In the past 10 years, the pavement infrastructure strongly supports the rapid development of the global social economy. New theories, new methods,new technologies and new materials related to pavement engineering are emerging.Deterioration of pavement infrastructure is a typical multi-physics problem. Because of actual coupled behaviors of traffic and environmental conditions, predictions of pavement service life become more and more complicated and require a deep knowledge of pavement material analysis. In order to summarize the current and determine the future research of pavement engineering, Journal of Traffic and Transportation Engineering(English Edition) has launched a review paper on the topic of "New innovations in pavement materials and engineering: A review on pavement engineering research 2021". Based on the joint-effort of 43 scholars from 24 well-known universities in highway engineering, this review paper systematically analyzes the research status and future development direction of 5 major fields of pavement engineering in the world. The content includes asphalt binder performance and modeling, mixture performance and modeling of pavement materials,multi-scale mechanics, green and sustainable pavement, and intelligent pavement.Overall, this review paper is able to provide references and insights for researchers and engineers in the field of pavement engineering.

Yue Li,Yougui Song,Dimitris G.Kaskaoutis,Jinbo Zan,Rustam Orozbaev,Liangcheng Tan,Xiuling Chen[2](2021)在《Aeolian dust dynamics in the Fergana Valley, Central Asia, since ~30 ka inferred from loess deposits》文中提出Knowledge of the interactions among atmospheric dynamics, dust emissions and climate system is essential to understand the physical mechanisms for the dust lifecycle, their role in loess formation as well as the predictions of future dust concentration. However, these issues still remain relatively poorly known in Central Asia(CA). The extensive loess deposits on the CA pediments provide a promising archive to explore atmospheric dust dynamics and climatic conditions in the past and their association with loess formation. This study investigates the granulometric and magnetic properties of a loess section(named Osh section) in the Fergana Valley, which provides a sensitive record of atmospheric dust dynamics since 30 ka based on radiometric(AMS14C) dating. The frequency-dependent magnetic susceptibility(χfd) and the mean grain size are used to reconstruct the broadscale effective moisture and summer atmospheric dynamics pattern in CA, respectively. The results show that the precession forcing exerts a huge influence on the wind-regime variabilities in CA, but with different physical processes under the impact of the Northern Hemisphere ice sheet(NHIS) before and after 15 ka. The origin of the sedimentation rate variations in the Osh loess is also linked to the NHIS-modulated changes of the atmospheric circulation patterns. Either the strengthened westerlies or the increased surface roughness from higher vegetation cover in loess-deposition areas have significantly accelerated the loess accumulation. As a result, these complicated influence factors of sedimentation rate change in the Osh loess section, especially during the Holocene epoch, may hamper accessibility of the authentic dust emission flux and atmospheric dust concentration in CA.

QI Yu-han,PAN Mei-hui,HAO Ze-wen,YANG An-na,XUE Wen-xuan[3](2021)在《Variations in aeolian landform patterns in the Gonghe Basin over the last 30 years》文中提出Wind erosion, or the transportation and deposition of sand into desert dunes and aeolian loess, is one of the most important aeolian activities. The progression of aeolian landforms expands arid and barren landscapes, leading to the degradation of adjacent areas. The Gonghe Basin, as a typical plateau with abundant sand sources, is highly sensitive to changes in the local climate conditions. In order to quantify the spatial-temporal variations in the aeolian landforms in the Gonghe Basin, we conducted field surveys and also analyzed twelve remote sensing(Landsat5 TM and Landsat8 OLI) images that sample the Gonghe Basin from 1989 to 2019. In the Gonghe Basin, we identified aeolian landforms such as climbing dunes on the windward slopes of the foothills, checkerboard dunes in the southeastern part of the basin, flat dunes, parabolic dunes and crescent dunes on the east and west sides of Longyangxia Reservoir, shrubby sandbanks on the valley slope in Shazhuyu, Tanggemu, and Indel, and sandy thickets at the bottom of the valley near the Dalian Sea, the Longyangxia Reservoir, and the tributaries of the Yellow River. From 1989 to 2005, the area of theaeolian regions expanded by 816.7 km2, with an annual conversion rate of 0.05%. From 2015 to 2019, the area of the aeolian regions shrunk by 2411.9 km2, with an annual conversion rate of-0.15%.The number and size of the fixed and semi-fixed dunes(e.g. the shrubby sandbanks on the valley slope and the sandy thickets at the bottom of the valley) were more stable than those of the mobile dunes(e.g. the checkerboard dunes, the flat dunes, the crescent dunes, the parabolic dunes, and the climbing dunes). The fixed and semi-fixed dunes were arranged in an irregular ring shape, and the location of the center of gravity of this ring did not change significantly from 1989 to 2019; in this time, the mobile dunes migrated to the northwest.

