1放牧对内蒙古大针茅草原土壤剪切力空间分布的影响显示文摘本研究在内蒙古草原生态系统研究站的持续放牧(CG)和禁牧(UG79,从1979年开始禁牧)两个试验区。利用GPS在每个区分别设立1个长135m×105m的样地,每样地选100个测量点,利用Hand-held vane tester测量土壤剪切力并研究其空间分布情况。结果表明,CG区,放牧导致土壤孔隙减少,容重增加,有机质减少,土壤剪切力高于凋落物与有机质较多的禁牧小区。在UG79和CG两个区,从干旱条件到中等水分条件,土壤剪切力空间分布都有差异,说明土壤含水量在一定程度上决定了土壤剪切力的空间分布,但到达湿润条件后,其分布有恢复原状的趋势,这暗示土壤水分对其影响也存在限制。甘磊 彭新华 谢永雄 钟家尚 Stephan PETH Rainer HORM 2014草业科学2014,31,2:3

9柏林EDGE Suedkreuz办公综合体显示文摘项目是一座七层高的办公大楼,由两栋建筑组成,总建筑面积约为32000平方米,占地约10100平方米,采用可持续和资源节约以及模块化混合木材建筑技术建造。两座独立建筑中较大的一座占地面积约为20000平方米,这使得它在未来一段时间内将成为德国最大的独立式混合木结构建筑,也是欧洲最大的建筑之一。作为能源供应商Vattenfall的新德国总部,新办公大楼也是新城区的一部分。Sergei Tchoban Stephan Lohre Karsten Waldschmidt Julia Angelstorf Lev Chestakov Giorgia Fontana UIrike Graefenhain RenéHoch Anastasia Kapustina Valeria Kashirina Birgit Koeder Achim Linde Fabiana Pedretti Dennis Petricic Manuela Peth Soeren van Ost Fabio Prada Anja Schroth Katharina Stranz Carolin Trahorsch 舒禹(编译) 2023现代装饰2023,,2:0
10Investigation of time dependent development of soil structure and formation of macropore networks as affected by various precrop species显示文摘A well developed macropore network is advantageous in terms of transport processes regarding gas and water,as well as nutrient acquisition and root growth of crops.X-ray computed tomography provides a non-destructive method to visualize and quantify three-dimensional pore networks.Geometrical and morphological parameters of the complex pore system such as connectivity,tortuosity,porosity and pore surface area would be very useful for modeling and simulation of transport and exchange processes by providing quantitative data on relevant soil structural features and their modification by soil management.The scope of this study was to analyze and quantify the development of soil structure in the subsoil depending on three different precrop species(alfalfa A,chicory C and fescue F),at three depths(45,60 and 75 cm)and cultivation periods(1,2 and 3 years).Furthermore,morphological(air-filled porosityθa,pore surface area)and geometrical(pore diameter,connectivity,continuity,tortuosityτ)parameters were gathered with X-ray CT and image analysis.From an experimental field trial(Germany)with a Haplic Luvisol as soil type samples were taken and investigated.Air-capacity(θa)was measured in the laboratory for the same cylinders and compared to the results derived by image analysis.Air-capacity was highest for alfalfa(3 years,75 cm).Tortuosity(τ)ranged between 1.3 and 4.38,while alfalfa(3 years)showed the highest value,which indicated structural development due to crack formation by enhanced root water uptake.Thus,an increase in accessible surface may improve water and nutrient supply for plants,whereas the highτvalues may assume that oxygen supply is limited.It was found that the interaction of gas-diffusivity and the calculated parameters should be further investigated in terms of limitations to plant growth.Sebastian K.Pagenkemper Daniel Uteau Puschmann Stephan Peth Rainer Horn 2014International Soil and Water Conservation Research2014,2,2:0
