在日本琵琶湖地区的重要城市群开展了一项创新的基于生态系统服务的可持续性评估，涵盖时间为1950年至2014年。根据琵琶湖及其水道的主要生态系统服务建立了一个22项指标的系统，即，水产品和水供应服务;洪水和水质调节服务;娱乐和旅游、科学研究和环境教育方面的文化服务;以及生物多样性方面的支持服务。首先，讨论了八种生态系统服务的变化，以及从发展轨迹中可以汲取的大量经验和困难教训。然后，根据可持续发展原则对指标进行重新排列，对区域过去60多年的可持续发展能力进行了评估。总的来说，这个城市群在可持续性方面一直在进步，尽管过去经济和社会发展是以环境恶化为代价的，而目前的经济衰退正在损害平衡发展和综合效益。结果直接导致区域发展的建议，特别是在经济复兴方面，从改善琵琶湖水资源管理的角度来看。此外，相关知识对世界上面临类似发展问题的其他地方具有教育意义和启发性。例如，为防止环境退化而采取的有效、甚至是开创性的对策，以及多方利益攸关者的参与和合作，可以作为一种有益的模式。此外，该研究报告还请人们进一步了解生态系统易受人为破坏的脆弱性，并强调在全面城市规划和可持续城市发展的背景下，预防措施优先于对策。(C)2017 Elsevier B.

An innovative ecosystem services-based sustainability assessment was conducted in the important urban agglomeration of the Lake Biwa region, Japan, covering the time period from 1950 to 2014. A 22-indicator system was established that was based on the major ecosystem services of Lake Biwa and its water courses, i.e., provisioning services regarding aquatic products and water; regulating services regarding floods and water quality; cultural services regarding recreation and tourism, scientific research, and environmental education; and supporting services regarding biodiversity. First, changes in the eight ecosystem services were discussed together with the considerable experience and difficult lessons that can be drawn from the development trajectory. Next, with the indicators rearranged according to sustainability principles, the regional sustainability over the past six plus decades was assessed. In general, this urban agglomeration has been progressing in terms of its sustainability, although economic and social development was achieved at the cost of environmental degradation in the past, and the current economic downturn is hurting the balanced development and integrated benefits. The results lead directly to recommendations for regional development, especially in terms of economic rejuvenation, from the perspective of improving management of Lake Biwa's water resources. Moreover, the relevant knowledge is educational and inspirational for other places in the world that are facing similar development issues. For example, the effective and even pioneering countermeasures that have been taken against environmental degradation, as well as the participation and collaboration of multiple stakeholders, could be useful as a model. Moreover, the study invites increased understanding of ecosystem vulnerability to anthropogenic devastation and emphasizes the priority of precautionary measures over countermeasures in the context of holistic urban planning and sustainable urban development.