Lixin CHEN,Yun ZHANG,Zhaochen KONG[4](2021)在《Airborne pollen patterns and their relationship with meteorological factors in the Betula microphylla-dominated wetland of Ebinur Lake, Xinjiang, China》文中研究指明Airborne pollen is indicative of vegetation and climatic conditions. This study investigates airborne pollen trapping in the Betula microphylla-dominated wetland of Ebinur Lake in Northwestern China from September 2012 to August 2015 using Pearson correlation analysis and the Hybrid Single-particle Lagrangian Integrated Trajectory model. Higher temperatures and moderate precipitation during the flowering period facilitated an increase in birch pollen with more exotic spruce pollen carried from the Tianshan Mountains by airflows, leading to the highest arbor pollen concentrations from September 2012 to August2013. Peak pollen concentrations from September 2013 to August 2014 were possibly due to an increase in herbaceous pollen resulting from higher temperatures, lower precipitation and more exotic pollen from the desert of southwest Ebinur Lake and Central Asia in summer and autumn. Between September 2014 and August 2015, unfavorable climate conditions in summer and autumn decreased the pollen dispersal of xerophytes such as Artemisia and Chenopodiaceae, with little pollen transported from the Kazakh hilly area in late summer, resulting in the lowest pollen concentrations. Climatic parameters and air mass movements both greatly affected the atmospheric pollen concentration. The results provide information concerning the dispersion and distribution of birch pollen, paleoenvironmental reconstruction and wetland conservation.

