陕西省自然灾害脆弱性研究

利用2009-2015年陕西省自然灾害灾情数据，结合数理统计分析方法，对该区域自然灾害进行时空特征分析，并对其灾害脆弱性进行研究。结果表明， 受灾人口、农作物受灾面积是研究区域自然灾害脆弱性的直接表现形式，灾害造成的直接经济损失是自然灾害脆弱性的间接表现形式。陕西省自然灾害脆弱性具有明显的时空分布差异性，自然灾害脆弱性较高的地区主要分布在东部，而中部的西安、铜川市是自然灾害脆弱性较低地区。该研究为防灾减灾、预报预警部门提供了决策依据。

Research on the vulnerability of natural disasters in Shaanxi Province

Based on the data of natural disasters of Shaanxi Province from 2009 to 2015, this paper analyzed the spatial and temporal characteristics of natural disasters in this area and evaluated their vulnerability with the combination of mathematical statistical analysis. The results show that the affected population and the affected area of crops are the direct manifestation of the vulnerability of natural disasters. The direct economic loss caused by disasters is the indirect manifestation of the vulnerability of natural disasters. The vulnerability of natural disasters in Shaanxi Province has obvious spatial and temporal distribution differences. The areas with high vulnerability to natural disasters are mainly distributed in the eastern region, while Xi'an and Tongchuan city in the midland are low vulnerability areas. The research provides the decision making basis for the department of disaster prevention and prediction.
