挪威多领域环保优先政策

为了达到挪威在国际协议中承诺的环保目标，政府的战略是制定一套综合环保政策。在此情况下，改善环境的措施需要在多个领域中实施。为此，每一个公共行政部门在制定所有的计划和发展规划时，有责任确保突出考虑环境问题。为了检查各个部门环保责任的完成，每个政府部门在年度预算中，都必须提出并量化其决定实施的环保措施。     

Controlled-release fertilizer(CRF):A green fertilizer for controlling non-point contamination in agriculture

Fertilizers contribute greatly to high yields but also result in environmental non-point contamination, including the emission of greenhouse gas(N2O) and eutrophication of water bodies. How to solve this problem has become a serious challenge, especially for China as its high ecological pressure. Controlled-release fertilizer(CRF) has been developed to minimize the contamination while keeping high yield and has become a green fertilizer for agriculture. Several CRFs made with special coating technology were used for testing the fertilizer effects in yield and environment through pot experiment and field trial. The result indicated that the CRFs had higher N use efficiency, thus reducing N loss through leaching and volatilization while keeping higher yields. Comparing with imported standard CRFs,the test on CRFs showed similar fertilizer effect but with much lower cost. CRFs application is becoming a new approach for minimizing non-point contamination in agriculture.     

促企业自律让百姓知情

近年来，我国接连发生重大环境事件，其严重后果给国家的生态环境安全和可持续发展的能力带来了前所未有的威胁。究其原因，除了部分企业负责人对自身生产安全的保障不力外，一部分企业和地方政府在环境信息公开方面的缺陷也是使污染事件影响范围扩大的另一个重要因素。因此，要想促企业自律，让百姓知情，环境信息公开就成为今后一段时间环保工作努力的方向之一。
