[ Objective] To reveal structure and function of alpine meadow ecosystem and thus to provide a scientific basis for development, utilization and scientific management of alpine meadow pasture as well as sustainable development of grassland agriculture. [ Method] Charactedstics of Kobresia humilis communities with primary vegetation （community I） and degraded vegetation （community II） were analyzed. [Result] Species richness, biodiversity index and biomass of the community I were respectively 42, 3. 531 and 3 553.1 g/m^2, which were respectively higher than those of the community II （37, 2.270 and 3 391.1 g/m^2）. Correlation analysis shows that community biomass was correlated positively with the dchness index （ P 〈 0.01 ）, and biodiversity index was correlated positively with the aboveground biomass and dchness index （ P 〈 0.01 ）. [ Conclusion] The Kobresia humilis community I has reasonable structure and large coverage of ground vegetation, which play an important role in maintenance of biodiversity and ecosystem function.

发展中国家尽管在科技上有了进步和发展，还面临一系列问题，如贫穷、饥饿、环境和自然资源恶化、城市化的负面影响及可再生能源，水和耕地管理，可持续农业、营养学、卫生和健康。为了解决所有这些问题，政府不得不依赖大学和其他教育机构的健康发展。它们是知识的创造者和传播者。关注知识的商品化成为一个日益强化的趋势。由此引出一个基础问题就是如何保持大学在知识的传播和维护区域价值和文化中的独特作用。本文讨论了大学外拓项目对区域发展及亚洲价值的现实意义。在追求发展、繁荣和幸福的道路上，应看到另一面。例如，2011年4月，一些政府和市民社会的几百位领袖齐聚联合国总部，探求一条新的道路，衡量一个国家是否公平。发展不应只作狭隘的经济考虑。发展应包括个人、社会和国家的身体、思想和灵魂的全部。文章还讨论了如何运用外拓的方式来引起学术上重新重视以不同的视角看待发展。有许多现代科学意义上的不同研究，也包括有助于思想、身体和灵魂整体发展的亚洲价值及实践的不同方面。本文认为大学的外拓和参与有利于将大学带入一种创业作用和文化作用的平衡。大学和学术界在改造社会中社会责任应主要集中于推行战略和概念。

The knowledge and understanding of African leafy vegetables has diminished over time, but in the recent past year there is more interest in their research for their nutritive and medicinal values. Of value are those that have the potential to ameliorate soil nutrient levels. This is with the background that despite inorganic fertilizers （IF） have a dramatic impact on agriculture in the world, the economic situation in Sub-Saharan African calls for alternative methods to reduce soil fertility degradation. The use of leguminous vegetables may be a solution. The study looks at the potential contribution of a leguminous traditional vegetable-- Crotalaria brevidens to soil nitrogen under various treatments. During the study which was conducted over two seasons, C. brevidens was grown under two treatments of IF and organic fertilizer （OF） with a control in which there was no fertilizer （NF） applied. A non-leguminous vegetable--Amaranthus dubious （Amaranth） was grown under the same treatments for comparison purposes. Soil analysis was done before and after planting in the treatment subplots. growth parameters were measured every fortnight and these included leaf number, shoot length, dry weight and nodule number for Crotalaria. Results indicated that the leguminous vegetable was not affected by external inputs and there were no significant differences between treatments and control. The non-leguminous vegetables responded well to both IF and OF treatments in all the measured parameters. This underlines the potential for improving soil nitrogen levels using leguminous vegetables, especially as intercrops with the non-leguminous types.
