1Measurements of the center-of-mass energies at BESⅢ via the di-muon process显示文摘From 2011 to 2014,the BESIII experiment collected about 5 fb^(-1) data at center-of-mass energies around 4 GeV for the studies of the charmonium-like and higher excited charmonium states.By analyzing the di-muon process e^+e^- → Yisr/fsr μ^+μ^-,the center-of-mass energies of the data samples are measured with a precision of 0.8 MeV.The center-of-mass energy is found to be stable for most of the time during data taking.麦迪娜 M.N.Achasov 艾小聪 O.Albayrak M.Albrecht D.J.Ambrose A.Amoroso 安芬芬 安琪 白景芝 R.Baldini Ferroli 班勇 D.W.Bennett J.V.Bennett M.Bertani D.Bettoni 边渐鸣 F.Bianchi E.Boger I.Boyko R.A.Briere 蔡浩 蔡啸 O.Cakir A.Calcaterra 曹国富 S.A.Cetin 常劲帆 G.Chelkov 陈刚 陈和生 陈海云 陈江川 陈玛丽 陈申见 谌炫 陈旭荣 陈元柏 程和平 褚新坤 G.Cibinetto 代洪亮 代建平 A.Dbeyssi D.Dedovich 邓子艳 A.Denig I.Denysenko M.Destefanis F.De Mori 丁勇 董超 董静 董燎原 董明义 杜书先 段鹏飞 范荆州 方建 房双世 方馨 方易 L.Fava F.Feldbauer G.Felici 封常青 E.Fioravanti M.Fritsch 傅成栋 高清 高鑫磊 高旭阳 高原宁 高榛 I.Garzia K.Goetzen 龚文煊 W.Gradl M.Greco 顾旻皓 顾运厅 管颖慧 郭爱强 郭立波 郭玥 郭玉萍 Z.Haddadi A.Hafner 韩爽 郝喜庆 F.A.Harris 何康林 T.Held 衡月昆 侯治龙 胡琛 胡海明 胡继峰 胡涛 胡誉 黄光明 黄光顺 黄金书 黄性涛 黄勇 T.Hussain 纪全 姬清平 季晓斌 季筱璐 姜鲁文 江晓山 蒋兴雨 焦健斌 焦铮 金大鹏 金山 T.Johansson A.Julin N.Kalantar-Nayestanaki 康晓琳 康晓珅 M.Kavatsyuk B.C.Ke P.Kiese R.Kliemt B.Kloss O.B.Kolcu B.Kopf M.Kornicer W.Kühn A.Kupsc J.S.Lange M.Lara P.Larin C.Leng 李翠 李澄 李德民 李飞 李峰云 李刚 李海波 李家才 李瑾 李康 李科 李蕾 李培荣 李腾 李卫东 李卫国 李晓玲 李小梅 李小男 李学潜 李志兵 梁昊 梁勇飞 梁羽铁 廖广睿 D.X.Lin(lin) 刘北江 刘春秀 刘栋 刘福虎 刘芳 刘峰 刘宏邦 刘欢欢 刘汇慧 刘怀民 刘杰 刘建北 刘觉平 刘晶译 刘凯 刘魁勇 刘兰雕 刘佩莲 刘倩 刘树彬 刘翔 刘玉斌 刘振安 刘智清 H.Loehner 娄辛丑 吕海江 吕军光 卢宇 卢云鹏 罗成林 罗民兴 T.Luo 罗小兰 吕晓睿 马凤才 马海龙 马连良 马秋梅 马天 马旭宁 马骁妍 F.E.Maas M.Maggiora 冒亚军 毛泽普 S.Marcello J.G.Messchendorp 闵建 R.E.Mitchell 莫晓虎 莫玉俊 C.Morales Morales K.Moriya N.Yu.Muchnoi H.Muramatsu Y.Nefedov F.Nerling I.B.Nikolaev 宁哲 S.Nisar 牛顺利 牛讯伊 馬鵬 欧阳群 S.Pacetti 潘越 P.Patteri M.Pelizaeus 彭海平 K.Peters J.Pettersson 平加伦 平荣刚 R.Poling V.Prasad 祁鸣 钱森 乔从丰 秦丽清 覃拈 秦小帅 秦中华 邱进发 K.H.Rashid C.F.Redmer M.Ripka 荣刚 Ch.Rosner 阮向东 V.Santoro A.Sarantsev M.Savrie K.Schoenning S.Schumann 单葳 邵明 沈成平 沈培迅 沈肖雁 盛华义 宋维民 宋欣颖 S.Sosio S.Spataro 孙功星 孙俊峰 孙胜森 孙勇杰 孙永昭 孙志嘉 孙振田 唐昌建 唐晓 I.Tapan E.H.Thorndike M.Tiemens M.Ullrich I.Uman G.S.Varner 王斌 王东 王大勇 王科 王亮亮 王灵淑 王萌 王平 王佩良 王思广 王炜 王维平 王雄飞 王雅迪 王贻芳 王亚乾 王铮 王志刚 王志宏 王至勇 T.Weber 魏代会 韦江波 P.Weidenkaff 文硕频 U.Wiedner M.Wolke 伍灵慧 吴智 夏磊 夏力钢 夏宇 肖栋 肖浩 肖振军 谢宇广 修青磊 许国发 徐雷 徐庆君 徐新平 严亮 鄢文标 闫文成 颜永红 杨海军 杨洪勋 杨柳 杨迎 杨永栩 叶梅 叶铭汉 殷俊昊 俞伯祥 喻纯旭 俞洁晟 苑长征 袁文龙 袁野 A.Yuncu A.A.Zafar A.Zallo 曾云 曾哲 张丙新 张炳云 张弛 张长春 张达华 张宏浩 章红宇 张佳佳 张杰磊 张敬庆 张家文 张建勇 张景芝 张坤 张磊 张学尧 张瑶 张宇宁 张银鸿 张亚腾 张宇 张正好 张子平 张振宇 赵光 赵京伟 赵静宜 赵京周 赵雷 赵玲 赵明刚 赵强 赵庆旺 赵书俊 赵天池 赵豫斌 赵政国 A.Zhemchugov 郑波 郑建平 郑文静 郑阳恒 钟彬 周莉 周详 周晓康 周小蓉 周兴玉 朱凯 朱科军 朱帅 朱世海 朱相雷 朱莹春 朱永生 朱自安 庄建 L.Zotti 邹冰松 邹佳恒 2016Chinese Physics C2016,40,6:61
