| Abstract: | Considering geological hazards as a sensitive factor in comprehensive evalua-tion of city engineering geological environmental quality, this paper puts for-ward a concept of the contribution degree of geological hazard in the research of the site of Fengjie city in Sanxia reservoir area. By means of researches on the environmental engineering geology of the city with the systematic theory and its analysis method, adoption of the-systematic "series-parallel connection" evaluation method of comprehensive judgment, quantitative comprehensive evaluation and divi-sion of the area of engineering geological environment for the new site, it has been proved that the evaluation result is good through the examination of random sampling. |
