Research on fine Spatial Quantitative Model about vulnerability of hazard-affected bodies

Figures & data

Table 1. The index system of regional vulnerability of hazard-affected bodies.

Objective layer	Index layer (I i )/W i	Index factor
Evaluation of regional vulnerability of hazard-affected body	Land-use type/0.4	Residential area
		Town area
		Water area
		Dry land area
		Woodland area
		Grassplot area
		Paddy field area
	Social economy/0.3	Value of primary industry
		Value of secondary industry
		Value of tertiary industry
	Distribution of population/0.3	Density of population