2Study of BESIII trigger efficiencies with the 2018 J/ψ data显示文摘Using a dedicated data sample taken in 2018 on the J/ψpeak,we perform a detailed study of the trigger efficiencies of the BESIII detector.The efficiencies are determined from three representative physics processes,namely Bhabha scattering,dimuon production and generic hadronic events with charged particles.The combined efficiency of all active triggers approaches 100%in most cases,with uncertainties small enough not to affect most physics analyses.M.Ablikim M.N.Achasov P.Adlarson S.Ahmed M.Albrecht R.Aliberti A.Amoroso M.R.An Q.An X.H.Bai Y.Bai O.Bakina R.Baldini Ferroli I.Balossino Y.Ban K.Begzsuren N.Berger M.Bertani D.Bettoni F.Bianchi J.Bloms A.Bortone I.Boyko R.A.Briere H.Cai X.Cai A.Calcaterra G.F.Cao N.Cao S.A.Cetin J.F.Chang W.L.Chang G.Chelkov D.Y.Chen G.Chen H.S.Chen M.L.Chen S.J.Chen X.R.Chen Y.B.Chen Z.J Chen W.S.Cheng G.Cibinetto F.Cossio X.F.Cui H.L.Dai X.C.Dai A.Dbeyssi R.E.de Boer D.Dedovich Z.Y.Deng A.Denig I.Denysenko M.Destefanis F.De Mori Y.Ding C.Dong J.Dong L.Y.Dong M.Y.Dong X.Dong S.X.Du Y.L.Fan J.Fang S.S.Fang Y.Fang R.Farinelli L.Fava F.Feldbauer G.Felici C.Q.Feng J.H.Feng M.Fritsch C.D.Fu Y.Gao Y.Gao Y.Gao Y.G.Gao I.Garzia P.T.Ge C.Geng E.M.Gersabeck A Gilman K.Goetzen L.Gong W.X.Gong W.Gradl M.Greco L.M.Gu M.H.Gu S.Gu Y.T.Gu C.Y Guan A.Q.Guo L.B.Guo R.P.Guo Y.P.Guo A.Guskov T.T.Han W.Y.Han X.Q.Hao F.A.Harris H Hüsken K.L.He F.H.Heinsius C.H.Heinz T.Held Y.K.Heng C.Herold M.Himmelreich T.Holtmann Y.R.Hou Z.L.Hou H.M.Hu J.F.Hu T.Hu Y.Hu G.S.Huang L.Q.Huang X.T.Huang Y.P.Huang Z.Huang T.Hussain W.Ikegami Andersson W.Imoehl M.Irshad S.Jaeger S.Janchiv Q.Ji Q.P.Ji X.B.Ji X.L.Ji H.B.Jiang X.S.Jiang J.B.Jiao Z.Jiao S.Jin Y.Jin T.Johansson N.Kalantar-Nayestanaki X.S.Kang R.Kappert M.Kavatsyuk B.C.Ke I.K.Keshk A.Khoukaz P.Kiese R.Kiuchi R.Kliemt L.Koch O.B.Kolcu B.Kopf M.Kuemmel M.Kuessner A.Kupsc M.G.Kurth W.Kühn J.J.Lane J.S.Lange P.Larin A.Lavania L.Lavezzi Z.H.Lei H.Leithoff M.Lellmann T.Lenz C.Li C.H.Li Cheng Li D.M.Li F.Li G.Li H.Li H.Li H.B.Li H.J.Li J.L.Li J.Q.Li J.S.Li Ke Li L.K.Li Lei Li P.R.Li S.Y.Li W.D.Li W.G.Li X.H.Li X.L.Li Z.Y.Li H.Liang H.Liang H.Liang Y.F.Liang Y.T.Liang L.Z.Liao J.Libby C.X.Lin B.J.Liu C.X.Liu D.Liu F.H.Liu Fang Liu Feng Liu H.B.Liu H.M.Liu Huanhuan Liu Huihui Liu J.B.Liu J.L.Liu J.Y.Liu K.Liu K.Y.Liu Ke Liu L.Liu M.H.Liu P.L.Liu Q.Liu Q.Liu S.B.Liu Shuai Liu T.Liu W.M.Liu X.Liu Y.Liu Y.B.Liu Z.A.Liu Z.Q.Liu X.C.Lou F.X.Lu H.J.Lu J.D.Lu J.G.Lu X.L.Lu Y.Lu Y.P.Lu C.L.Luo M.X.Luo b P.W.Luo T.Luo X.L.Luo S.Lusso X.R.Lyu F.C.Ma H.L.Ma L.L.Ma M.M.Ma Q.M.Ma R.Q.Ma R.T.Ma X.X.Ma X.Y.Ma F.E.Maas M.Maggiora S.Maldaner S.Malde Q.A.Malik A.Mangoni Y.J.Mao Z.P.Mao S.Marcello Z.X.Meng J.G.Messchendorp G.Mezzadri T.J.Min R.E.Mitchell X.H.Mo Y.J.Mo N.Yu.Muchnoi H.Muramatsu S.Nakhoul Y.Nefedov F.Nerling I.B.Nikolaev Z.Ning S.Nisar S.L.Olsen Q.Ouyang S.Pacetti X.Pan Y.Pan A.Pathak P.Patteri M.Pelizaeus H.P.Peng K.Peters J.Pettersson J.L.Ping R.G.Ping R.Poling V.Prasad H.Qi H.R.Qi K.H.Qi M.Qi T.Y.Qi T.Y.Qi S.Qian W.