Abstract: The engineering site is far apart from city by spatial scale but the engineering site provides environmental behaviors of approximate common character. Its attributive analysis may be applied to the entire engineering geologic environment faced by urban construction. In this sense, engineering site is a microunit of the entire urban macro engineering geologic environment. The combination of many microunits constitutes the macro overall of environment. Hence, the three attributes of engineering site - property, suitability, stability, may be used as bases of analytic methods in the analyses of urban engineering geologic environment. Spreading engineering site analysis to urban engineering geologic environment analysis will be helpful to guarantee to quantitative level of urban engineering geologic environment analysis.
