Base On Composite Ecological Ideal Research For The Locality Feature Of Urban Street Space Design

Regional is one of important factors of urban street space design, but in nowadays, speeding economic globalization and urbanization comes with blind self-construction and disorder in city, many urban street space designs are going into convergence while loosing regional characteristics, there are many reasons behind it, from design point of view, the root cause is the "Identity Crisis" led by blind imitation of developed countries, which has caused severely damage in urban regional ecosystem in our country, thus it is very important to research and utilize the method of regional characteristic on urban street space design under ecological concept.This study analyzed problems of construction in the city streets, and cause of regional characteristics loss.The indifference of the local environment and subjective reconstruction on geographical features are direct cause of lacking regional characteristics in the city. Which further demonstrates the regional is focus of shaping the city as well as internal motivation of urban sustainability.Article of this study introduces idea of complex ecosystem and ecological niche to the research on regional characteristics of street space, through analysis of 3 major ecosystems under Complex ecological concept-ecological niche, niche economic, social and ecological niche, associations between those internal sub-systems and regional characteristics is concluded and demonstrated. Based on analysis of representative case study from national and international, the article raised overall idea and frame for street space design, and criteria of building regional characterized street space under complex ecological concept, and recommended to validate in specific design practice.
