波罗的海是世界上受人类活动影响最严重的海洋之一,虽然有减少向波罗的海排放营养物质的国际协议,但迄今为止采取的措施,既没有从根本上减少营养物质的排放,也没有促进环境的改善。部分原因可以归咎为缺少有关物理学、生物地球化学和生态特性之间大尺度关系和相互作用的知识,但是还缺少全流域范围的成本效益分析。错误的决策非常危险,例如,执行的减少排放的方案根本没有效果,或远远达不到成本效益。许多学科的研究者正面临着一个共同的挑战:开发一个决策支持系统,作为整个波罗的海成本效益分析法的科学基础。研究项目海洋富营养化的研究(MARE)(http://www.mare.su.se)正致力于这方面的研究。
The Baltic Sea, one of the most severely affected oceans in the world by human activity, although there are international agreements to reduce the discharge of nutrients to the Baltic Sea, the measures taken so far have neither radically reduced the emission of nutrients nor promoted the environment improve. Part of the reason can be attributed to the lack of knowledge about the large-scale relationships and interactions between physics, biogeochemistry and ecology, but also a lack of cost-benefit analysis across the river basin. Wrong decisions can be very dangerous. For example, a program to reduce emissions that is implemented has no or far-reaching cost-effectiveness. Researchers in many disciplines are facing a common challenge: to develop a decision support system that serves as the scientific basis for the cost-benefit analysis of the entire Baltic Sea. Research Project Marine Eutrophication (MARE) (http://www.mare.su.se) is working on research in this area.
