西藏食物保障的自然资源相对优势分析

对西藏食物保障的自然资源相对优势研究表明 ,光能、生物、旅游资源是西藏食物保障的突出相对优势。这些资源具有独特、再生和易于持续开发利用等突出特点 ;水利资源和矿产资源具有明显的开发利用优势 ,但是 ,与经济落后形成了极大的反差 ,目前开发乏力 ,开发利用将带来后续管理与环境保护的沉重负担 ;耕地、草地与森林资源既具有明显的优势 ,又有突出的劣势 ,主要表现为数量的优势与质量的劣势。西藏未来食物保障 ,取决于如何将这些资源的相对优势有效组合、综合管理和合理开发利用。

Life cycle analysis and choice of natural gas-based automotive alternative fuels in Chongqing Municipality,China

Road transport produces significant amounts of emissions by using crude oil as the primary energy source. A reduction of emissions can be achieved by implementing alternative fuel chains. The objective of this study is to carry out an economic, environmental and energy (EEE) life cycle study on natural gas-based automotive fuels with conventional gasoline in an abundant region of China. A set of indices of four fuels/vehicle systems on the basis of life cycle are assessed in terms of impact of EEE, in which natural gas produces compressed natural gas (CNG), methanol, dimethylether (DME) and Fischer Tropsch diesel (FTD). The study included fuel production, vehicle production, vehicle operation, infrastructure and vehicle end of life as a system for each fuel/vehicle system. A generic gasoline fueled car is used as a baseline. Data have been reviewed and modified based on the best knowledge available to Chongqing local sources. Results indicated that when we could not change electric and hydrogen fuel cell vehicles into commercial vehicles on a large scale, direct use of CNG in a dedicated or bi-fuel vehicle is an economical choice for the region which is most energy efficient and more environmental friendly. The study can be used to support decisions on how natural gas resources can best be utilized as a fuel/energy resource for automobiles, and what issues need to be resolved in Chongqing. The models and approaches for this study can be applied to other regions of China as long as all the assumptions are well defined and modified to find a substitute automotive energy source and establish an energy policy in a specific region.

自然条件下石羊河终闾湖泊模拟研究

石羊河流域史前曾存在大面积的终闾湖泊---猪野泽。自西汉开拓河西以后的两千多年以来,受人类活动影响,石羊河流域土地覆盖发生了显著的变化。灌溉农田取代了天然绿洲,而且面积逐步扩大,农业用水急剧增加,猪野泽逐渐退缩成许多小湖,并于近代干涸。在假设人类活动（主要是灌溉）对水资源未加利用的条件下（理想状态）,通过确定流域的水量收支和改进水量平衡模型,对石羊河流域现代自然条件下“终闾湖”的面积进行了模拟重建,得出现代终闾湖的面积至少应为５８０ｋｍ^２。     

Service transformation—managing a shift from business travel to virtual meetings

It has been shown that the potential for environmental, and financial improvements through the increased substitution of in-person meetings by virtual communication is considerable. However, it has also been shown that this potential is not automatically realized by investing in the technology that can enable virtual meetings. This paper describes two case studies that explored the factors that influenced communication and meeting behavior. A number of drivers and barriers for virtual meetings are identified, and, in addition, measures are proposed to improve the utilization of virtual tools for business communication.