-B.Qian Z.Qian C.F.Qiao L.Q.Qin X.S.Qin Z.H.Qin J.F.Qiu S.Q.Qu K.H.Rashid K.Ravindran C.F.Redmer A.Rivetti V.Rodin M.Rolo G.Rong Ch.Rosner M.Rump H.S.Sang A.Sarantsev Y.Schelhaas C.Schnier K.Schoenning M.Scodeggio D.C.Shan W.Shan X.Y.Shan J.F.Shangguan M.Shao C.P.Shen P.X.Shen X.Y.Shen H.C.Shi R.S.Shi X.Shi X.D Shi W.M.Song Y.X.Song S.Sosio S.Spataro K.X.Su P.P.Su F.F.Sui G.X.Sun H.K.Sun J.F.Sun L.Sun S.S.Sun T.Sun W.Y.Sun X Sun Y.J.Sun Y.K.Sun Y.Z.Sun Z.T.Sun Y.H.Tan Y.X.Tan C.J.Tang G.Y.Tang J.Tang J.X.Teng V.Thoren I.Uman B.Wang C.W.Wang D.Y.Wang H.J.Wang H.P.Wang K.Wang L.L.Wang M.Wang M.Z.Wang Meng Wang W.Wang W.H.Wang W.P.Wang X.Wang X.F.Wang X.L.Wang Y.Wang Y.D.Wang Y.F.Wang Y.Q.Wang Y.Y.Wang Z.Wang Z.Y.Wang Ziyi Wang Zongyuan Wang D.H.Wei P.Weidenkaff F.Weidner S.P.Wen D.J.White U.Wiedner G.Wilkinson M.Wolke L.Wollenberg J.F.Wu L.H.Wu L.J.Wu X.Wu Z.Wu L.Xia H.Xiao S.Y.Xiao Z.J.Xiao X.H.Xie Y.G.Xie Y.H.Xie T.Y.Xing G.F.Xu Q.J.Xu W.Xu X.P.Xu F.Yan L.Yan W.B.Yan W.C.Yan Xu Yan H.J.Yang H.X.Yang L.Yang S.L.Yang Y.X.Yang Yifan Yang Zhi Yang M.Ye M.H.Ye J.H.Yin Z.Y.You B.X.Yu C.X.Yu G.Yu J.S.Yu T.Yu C.Z.Yuan L.Yuan X.Q.Yuan Y.Yuan Z.Y.Yuan C.X.Yue A.Yuncu A.A.Zafar Y.Zeng B.X.Zhang Guangyi Zhang H.Zhang H.H.Zhang H.Y.Zhang J.J.Zhang J.L.Zhang J.Q.Zhang J.W.Zhang J.Y.Zhang J.Z.Zhang Jianyu Zhang Jiawei Zhang L.Q.Zhang Lei Zhang S.Zhang S.F.Zhang Shulei Zhang X.D.Zhang X.Y.Zhang Y.Zhang Y.H.Zhang Y.T.Zhang Yan Zhang Yao Zhang Yi Zhang Z.H.Zhang Z.Y.Zhang G.Zhao J.Zhao J.Y.Zhao J.Z.Zhao Lei Zhao Ling Zhao M.G.Zhao Q.Zhao S.J.Zhao Y.B.Zhao Y.X.Zhao Z.G.Zhao A.Zhemchugov B.Zheng J.P.Zheng Y.Zheng Y.H.Zheng B.Zhong C.Zhong L.P.Zhou Q.Zhou X.Zhou X.K.Zhou X.R.Zhou A.N.Zhu J.Zhu K.Zhu K.J.Zhu S.H.Zhu T.J.Zhu W.J.Zhu W.J.Zhu Y.C.Zhu Z.A.Zhu B.S.Zou J.H.Zou 2021Chinese Physics C2021,45,2:33
3On the combined effect of soil fertility and topography on tree growth in subtropical forest ecosystems—a study from SE China显示文摘Aims The aim of our research was to understand small-scale effects of topography and soil fertility on tree growth in a forest biodiversity and ecosystem functioning(BEF)experiment in subtropical SE China.Methods Geomorphometric terrain analyses were carried out at a spatial resolution of 5×5 m.Soil samples of different depth increments and data on tree height were collected from a total of 566 plots(667 m2 each).The soils were analyzed for carbon(soil organic carbon[SOC]),nitrogen,acidity,cation exchange capacity(CEC),exchangeable cations and base saturation as soil fertility attributes.All plots were classified into geomorphological units.Analyses of variance and linear regressions were applied to all terrain,soil fertility and tree growth attributes.Important Findings In general,young and shallow soils and relatively small differences in stable soil properties suggest that soil erosion has truncated the soils to a large extent over the whole area of the experiment.This explains the concurrently increasing CEC and SOC stocks downslope,in hollows and in valleys.However,colluvial,carbon-rich sediments are missing widely due to the convexity of the footslopes caused by uplift and removal of eroded sediments by adjacent waterways.The results showed that soil fertility is mainly influenced by topography.Monte-Carlo flow