. Policies and practices have failed endangered species and biodiversity conservation is fraught with impediments such as rhetorical adoption, policy dismantling, circumvention of legislative obligations, and deliberate ignorance of scientific evidence ...

Shuitu Baochi Xuebao, 2016 为揭示雨强对喀斯特坡耕地养分流失的影响，运用可调坡度、地下孔（裂）隙度试验钢槽装填土石模拟喀斯特裸露坡耕地，采用人工模拟降雨的方法研究不同雨强下喀斯特裸坡径流养分流失特征。结果表明：（1）雨强为15，30 mm/h时地表不产流，雨强50 mm/h时地表有产流；试验雨强下地下孔（裂）隙均有径流产生。（2）地表径流中全氮和全钾流失量均随雨强增大而增大，全磷流失量则先增大后减小；地下径流中全氮流失量随雨强增大呈先增大后减小趋势，全钾流失量与雨强正相关，全磷流失量与雨强关系不明显。（3）雨强为30，50 mm ...

Wildlife Letters, Volume 2, Issue 2, Page 83-89, June 2024.In this study, we show that environmental food availability influences wildlife detection probability when using food baits. We sampled small mammals in Borneo with live traps baited with fruit before, during and after the rainforest experienced a mast fruiting event, which drastically altered environmental food availability.

Shuitu Baochi Xuebao, 2017 利用遂宁水土保持试验站5个径流小区1984—2015年次降雨和径流输沙数据，基于降雨过程定量划分出4种雨型，分析了雨型对不同坡度坡耕地产流产沙的作用。结果表明：径流深与各时段最大雨强均呈极显著相关（p＜0.01），随着坡度的增加，最大相关系数所对应的雨强时段越短；冲刷量均与I平均呈极显著相关，且相关系数最大。径流深、冲刷量与雨强拟合关系均为幂函数，分别为“凸型”和“凹型”增函数，且拟合度区间分别为[0.79，0.88]和[0.90，0.97]，说明冲刷量和雨强的关系更密切 ...

Impacts of storm event on DOM composition and flux in two Jiulong Tributaries with different watershed features [PDF]
, 2016 通过调查2014年7月"麦德姆"台风影响期间福建九龙江北溪(流域以林地为主)和西溪(农业流域和城市背景)下游定点站DOM的时间序列,测定样品的DOC含量及其吸收光谱和三维荧光光谱,以评估不同流域背景对河流DOM动力学降雨响应的差异性,并为流域-河口系统的一体化管理提供重要参考。降雨期间,两条河流DOC浓度、吸收系数aCDOM(350)以及总荧光强度均随径流量升高而增大,并在水位下降期持续增加,且西溪增加量明显高于北溪,说明受人类活动扰动大的流域河流有机质对暴雨事件的响应更为灵敏 ...

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 ...

Conservation Biology, Volume 38, Issue 3, June 2024.Abstract Reintroduced populations are typically considered to progress through establishment, growth, and regulatory phases. However, most reintroduction programs do not monitor intensively enough to test this conceptual model. We studied population indices derived from track activity of 4 threatened species (greater bilby [Macrotis lagotis], burrowing

Shuitu Baochi Xuebao, 2011 弃土场是开发建设项目中最重要的水土流失来源之一。以辽宁省沈阳市某电厂剥离表土临时堆土为对象,研究棕壤地区开发建项目设弃土的流失规律。试验在沈阳农业大学水利学院综合试验基地的人工模拟降雨试验大厅内进行,共设5个雨强、5个坡度,雨强分别为0.38,0.64,1.05,1.24,1.50 mm/min,坡度分别设定为20°,25°,30°,35°,40°。研究结果表明,相同条件下,雨强越大坡面产流时间越短,坡面土壤水分入渗率随雨强的增加而增加,且雨强越大坡面初始入渗率越高;径流量随雨强的增加而增加 ...

Shuitu Baochi Xuebao, 2021 自然条件下降雨多以间歇形式出现，而坡面土壤侵蚀又是一个渐变发育的复杂过程。通过3个雨强（60，90，120 mm/h）、5个坡度（5°，10°，15°，20°，25°）下的15场室内模拟降雨，研究一、二次降雨条件下不同雨强、坡度及降雨量对红壤坡面径流和侵蚀过程的影响，探讨间歇降雨条件下坡面侵蚀发育过程及其主要影响因素的变化。结果表明：（1）二次降雨的产流时间相比一次降雨均提前，一次降雨径流总量受到雨强、坡度和降雨量的共同影响，15°坡度是径流总量变化的一个转折点，二次降雨时降雨量的作用减弱 ...
