| 1 | Global assessment of nitrogen fertilizer:The SCOPE/IGBP Nitrogen Fertilizer Rapid Assessment Project显示文摘Nitrogen (N) availability is a key role in food and fiber production. Providing plant-available N through synthetic fertilizer in the 20th and early 21st century has been a major contributor to the increased production required to feed and clothe the growing human population.To continue to meet the global demands and to minimize environmental problems, significant improvements are needed in the efficiency with which fertilizer N is utilized within production systems. There are still major uncertainties regarding the fate of fertilizer N added to agricultural soils and the potential for reducing losses to the environment. Enhancing the technical and economic efficiency of fertilizer N is seen to promote a favorable situation for both agricultural production and the environment, and this has provided much of the impetus for a new N fertilizer project.To address this important issue, a rapid assessment project on N fertilizer (NFRAP) was conducted by SCOPE (the Scientific Committee on Problems of the Environment) during late 2003 and early 2004. This was the first formal project of the International Nitrogen Initiative (INI). As part of this assessment, a successful international workshop was held in Kampala, Uganda on 12 -16 January, 2004. This workshop brought together scientists from around the world to assess the fate of synthetic fertilizer N in the context of overall N inputs to agricultural systems, with a view to enhancing the efficiency of N use and reducing negative impacts on the environment.Regionalization of the assessment highlighted the problems of too little N for crop production to meet the nutrient requirements of sub-Saharan Africa and the oversupply of N in the major rice-growing areas of China. The results of the assessment are presented in a book (SCOPE 65)which is now available to provide a basis for further discussions on N fertilizer. | Arvin R.Mosier J.Keith Syers John R.Freney | 2005 | Science China(Life Sciences)2005，48，z2： | 3 |

| 5 | 半干旱、半湿润热带地区土地的可持续管理显示文摘土地的可持续经营管理不但充分保证了当前的生产力水平,同时也可在时间序列上保护土地资源基础而不会对子孙后代的生存、发展造成危害。从全球角度,这一点对半干旱、半湿润的广大热带地区尤为重要。本文提供了5个研究案例,包括非洲、拉丁美洲和亚洲不同的土地管理系统。本文首先概括了引起土地退化的生物物理原因和社会经济原因,继而讨论了这两者之间的联系,并概括它们在区域上的共性和差异。提出了克服土地退化的实际方法与建议,包括:评估土地退化程度和土地的可持续性、土地质量变化的指示因子、生物物理与社会经济的信息联系以及必要的研究机构与设立基金机制。同时也推荐了直接包含土地使用者在内的多学科性的和参与性的方法。 | Keith Syers John Lingard Christian Pieri Exequiel Ezcurra Guy Faure 王明亮 宋明军 | 1996 | 人类环境杂志1996，25，8： | 2 |
