Study On The Outdoors Public Space And Space Utilization Of The Urban Commercial Complex

With the development of social economy and the expansion of city, the urbanization caused many problems including the lack of land and space resource. The urban commercial complex is the important organization of the high density city and city complex. The open and public space of urban commercial complex not only organize the function system of complex, but also content the complex and city. Nowadays, there are many problems to the urban commercial complex, including the problem to ignore the quality of public space system, and which does not provide the good space to people. Therefor, with the view of people who use the space, to research the urban commercial complex and civilization has not only theoretical significance but also practical value.Based on the urban complex theory and multiple linear regression analysis related, and in the case of GuangGuTianDi commercial complex of Wuhan, the paper research the urban commercial complex public space and the relationship between space utilization, which has three aspects. Firstly, paper studied the spatial organization and spatial elements of GuangGuTianDi, and summarized the public space characteristics of GuangGuTianDi. Secondly, paper researched the public utilization of GuangGuTianDi through the investigation. Finally, the paper studied the relationship between public space and utilization of GuangGuTianDi by using multiple linear regression analysis method. The study concluded that: the form and scale, path and environmental of public space factors on the public space utilization, the influence degree from high to low is: the number of path, space type, D/H, space number, space enclosure, brightness, green quality, turning point, the number of seats, area. Therefore, the design of public space of urban commercial complex should focus on accessibility and recognition of space. Then we should take into account the spatial form and spatial scales of the urban commercial complex. And different function space organization should also be considered in, rather than blindly arrange the green space environment.
