Abstract: With the random accumulation or landfill of construction waste in the process of urbanization, a large number of informal construction waste dumps appeared. Garbage Besieged City becomes a prominent problem of the current society in China. Therefore, it is urgent to study the present situation and countermeasures of spatial distribution of construction waste for the optimization of spatial distribution of construction waste in China. This paper took Changping District of Beijing as an example, identified the number, geographical location, area, distance from residential areas and rivers and other information of informal construction waste dump sites based on Google earth and GIS software, and then obtained the general information of garbage distribution. The spatial layout characteristics of these information in terms of point space, distribution and elevation were analyzed, so as to clarify the layout problem of informal garbage dump, and then the problems in irregular garbage dump layout was clarified, and suggestions were also put forward, so as to improve the management capacity of construction waste and solve the problem of Garbage Besieged City.