福法纳(Mohamed Lamine Fofana)[5](2021)在《SMD露天矿粉尘排放对环境的影响与减排技术研究》文中研究说明从采矿历史的最早几个小时开始,矿物市场参与者就一直在努力满足对矿物的需求。为了继续满足当前和将来的需求,矿山数量已经并将继续增加。地雷数量的增加,虽然对国家发展有利,但却是通过造成环境影响而实现的,这使当今的人们相信地雷有害无益。露天和地下采矿方式均会影响环境,但露天矿的影响(特别是与粉尘排放有关)的影响要大于地下。露天煤矿排放的粉尘会影响空气,水,土壤和生物多样性的质量,如果无法找到解决办法,这可能会导致即使不是不可能的情况下,周围居民的地雷也将非常困难。为了解决这个问题,有必要知道可以帮助有效控制粉尘的粉尘排放源。本文以SMD露天矿为研究背景。首先,根据对周围环境及其要素和人口健康的分析,确定了粉尘影响。excel用于分析获得的数据并制作其图形。其次,根据不同的采矿作业,总结了露天矿生产各方面扬尘的成因和扬尘的一些来源。列出了每个环节中粉尘排放的比例,并确定了本文的核心内容。Power Point软件用于图解每个已识别粉尘排放源的粉尘排放过程,以便对粉尘排放源进行详细说明。高速相机用于在SMD上拍摄采矿作业的照片和视频。这使得确定排放源和排放情况成为可能。第三,研究了SMD露天矿的粉尘控制技术,并提出了一些建议,以帮助他们改进粉尘控制技术。最后,研究区域的条件和矿山粉尘排放控制的一些技术。在这些研究过程中,根据研究区域的条件分析了粉尘控制技术的效率,技术经济性和环境方面,以便找到适合SMD的技术。根据研究区域的条件,向SMD提出了卡车速度控制以及加工厂和输送机覆盖范围的控制技术,作为控制粉尘排放的良好技术。本文的结论可以为矿山粉尘排放的控制提供理论和实践参考。本文包括38个数字,13个表格和73个参考文献。

Fernandes Dearlyn Mario[6](2020)在《氨基酸示踪中印热带河流沉积物和悬浮颗粒物中有机质的保存、组成和转化》文中研究说明陆源有机物通过河流从陆地向海洋迁移,是全球生物地球化学循环(碳、氮等元素)的重要组成部分,这些关键元素的输运和转化对局地地貌、人为干扰和全球气候变化极为敏感,因此陆海界面的物质输送转化的相关研究,将有助于认识全球变化背景下关键元素的源汇行为和控制因素分析。此前,相关研究更多关注有机碳相关过程,对有机氮的输送和转化以及控制因素分析相对薄弱,而有机氮更是在营养循环中起着重要作用,对近海初级生产力和生态系统健康有重大支持。陆海界面的有机氮来源、分布和影响因素的研究也将有助于今后预测其对全球营养盐生物地球化学循环的影响和贡献。研究表明,氮的生物地球化学循环受到自然因素和人为因素的影响,自然因素包括自然地貌特征、气候变化引起的降雨变化(极端洪水、气旋、台风及干旱),以及人为活动(如建造水坝)、土地利用模式的改变(为农业、工业化、城市化而砍伐森林)等,而这些因素和活动对热带地区的影响了解还很有限。热带地区的水生和陆生生态系统正在经历这些全球环境变化(土地利用变化和气候变化)的强烈影响,因此,小型热带河流系统是理想的研究环境,因为它们具有强烈的时空特征和更敏感的响应。氨基酸作为组成蛋白质的基本单元,在陆生及水生生物体中是有机氮最大的储库。开展河口及海洋中氨基酸组分的研究,将有助于揭示有机氮的来源、循环及生物地球化学行为。印度和中国都是拥有庞大人口的发展中国家,正在经历气候变化(风暴和干旱频率增加)和人类活动(土地使用模式的变化、水坝建设、日益增长的城市化和森林砍伐)的影响。迄今为止、对印度和中国热带小河流生物地球化学过程的了解并不多、尤其是河流氨基酸的来源和组成、运输和转化方面的研究很有限。因此,本论文的研究重点是识别印度西海岸热带河流和海南岛热带河流中氨基酸的时空分布和转化特征。