三峡水利工程建设三对峡地区环境影响与控制对策

本文对三峡工程开工以来对三峡地区的环境影响作了综合评价，揭示了受工程影响后所产生的大气环境、水环境、生态环境等问题。然后针对出现的若干问题，论述了大型水利工程对环境大系统影响的模糊性，提出了环境影响“不确定性”的概念，同时试图应用可靠性分析方法来评价各种不确定性的环境因素。针对三峡工程建设所产生的实际环境问题，提出了控制与治理对策。     

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.
