The Space-time Evolution Of Xian City Industrial Research And Industrial Layout Optimization

Since the reformation and opening,the economic system has changed from the planned economy to the market economy in china.The domestic cities conv erted gradually from production-based cities to consumer-oriented cities.New ch anges of urban industry have begun to appear, for instance,the leading role of industrial development has been transformed from manufacturing industry to hig h-tech industry and the industrial layout has become market-oriented.As the im portant industrial city in the northwest part of China,Xi’an should grasp every new opportunity of the industrial adjustment and develop the urban industry en ergetically so as to be on the road of new industrialization development.It is i mperative,combined with the theories about industrial layout,the characteristics o f urban industrial development at home and abroad,to find out the process of s patial and temporal evolution of urban industry,to sum up the laws of industria1layout,to propose some programmes for the optimization and adjustment of in dustrisal layout which can meet the requirement of Xi’an’s development.First of all,this articale provides an overview of the theories about urban i ndustrial layout. Secondly,it combs the progress of spatial and temporal evolutio n of Xi’an’s industry,combined with the progress of domestic and foreign theor etical research on urban industrial layout and the historical characteristics of th e urban industrial development.And then the articale analyses all the measures of optimization and adjustment for the urban industrial layout,with are presente d in the urban master plannings.At last,it summarizes the evolution laws;the pr esent characteristics and the existing problems of the industrial layout.Based onwhat has been described above,this articale analyses the influence factors and ensures it’s influence fower to the industrial layout of Xi’an City.furthermore,itprovides rational programmes and measures of optimization to the industrial la yout of Xi’an City in the future,which will achieve the ecoriomic development, the djustment of industrial structure and the sustainable development of Xi’an.