利用先进的地球化学技术和同位素(元素和同位素比值及生物标志物)以及其他辅助参数,对印度和中国选定的热带小河系的氨基酸组成、转化和控制其迁移的因素进行了深入的研究。简要地说,本论文的研究目的如下:1.中印典型小河流和河口沉积物和颗粒物中的有机氮组成和转化的信息;2.从时间和空间上确定控制有机氮输送和转化的因素;3.分析地貌学(河流牛轭弯)和降水变化(季节性和台风活动)和人为活动(土地利用变化)对河流有机物组成和成岩作用的影响。为了实现研究目标,分别在季风期、季风前、季风后的季节对印度河的表层水和沉积物进行样品采集、同时在台风过后(2011年8月)以及非台风时期(2012年10月)分别采集南渡河表层水样品。使用先进的地球化学分析技术(元素组成和同位素比率)以及其它辅助参数(粒度、表面积)进行表征,同时测定生物标记物(氨基酸L-和D-对映异构体)、详细研究了印度和中国特定热带小河流体系中有机质的组成、转化及其控制因素。本论文选择了印度Netravati和Narmada河流,采集了其河流及河口区颗粒有机物和表层沉积物,测定了整体性质参数(总体含量,同位素及比表面积等),以及沉积物中氨基酸组成(包括其对映异构体结构组成)。结果显示:沉积物中氨基酸的对映异构体组成在Netravati河流中有明显的季节性组成变化和不同程度的降解特征,而Narmada River的沉积物的差异则主要体现在空间变化。在两条河流的表层沉积物中,均检出较高浓度的D型氨基酸,显示了其细菌来源的主要贡献,此外,来自人文活动的贡献可能不容忽视。其中D型精氨酸在所有D型氨基酸中含量是最高的,可能是由于细菌的胞外分泌物贡献及沉积物粘土成分的吸附作用而形成的保存效应。在对Netravati河流沉积物中氨基酸时空组成的细致分析中发现,基于氨基酸组成估算的降解指数(DI)在河流牛轭湾处枯水期间明显更负,表明有降解程度高的物质在此处的累积,体现了局部地貌环境在枯水期间其促淤作用使得有机物的成岩作用被增强。相比之下,在西南季风丰水期间,小河流作为快速冲刷通道,其在旱季积累的有机物被冲刷和重新分散。此外,γ-氨基丁酸与有机物载荷比例(OC:SA)呈负相关,酪氨酸与OC:SA比例则呈正相关,进一步说明不同氨基酸在有机物降解过程中的控制效应差异。来自Netravati和Narmada River的沉积物研究结果深化了地貌环境(牛轭/河流蜿蜒)的作用、降雨量变化对在热带河流中的自然氮循环影响的认知。论文选择印度西部Zuari River及河口区悬浮颗粒物(SPM)中氨基酸的来源和归宿展开了研究。不同季节的对比发现,其众多分析参数含量却没有观察到显着差异。但是盐度、颗粒有机碳、同位素比值、谷氨酸、丝氨酸、丙氨酸、酪氨酸、亮氨酸和D型天冬氨酸的空间变异性显着,暗示了源区贡献的潜在差异性。在季风后期间,POC含量比较低且显示来自混合来源的输入特征。同位素成分显示河口地区的样本比河流地区的样品具有相对较正的数值,这表明除了河流浮游生物和陆地C3植物碎屑的贡献外,还有海洋浮游生物的贡献影响。D型氨基酸如D型丙氨酸、D型天冬氨酸、D型谷氨酸、D型丝氨酸和D型精氨酸,及甘氨酸和非蛋白质氨基酸(y-氨基丁酸,GABA)的存在表明细菌来源对该区域有机碳和氮库的贡献显着。在季风季节和季风后季节,河口地区的有机物相对于河流地区来说有更高的生物活性,在季风季节前则观测到降解程度高的有机物成分。使用主成分分析来确定影响有机物的来源和因素表明,可提取5个因子,解释了总方差的84.5%。第一组分占方差的27.1%,表明潮汐的影响占优势;而第二组分则体现了异养细菌的贡献,主要影响氨基酸组成。根据研究结果,论文明确了Zuari River河口最大浑浊度(ETM)对颗粒有机物的来源和分布的控制作用。在中国海南岛南渡河的颗粒有机物的氨基酸其总浓度大约在0.1-1.1毫克每升,其含量和降解参数存在季节差异。