It is found tha t vacant ratio of samples in Guangzhou accounted for 20.94%, which is relativel y high. The authors argue that real estate industry of Guangzhou has made rapid progress, at the same time, people should not overlook the vacant commercial hou sing. It will benefit the sustainable development of the real estate industry of Guangzhou to carry out effective measures and actively to make use of present v acant housing.展开更多

This paper totes to carry out some methods, such as muhi.analysis statistics method, to specify the impacts of urban land use on urban transport system. Firstly, the choice of urban transport road network affected by the characters of urban land use layout is discussed Secondly, the promotion of urban public transportation affected by high-density concentrated land use pattern is demonstrated Thirdly, the impacts of urban city-size on transport system structure characters are expatiated Finally, the impacts of urban mater planning in Guangzhou on the layout of transport system are illustrated .展开更多