accumulation(MCCA),curvature,slope and aspect significantly affected soil fertility.Furthermore,soil fertility was affected by the different geomorphological positions on the experimental sites with ridge and spur positions showing lower exchangeable base cation contents,especially potassium(K),due to leaching.This geomorphological effect of soil fertility is most pronounced in the topsoil and decreases when considering the subsoil down to 50 cm depth.Few soil fertility attributes affect tree height after 1-2 years of growth,among which C stocks proved to be most important while pH_(KCl)and CEC only played minor roles.Nevertheless,soil acidity and a high proportion of Al on the exchange complex affected tree height even after only 1-2 years growth.Hence,our study showed that forest nutrition is coupled to a recycling of litter nutrients,and does not only depend on subsequent supply of nutrients from the mineral soil.Besides soil fertility,topography affected tree height.We found that especially MCCA as indicator of water availability affected tree growth at small-scale,as well as aspect.Overall,our synthesis on the interrelation between fertility,topography and tree growth in a subtropical forest ecosystem in SE China showed that topographic heterogeneity lead to ecological gradients across geomorphological positions.In this respect,small-scale soil-plant interactions in a young forest can serve as a driver for the future development of vegetation and biodiversity control on soil fertility.In addition,it shows that terrain attributes should be accounted for in ecological research.Thomas Scholten Philipp Goebes Peter Kühn Steffen Seitz Thorsten Assmann Jürgen Bauhus Helge Bruelheide Francois Buscot Alexandra Erfmeier Markus Fischer Werner Härdtle Jin-Sheng He Keping Ma Pascal A.Niklaus Michael Scherer-Lorenzen Bernhard Schmid Xuezheng Shi Zhengshan Song Goddert von Oheimb Christian Wirth Tesfaye Wubet Karsten Schmidt 2017Journal of Plant Ecology2017,10,1:22

5Microstructural Evolution and Mechanical Behaviour of Metastable Cu-Zr-Co Alloys显示文摘Three different CueZreCo alloys, namely Cu40Zr37.5Co22.5, Cu42.5Zr45Co12.5and Cu49Zr49Co2, were obtained by rapid cooling. The microstructure and phase formation of as-cast rods with diameters of 2 mm are compared with those of the respective ingots. An increasing Co content stabilises the B2 CuZr phase and leads to the precipitation of a ternary CueZreCo phase. The variation of the cooling rate affects the size of the B2 dendrites as well as the volume fraction and the morphology of the interdendritic phases. The mechanical properties were determined in compression and all alloys show a certain plastic deformability despite the presence of several binary and ternary intermetallic phases. The deformation mechanisms are discussed on the basis of the microstructures and the constituent phases.S.Pauly K.Kosiba P.Gargarella B.Escher K.K.Song G.Wang U.Kühn J.Eckert 2014Journal of Materials Science & Technology2014,30,6:8