结果表明,在2011年8月(台风)活动期间,南渡河颗粒物的降解状况明显增高。此外,从南渡河氨基酸组成、D/(D+L)比例和颗粒有机物含量可以推断,细菌过程极大程度改变了有机物结构。而较高的氨基酸总量的碳产率表明可能是多种来源造成的,包括维管束植物、浮游生物(海洋和河流)生产和土壤淋滤等。而两个季节观测到的部分氨基酸(丝氨酸、甘氨酸、异亮氨酸等)的显着变化,表明其在早期成岩作用中被优先使用。因此,通过这些中印的小河流体系中氨基酸行为分析发现,氨基酸在各个河流表现为不同的时空分布特征,与不同河流系统的地貌结构及流域中物源组成紧密相关,有机氮的生物可利用性取决于河流和河口区的保存和改造能力。这项研究提供了关于不同河流子系统的悬浮颗粒物和沉积环境中的氨基酸组成和转化的基础数据,并细化了季风影响在热带小河流的差异,弥补了中印小河流中有机氮对地貌和气候变化的响应(迁移和改造)的相关认知。

BALA HISHAM SHARIF[8](2020)在《生物气候设计与建筑设计的研究》文中提出生态的与环境和谐相处的建筑不仅是建筑领域关注的,我们再做建筑设计时,要尊重自然并推进自然人化的进程,同时获得良好的自然、经济和生态综合效益。生物气候学设计方法可以为建筑技术的发展提供基本方向,在一定程度上有助于我国建筑师结合本国经济、技术水平,客观分析特定地区环境,本研究旨在为建筑师提供一个宏观的气候概念,并为建筑和城市空间的生物气候设计总结实用、经验和技术方法。本研究采用文献分析法、横向比较法、综合分析法相结合。通过对国内外研究动态的分析,可以看出我国生物气候设计理论发展中存在的问题。同时,阐明生物气候建筑的概念,阐明生物气候建筑的定义、内涵及相关概念,以及生物气候建筑与生态建筑等概念的联系与区别,建立完整、系统的理论体系。结合区域生物气候设计策略的研究,针对夏热冬冷地区的特殊气候特点,研究了适合夏热冬冷地区的生物气候设计策略等。

阿玛度(Amadou TOURE)[9](2020)在《评估水源和使用点的水质:西非马里SEGOU地区PELENGANA公社的案例研究》文中进行了进一步梳理水是具有多种用途的珍贵和必要的自然资源。确保水源和使用点水的安全,在世界上从公共供水中收集饮用水的地区,这一点很重要。用于食品或卫生的水需要优良的理化性质和微生物质量。为了评估马里塞古地区农村社区,特别是佩伦卡纳公社农村社区水源和用水点的水质及其与健康的关系,对不同常用水源(包括地表水、浅井、挖井、钻孔、手动泵、家用容器和水泥池)的采集水样进行了理化性质和细菌学分析。为了跟踪不同季节的参数变化,在旱季和雨季分别采集了样品。这项研究还旨在评估消费者对水质的看法,并确定与水质恶化有关的因素,如水的储存、家庭人口统计、卫生和卫生习惯。这些数据是通过卫生调查、水质测试、家庭调查、文件分析、重点小组讨论和关键的信息提供者访谈收集的,目的是确定马里农村地区家庭安全、无障碍、可持续、成本效益高和可接受的供水模式。采用多管发酵技术测定饮用水微生物(总大肠菌群、粪大肠菌群、粪肠球菌和大肠杆菌计数)质量。同时测定了饮用水的电导率、浊度、pH和TDS、TSS、硝酸盐、亚硝酸盐、磷酸盐、氯化物、BOD5、Zn2+、F-、As、Hg、Cu、Cd、Pb、Mn、Cr、Fe 的含量。采用方差分析(ANOVA)和Duncan多重比较等多种统计分析方法,对收集的数据和水样的理化性质以及微生物指标进行了分析。将世界卫生组织(世卫组织,WHO)指南或其他值(GVs)以及美国公共卫生(USPH)饮用水质量标准作为基准。这项研究是在一些使用各种饮用水资源的农村进行的。研究结果表明,大量选定水源的水质理化性质和细菌学指标均较差。结果显示,来自不同水源的水样硝酸盐氮(NO3-N)的浓度超过了美国环境保护署(US-EPA)规定的10 mg/L,以及世界卫生组织的饮用水质量指南(WHO GDWQ)(11 mg/L)。