Abstract: In urban planning and construction, open spaces restoration are mostly limited to the urban existing land-use. In his book "Ecocity Berkeley: Building Cities for a Healthy Future", Richard Register put forward some bold ideas and beneficial suggestions in the ecological city strategy for Berkeley. This paper studied and analysis in-depth on this strategic concept, and summarized five enlightenments given in the urban open space construction and restoration, included are understanding the urban nature history, paying attention to the importance of biodiversity value, recognizing the long-term of natural recovery, construction of the natural system integrity, and consideration of the urban lands transformation.

摘要： 在当今城市规划建设中，开放空间建设与恢复大都囿于城市现状，瑞杰斯特在《生态城市伯克利：为一个健康的未来建设城市》一书中通过“为伯克利制定一个生态城市战略”提出了一些颇为大胆的设想与有益的建议。对该战略构想进行了深入的研读与解析，并总结了其在城市开放空间建设与恢复方面所给予的5点启示：了解城市自然史，重视生物多样性价值，认识到自然恢复的长期性，构建自然系统的完整性，考虑建设用地的系统撤回。
