Grey Relational Analysis of Geological Hazards and Urbanization Construction in China

Abstract

Urbanization is an important symbol of Chinese economic development and important measure and means for Chinese future strategic adjustment. However, the geological hazards seriously impede the development of urbanization; especially restrict the construction of urbanization. According to statistics, the total number of geological hazards in China between 2005 and 2016 were 286,267 times, resulted about 162,869 million yuanin economic consumption. In this paper, the correlation between urbanization construction and geological hazards is analyzed by means of grey relational analysis. The conclusions are as follows:The influence of ground collapses, debris flows and landslides on urbanization construction is the most enormous; the influence of ground settlements, ground fissures and collapses on urbanization construction is relatively small. So in the process of urbanization construction, it is important to prevent and control the ground collapses, debris flows and landslides, and also cannot ignore the impact of ground settlements, ground fissures and collapses.