6氩等离子体表面凝固在支气管病学中的应用显示文摘氩等离子体表面凝固(argoplasmacoagulation,APC)是一种应用高频电流将电离的氢气(等离子体)无接触地热凝固组织的方法。由364例患者的前瞻性研究,表明APC是一种有效、安全的支气管肿瘤摘除和止血方法。它不仅可在局麻下由可曲支气管镜,而且也可在全麻下由硬质支气管镜进行,与激光相比,APC费用少,而止血效果更好,与其他方法合用,可丰富支气管介入内镜学手段。Reichle G Freitag L Kullmann HJ Prenzel R Macha HN Farin G 刘辉国 高亚东 华中科技大学同济医学院附属同济医院呼吸内科 2000国外医学(呼吸系统分册)2000,20,4:7

8风力机叶片三维模型颤振问题显示文摘颤振对风力机叶片有巨大破坏力,作为一种典型的气动弹性稳定性问题,在现代风力机的叶片设计中越来越受到重视。建立叶片三维叶型模型和整机振动结构模型,利用振型叠加法计算不同振动模态下的特征频率、阻尼比和振型,得出不同叶片结构参数与颤振的关系。结果表明,叶片型面质心和扭转中心的距离、拍打方向弯曲刚度和挥舞方向弯曲刚度对颤振发生有较大影响。王伟 廖明夫 Martin Kühn 2013噪声与振动控制2013,33,5:6
9睾丸主要血管或睾丸网旁取精点与取精成功率不具显著相关性:以220例非梗阻性无精子症患者行传统或显微睾丸取精术为例显示文摘采用传统与显微睾丸取精术相结合方式对220例梗阻性无精症患者行精子提取术,如果传统手术方式未见精子即为阴性取精位点,然后选取2—3个阴性取精位点行显微睾丸取精术。术中通过手术显微镜评价睾丸血管系统,同时记录阳性取精位点与睾丸血供的关系。总的精子获取率为58-2%,早期应用传统手术方式精子获取率为46.8%,而后行显微睾丸取精术则精子获取率增加11.7%。故显微睾丸取精术的应用可显著增加精子获取率(P=0.017),且在睾丸网或睾丸主要血管处并不能显著增加阳性取精位点。J Ullrich Schwarzer Heiko Steinfatt Heiko Steinfatt Manfred Schleyer Frank M Kōhn Klaus Fiedler2, Irene von Hertwig Gottfried Krüsmann Wolfgang Würfel 2013Asian Journal of Andrology2013,15,6:5

15The effects of 12 weeks of functional strength training on muscle strength,volume and activity upon exposure to elevated Gz forces in high-performance aircraft personnel显示文摘Background:Technological advancements in modern military and acrobatic jet planes have resulted in extraordinary psychophysiological loads being exerted upon flying personnel,including inducing neck and back pain.The purpose of this study was to examine the effects of 12 weeks of functional strength training on 1)the volume and strength of the neck and shoulder muscles and 2)muscular activity upon exposure to helmets of different masses and elevated Gz forces in a long-arm centrifuge in high-performance aircraft personnel.Methods:Eighteen participants underwent 12 weeks of functional strength training(n=12)or the control protocol(n=6)without additional strength training.Pre-and post-intervention tests included evaluations of isometric strength of the head extensor muscles,flexion,and lateral flexion and rotation,as well as magnetic resonance imaging(MRI)to measure the volume of the m.sternocleidomastoideus,m.trapezius,and deep neck muscles.Furthermore,during a long-arm centrifuge(+1.4 and+3Gz)protocol,the muscular activity levels of the m.sternocleidomastoideus,m.trapezius and m.erector spinae muscles were assessed without a flight helmet,with a helmet,and with a helmet and night vision goggles.Each participant’s perception of muscular strain was noted immediately after the long-arm centrifuge protocol.Results:The maximal isometric strength in all exercises and muscle volumes increased in the training group but not the control group(P<0.05).Relative muscle activity(%MVC)with a helmet decreased after the intervention in the training but not the control group(P=0.01).Relative muscle activity while wearing a helmet and night vision goggles was higher after intervention in the control group than in the training group(P<0.01).The perceived muscular strain of the neck muscles induced by the long-arm centrifuge did not differ between the groups.Conclusions:Twelve weeks of functional strength training improves the maximal isometric strength and volume of neck and shoulder muscles and leads to lower relative muscle activation upon exposure to elevated Gz forces in a long-arm centrifuge.Monika Rausch Frank Weber Sven Kühn Carla Ledderhos Christoph Zinner Billy Sperlich 2021Military Medical Research2021,8,4:4

