Evidence-based decision making and policy development rely on the syntheses of available scientific knowledge and the identification of respective knowledge gaps. This article presents a participatory systematic map, which constitutes a relatively new methodological approach in the field of ecosystem services (ES) research. The map identifies, collates, and describes the evidence base on marine and coastal ES research in the Baltic Sea. Key stakeholders were involved throughout the whole mapping process. 1006 publications, identified through searches in eleven databases, were double-screened and 57 publications were found eligible. The results show that research on provisioning, regulating and cultural ES is uniformly distributed in the evidence base while most studies applied bio-physical assessment approaches. The most frequently researched ES are the regulation of nutrients, the provision of fish, and recreation. Only a few studies were conducted in the context of marine policies. While ES research is growing in the Baltic Sea area, this systematic map highlights the plethora of definitions and lack of standardized approaches as an obstacle for policy implementation. The method of participatory systematic mapping was identified as a useful tool for ES research to identify all available knowledge on a specific topic, determine knowledge gaps and inform both researchers and policy makers.

基于证据的决策和政策制定依靠现有科学知识的综合以及对相应知识差距的识别。本文介绍了一个参与性系统地图，它构成了生态系统服务（ES）研究领域中一种相对较新的方法论方法。该地图标识，整理和描述了基于波罗的海海洋和沿海ES研究的证据。关键利益相关者参与了整个制图过程。通过在11个数据库中搜索确定的1006种出版物进行了双重筛选，发现有57种出版物符合条件。结果表明，有关提供，规范和文化环境服务的研究均匀地分布在证据库中，而大多数研究则采用生物物理评估方法。研究最频繁的生态系统是营养的调节，鱼类的供应和娱乐。在海洋政策方面仅进行了少量研究。尽管波罗的海地区的ES研究在不断发展，但这份系统地图突显了太多的定义，而且缺乏标准化的方法，成为政策实施的障碍。参与式系统测绘方法被认为是ES研究的有用工具，可用于识别特定主题上的所有可用知识，确定知识差距并为研究人员和决策者提供信息。该系统地图突出了过多的定义，并且缺乏标准化的方法，这是政策实施的障碍。参与式系统测绘方法被认为是ES研究的有用工具，可用于识别特定主题上的所有可用知识，确定知识差距并为研究人员和决策者提供信息。该系统地图突出了过多的定义，并且缺乏标准化的方法，这是政策实施的障碍。参与式系统测绘方法被认为是ES研究的有用工具，可用于识别特定主题上的所有可用知识，确定知识差距并为研究人员和决策者提供信息。
