Collapse, landslide and debris flow are common geological hazards in Guangdong, China. To understand the temporal and spatial changes of the risk of collapse, landslide and debris flow in the province and their driving factors are of great significance for the regional development and hazard prevention and reduction. As it is difficult to obtain the value of land resources directly, in this paper, based on existed evaluation model on debris flow hazard’s vulnerability, land resource value is estimated indirectly by using the regression equation between land value and the output values of farming, forestry, animal husbandry, side-line production and fishery, and related industries. Thus the problem of quantitative evaluation of vulnerability can be solved. Temporal and spatial variations of collapse, landslide and debris flow risk in Guangdong during the 10 years from 2000 to 2010 are analysed comparatively. The results show that in 2010, the average risk of collapse, landslide and debris flow in Guangdong was 0.366, and the areal weighted average risk was 0.363, increasing by 0.017 and 0.014, respectively, as compared with those in 2000. In 2010, the number of the counties with high risk was 43, increased by 10 as compared with that in 2000. In 2010, the area with high risk was 89 262 km2, which was 24 301 km2 more than that in 2000. The high risk area mainly increased in the Pearl River Delta region, and expanded to coastal area. The economic and social development of Guangdong has significantly increased, which also causes an increase of the risk of collapse, landslide and debris flow, as well as the changes of the temporal and spatial patterns of the risk. The change of the economic and social conditions is the main driving factor for the temporal and spatial variations of collapse, landslide and debris flow risk in the province.
