在本文中，地下公共空间质量评估方法被通过对场地中的影响地下空间设计质量

In this paper, the underground public space quality assessment method is proposed from the four levels of exterior connection, space safety, interior environment, and Operation by analyzing the influencing factors in the site that affect the design quality of underground space. <br>In terms of exterior connection, the external extension of the underground public space should highlight the recognizability; the underground public space also has the attributes of the above-ground public space, so the accessibility is one of the elements that activate the underground public space; the transportation facilities of the underground public space should be mutually Connected to reduce the problems caused by traffic flow; more activities should be integrated into the underground public space to reflect the public attribute function of the space.

In this paper, the underground public space quality assessment method is proposed from the four levels of connection, space safety, interior, environment and Operation by analyzing the factors affecting the quality of underground space design in the site.<br>In the aspect of the outer connection, the external extension of underground public space should highlight the recognizability; Underground public space also has the properties of above-ground public space, so accessibility is one of the elements that activate underground public space. The transportation facilities of underground public space should be interconnected to reduce the problem of traffic inflow, and more activities should be integrated into the public attribute function of the space.

In this paper, the quality assessment method of underground public space is proposed from four aspects, namely, exterior connection, space safety, interior environment, and operation, by analyzing the influencing factors in the site that affect the design quality of underground space.<br>In the aspect of exterior connection, the exterior extension of the underground public space should be highly recognizable; the underground public space has the attributes of the above ground public space at the same time, so accessibility is one of the elements to activate the underground public space; The traffic facilities of the underground public space should be connected to each other to reduce the problems caused by the unsmooth traffic; more activities should be integrated into the underground public space to reflect the public attribute function of the space.<br>
