- 摘要:
- 评价社会脆弱性对于分析自然灾害对人类经济社会的潜在风险具有重要意义。从人口、经济、基础设施脆弱性和防灾减灾能力四个方面选取了12个评价指标，并运用专家调查法结合层次分析法确定指标权重，建立数学评价模型，对河南省县域单元自然灾害社会脆弱性进行综合分析。结果表明：河南省东部地区自然灾害人口脆弱性和经济脆弱性普遍高于西部地区，基础设施脆弱性较高的地区则主要分布于西北部；防灾减灾能力西北部整体较高，东部和南部较低，各地级市辖区防灾减灾能力明显高于一般县域；自然灾害社会脆弱性大致上呈现以“东北—西南”一线较高，两侧县域社会脆弱性等级较低的空间分布格局。研究结果可为河南省进行自然灾害风险管理和防灾减灾规划提供科学依据。
- Abstract:
- Social vulnerability evaluation is of important significance for analyzing risks of natural disasters to human society and economy. By using expert investigation and AHP method, twelve indicators from four aspects including population, economy, infrastructure and disaster prevention and mitigation capacity were selected to assess social vulnerability to natural disasters on county scale in He’nan Province. The results showed that the population vulnerability and economy vulnerability to natural disasters in eastern He’nan Province were generally higher than in the western region, while higher infrastructure vulnerability mainly located in the northwest. The disaster prevention and mitigation capacity in northwest was higher than in east and south of province, and the county town was lower than urban area. In terms of the spatial pattern, social vulnerability to natural disasters was roughly higher in the belt from northeast to southwest, and lower on both sides of the belt. The results can provide scientific basis for disaster risk management and planning strategy of disaster prevention and mitigation in He’nan Province.
