Abstract:The urban planning and public spaces renewal in Barcelona has become a model for the world. The course of urban parks renewal is also worth learning from.Considering the analysis of the background of Barcelona's urban renewal plan and policy,this paper analyzes the historical process of Barcelona’s urban park renewal,and divides it into three main development stages,namely,the embryonic period of focusing on bring nature into the city (1850s-1970s),the development period of seeking harmony between man and nature (1980s-1990s),and the mature period of considering the relationship between man, nature and city (early 21 century to present).Through field investigation and multi source data analysis,six characteristics of urban park renewal are summarized with related examples: policy guidance,humanistic care,dependence of transportation infrastructure,the integration of art and landscape,biodiversity and the green network,and climate change resilience.
