Abstract: Through field geological survey and comprehensive analysis, this paper investigated major geological factors which may influence urban engineering construction and their development characteristics. These factors include topography and geomorphology, hydrology, engineering geology, hydrogeology and geological hazard. Suitability for engineering construction was evaluated using multifactorial weighted index method. The study area can be divided into three suitable areas: well suitable, generally suitable and poorly suitable. The urban area in the city of Huangshan has favorable geo-environmental conditions, with the first two areas jointly distributed widely, and this is basically consistent with qualitative analysis results. The understanding above can provide basic information and decision-making basis for urban planning, construction, development and project location of the urban area of Huangshan.
