人类面临的一个重要挑战是在为不断增长的人口提供资源的同时,减轻和适应持续的气候和生物多样性危机。生态集约化旨在最大限度地提高作物生产力,同时尽量减少对环境的影响,特别是通过利用生物多样性来改善生态系统功能和服务。许多生态集约化措施是基于生物营养级之间的相互作用(如授粉、生物防治)。在此,我们探讨了生物多样性对生态系统功能的多营养级效应的研究,如何能促进生态集约化措施在农业和林业中的应用。我们综述已有研究报道,并利用文献的定性分析来检验土地利用参数或栖息地复杂性等重要变量如何影响多营养级多样性、生态系统功能以及多营养级生物多样性与生态系统功能的关系。研究结果表明,生物多样性对生态系统功能的正效应在生产系统中普遍存在,主要跨越生态系统功能维度、营养级水平、研究方法和不同的生态系统功能,但存在一定程度的环境依赖性。土地利用和管理对多营养生物多样性和生态系统功能有显著影响。我们在代表性不足的地理区域、生产系统、生物类群和功能多样性测量数据方面发现了知识差距。此外,我们还确定了未来需要更多关注的几个方面,如多种功能之间的权衡、时间动态、气候变化的影响、措施的空间尺度及其实施。这些信息对于确保农业和森林景观在地球环境有限的情况下,持续地为人类生产资源至关重要。

Perceptions of Bark Beetle Landscape Disturbance Effects on Natural Resources and Drinking Water: Assessing Communication and Knowledge Exchange in the Rocky Mountain Region, UsA

引用

Open Journal of Ecology 2024年第1期14卷 77-100页

作者： stuart P.

Widespread changes to forested watersheds affected by the mountain pine beetle (Dendroctonus ponderosae Hopkins) epidemic across western North America raised concerns about the effects of this climate-induced disturbance on drinking water and natural resources. Effective communication and knowledge exchange across scientists and stakeholders (i.e., drinking water managers) is essential for constructively responding to such landscape scale disturbances, providing improved adaptive capacity through knowledge sharing. An assessment of stakeholder knowledge levels, information needs, primary concerns, and suggested communication strategies were conducted via an online elicitation survey and World science Café workshops. Knowledge levels, assessed via a survey of local water managers and experts, were relatively low with approximately half of the respondents reporting little to no knowledge of the effects of mountain pine beetle on drinking water quality and quantity, thereby indicating limited knowledge exchange between scientists and drinking water stakeholders. Increased accessibility and dissemination of research findings pertinent to the mountain pine beetle epidemic’s effects on drinking water quality and quantity is necessary for natural resource management. Recommendations for improved communication among scientists and drinking water stakeholders in particular and forest health in general include dispersal of non-academic research summaries, information exchange through existing media and community resources, demonstration projects, and information clearinghouses. This information provides a better understanding of the challenges, concerns, and first-hand experience of stakeholders of a landscape disturbance issue to apply this knowledge to enhance land management practice and how researchers on this overall project enhanced science communication efforts.

Numerical simulation of fluidized dense-phase pneumatic conveying of powders to develop improved model for solids friction factor

Particuology 2017年第6期15卷 42-50页

Accurate prediction of the solids friction factor through horizontal straight pipes is important for the reliable design of a pneumatic conveying system, but it is a challenging assignment to date because of the highly concentrated, turbulent, and complex nature of the gas-solids mixture. Power-station fly ash was transported through different pipeline configurations. Numerical simulation of the dense-phase pneumatic conveying systems for three different solids and two different air flow rates have shown that particle and actual gas velocities and the ratio of the two velocities increases in the flow direction, whereas the reverse trend was found to occur for the solids volumetric concentration. To develop a solids friction-factor model suitable for dense-phase flow, we modified an existing pure dilute-phase model by incorporating sub-models for particle and actual gas velocities and impact and solids friction factor. The solids friction-factor model was validated by using it for scale-up predictions for total pipeline pressure drops in longer and larger pipes and by comparing experimental and predicted pneumatic conveying characteristics for different solids flow rates. The accuracy of the prediction was compared with a recently developed two-layer-based model. We discussed the effect of incorporating the particle and actual gas velocity terms in the solids friction-factor model instead of superficial air velocity.

From Humanized Nature to Naturalized Humans-Li Zehou＇s Transformation of the Classical Chinese “Tianren Heyi” Paradigm Through the Lens of Kant and Eady Marx

引用

Frontiers of Philosophy in China 2018年第1期13卷 72-90页

作者： jana s. Rosker Department of Asian studies Faculty of Humanities University of Ljubljana Ljubljana 1260 Slovenia

Li Zehou belongs among the ranks of the most important Chinese philosophers of the 20th and 21st centuries. In his complex theoretical system, he aimed to reconcile the Chinese cultural heritage with the demands of the contemporary world. Besides elaborating on traditional Chinese philosophy, Li launched many innovative views based on his understanding of specific developments in pre-modern and modern Western philosophy. His philosophy could be described as the search for a synthesis between Western and traditional Chinese thought and a specifically Chinese modernization. In order to provide a basic insight into Li＇s specific methods of combining Kant, early Marx and classical Chinese philosophy, the present article investigates his elaboration of the traditional Chinese paradigm of “the unity of nature and man” （tianren heyi 天人合一） through the lens of ideas about humanized nature （renhua de ziran ）人化的自然） and naturalized humans （ziranhua de ten 自然化的人）.

Entropy analysis of unsteady magneto-nanofluid flow past accelerating stretching sheet with convective boundary condition

引用

Applied Mathematics and Mechanics(English Edition) 2015年第12期36卷 1593-1610页

作者： s.DAs s.CHAKRABORTY R.N.jana O.D.MAKINDE Department of Mathematics University of Gour Banga Department of Applied Mathematics Vidyasagar University Faculty of Military science Stellenbosch University

The unsteady laminar magnetohydrodynamics （MHD） boundary layer flow and heat transfer of nanofluids over an accelerating convectively heated stretching sheet are numerically studied in the presence of a transverse magnetic field with heat source/sink The unsteady governing equations are solved by a shooting method with the Runge-Kutta- Fehlberg scheme. Three different types of water based nanofluids, containing copper, aluminium oxide, and titanium dioxide, are taken into consideration. The effects of the pertinent parameters on the fluid velocity, the temperature, the entropy generation num- ber, the Bejan number, the shear stress, and the heat transfer rate at the sheet surface are graphically and quantitatively discussed in detail. A comparison of the entropy generation due to the heat transfer and the fluid friction is made with the help of the Bejan number. It is observed that the presence of the metallic nanoparticles creates more entropy in the nanofluid flow than in the regular fluid flow.