这同样适用于重金属,如Cd、Pb和Fe,其浓度在某些地方超过其允许限值。此外,除不同钻孔的水样外,在所有选定的水源中均检测到总大肠菌群和大肠杆菌,表明水源受到粪便污染。某些水源的理化参数结果表明,硝酸盐、磷酸盐、铁、镉和铅的含量高于可接受的限值,特别是在潮湿时期。从细菌学上,对两个研究时期的细菌分布进行了比较分析,结果表明:雨季细菌数量多于旱季。此外,调查结果还表明,由于地表水和井水的水源质量差,以及使用点的微生物污染(家用容器和水泥池),所有使用点的水对人类的消费都是不安全的。后者可归因于不卫生的环境、不良的卫生习惯或不良的用水行为。总的来说,在旱季细菌的数量略有减少。这种污染无疑对饮用这些水的人的健康构成重大损害。为了减少与水有关的疾病,应提供安全和充足的水、卫生教育以及关于用水行为的教育。提供改进的供水系统并不能确保饮用水对人类的消费是安全的,应考虑使用点水处理等措施,以确保在水源和使用点提供的饮用水对人类的消费具有微生物安全性。

哈瓦(DIAKITE HAWA)[10](2020)在《马里SEGOU地区PELENGANA居民家庭用水管理研究》文中研究表明在马里的许多乡村地区,人们最关心的一个问题是如何更容易地获得安全而又可持续利用的水资源。与世界上许多国家一样,马里同样面临着多种因素造成的水资源短缺问题。本篇论文主要研究了马里Segou地区Pelengana镇居民家庭用水管理问题,包括家庭用水量、水质、水的来源及其它方面。为了解决这些问题,许多国际性和区域性以及当地供水发展组织正在积极努力,以帮助当地居民获得安全而又持久的水资源。2002年,为了促进Segou区域各供水组织建立广泛的合作关系,马里发布了“西非水倡议书(WAWI)”。马里农村地区的特点是人口拥挤、居住条件差、水资源短缺、卫生设施不足,这种生存环境导致了水传播疾病的大量发生。因此,安全的饮用水资源以及良好的卫生条件尤为重要。然而,来自Pelengan镇各卫生中心的数据显示,水传播疾病是影响居住区域内各流民营地居民健康的主要疾病。为了解决这个问题,许多政府和非政府组织正通力合作,致力于提高用水管理质量。本论文的研究目的是通过调查分析参与者家庭日常生活用水量和节约用水实际情况,以及对水质进行的微生物分析结果,提出改善用水管理状况的解决方案。Pelengana镇的数据收集采用了实地调查、直接访谈、问卷调查、调查地观测和水样提取等方法。本研究共有来自Pelengana镇三个村庄的480名居民参与,其中,女性280名,男性200名。由于13份问卷不够完整而剔除在外,因此,最终统计结果来自于467份完整问卷,其中,女性272名,男性195名。首先,通过利用方差分析LSD检验方法及结构方程模型对数据进行分析,结果表明,女性的用水量(人均90.17L/d)是男性用水量(42.43 L/d)的两倍多,主要是蔬菜和花卉种植方面的农业用水(23.87±8.74 L/d),厨房用水(14.10±4.82 L/d),洗衣(12.50±4.57 L/d),以及饮用和个人卫生用水(11.40±2.39 L/d);至于家庭庭院清洁、淋浴和饲养牲畜等方面用水,总体上看,与男性相比,女性受访者会使用更多的水。其次,通过对常用水源—特别是Pelengana镇流民居住营地的井眼、手动泵、地表水、家用容器、水井和水泥水库等水源进行了水质微生物分析,结果显示,三种指示菌的数量(总大肠菌群(48.7%),粪便大肠菌群(100%)和粪便肠球菌(37.01%))都超过了饮用水允许的限值,最高的指示菌总数达到了 1800TC/100ml水;分离得到的肠道细菌包括大肠杆菌(25.7%)、肠球菌(21.91%)、芽孢杆菌属(16.72%)、肠杆菌属(4.56%)和柠檬酸杆菌属(3.91%)。最后,在调查分析结果的基础之上,论文中提出了改善Pelengana镇用水管理状况的一些建议与对策。
