Abstract: Barrier free facilities construction is an important part of urban construction, but also the spirit of the city and the degree of civilization of the show. By means of interviews and questionnaires, the main causes of the public and accessible facilities are obtained, based on the theory of public participation in urban construction. The results shows that with the requirement of urban construction and the promotion of social equity, and the arrival of the aging society, Lanzhou barrier free facilities continues to improve. The city government has carried on the barrier free transformation to the existing buildings, roads and so on and has made a clear division of responsibilities in the planning, design, construction, maintenance and other aspects of the barrier free facilities. But based on the public view, the attention and satisfaction of the overall evaluation is not high, especially the satisfaction evaluation of public buildings. Combining with the interview with the main users of the barrier free facilities, the results of this paper shows that there are various problems in the construction of barrier free facilities in Lanzhou City. These problems mainly include that planning and design coverage is not complete, construction is not reasonable, capital investment is short, the implementation of relevant policies and regulations and the implementation of the effect is not ideal, facilities maintenance is not timely. Urban development will promote the construction of urban barrier free facilities. But there are loopholes in the planning, design, construction, maintenance and management in the process of the construction of barrier free facilities. This leads to the construction of barrier free facilities lagging behind urban development. Therefore, we should pay attention to the construction of barrier free facilities and further strengthen public participation、regulatory system、fund management、planning、maintenance management to improve the level of the construction of barrier free facilities.