18Plastic deformation of a Zr-based bulk metallic glass fabricated by selective laser melting显示文摘Fully amorphous Zr_(52.5)Cu_(17.9)Ni_(14.6)Al_(10)Ti_(5) bulk metallic glass(BMG) samples with a relative density exceeding 98% were fabricated via selective laser melting(SLM).High fracture stresses of around1700 MPa and a reproducible plastic strain of about 0.5% were obtained for cylindrical SLM samples.The analysis of the observed serrations during compressive loading implies that the shear-band dynamics in the additively manufactured samples distinctly differ from those of the as-cast glass.This phenomenon appears to originate from the presence of uniformly dispersed spherical pores as well as from the more pronounced heterogeneity of the glass itself as revealed by instrumented indentation.Despite these heterogeneities,the shear bands are straight and form in the plane of maximum shear stress.Additive manufacturing,hence,might not only allow for producing large BMG samples with complex geometries but also for manipulating their deformation behaviour through tailoring porosity and structural heterogeneity.L.Deng K.Kosiba R.Limbach L.Wondraczek U.Kühn S.Pauly 2021Journal of Materials Science & Technology2021,,1:2
19Estimation of Throughfall Erosivity in a Highly Diverse Forest Ecosystem Using Sand-Filled Splash Cups显示文摘Sand-filled splash cups were used to study the erosive power of rainfall and throughfall in the humid subtropics of Southeast China. The splash cup measurements yielded precise and reproducible results under both open field conditions and forest vegetation. The splash cups were exposed to specific forest stands of different ages and to selected species (Schima superba, Castanopsis eyrei, Daphniphyllum oldhamii, Lithocarpus glaber) in the Gutianshan (古田山) National Nature Reserve (GNNR). The results of the measurements under forest vegetation show that the erosive power of throughfall drops to be 2.59 times higher compared to the open field. This accentuates the importance of shrub, herb and litter layers in forest ecosystems to protect the soil against erosion. Coalescing drops from leaves and branches (drips) are responsible for this notable gain in erosive power. Moreover, differences in sandloss between the investigated tree species (deciduous, evergreen) revealed that the erosion potential and the spatial heterogeneity of throughfall are species-specific. This highlights the importance of selecting specific species for afforestation projects considering the prevention of soil erosion.Christian Geiβler Peter Kühn 史学正 Thomas Scholten 2010Journal of Earth Science2010,21,6:2
