With the development of economy and urbanization in China, citizens’ consumption demand has had a dramatic change. In order to meet citizens’ need, the commercial districts in the towns have been constantly constructed, reconstructed and enlarged. However, influenced by a series of factor like types of business, geographical environment and road systems, the planning and layout of commercial zones in the towns have these following problems: locations not fit for the long-term development of valley towns, disorder space layout, non-designed special structure nodes, inappropriate space scale, disorder and overlapping layout structure and waste of land resources.This thesis selected Tianshui, Dingxi, Gannan Tibetan Autonomous Prefecture, Hangzhong and representative towns in Longxi as survey sites. These sites are located at western parts of Qinling Mountains. The paper mainly conducted researches on land for commercial use, humanities and history in these areas and their spatial layout of business. It extensively collected first hand information about areas of land for commercial use, population, status quo of concentration of business, status quo of spatiality, citizens’ business behaviors and status quo of spatial environment. It discovered the facts that the scale of land for commercial use failed to cater the need of citizens, transit routes and commercial zones disturb each other, the idea of business layout structure is undeveloped and the spatial environments are ineffectively created.Combining relevant standards about planning and controlling in Standard for Planning of Town and Village, the thesis conducted researches on the basis of linear city theory, theory of combined effect of location, theory of consumer behavior and traditional idea about commercial streets.
