Abstract

Abstract: In order to quantitatively assess the geological disaster risk, with the help of GIS software, Shaoxing city is divided into grids, and the evaluation index system and index evaluation model of geological disaster risk are constructed in this paper. Through the quantitative evaluation of geological disasters in Shaoxing city, the vulnerability degree of geological disasters in Shaoxing city is finally divided into four grades:high, medium, low and not easy, and the zoning achievement map of the vulnerability of geological disasters in Shaoxing city is drawn. The research results support the "14th five-year plan" of Shaoxing city geological disaster prevention and control, and serve Shaoxing city geological disaster prevention and control management and decision-making.

Key words: geological disaster, prone zone, urban planning, risk index evaluation model
