摘要
论文以赣州市为例,对自然灾害的时空分布特征进行了研究。利用2011年-2020年年度自然灾害综合风险普查的灾情数据,结合统计部门发布的社会经济统计数据,通过构建灾情指数模型,对赣州市自然灾害损失和时空分布情况进行了分析和聚类。结果表明,赣州市是全国遭受自然灾害较为严重的设区市之一;洪涝、风雹、台风和干旱灾害是影响赣州市最为严重的灾害类型;受地理条件和经济发展水平的影响,赣州市自然灾害灾情总体上呈现四周重、中部轻的空间分布格局。论文结合赣州市土地利用数据,对赣州市灾情信息进行了空间聚类分析,并对防灾减灾工作提出了相应建议。
This paper takes Ganzhou as an example to study the spatial-temporal characteristics of natural disasters.Using the annual disaster data of Ganzhou city from 2011 to 2020 in the comprehensive risk survey of natural disasters,combined with the social and economic statistical data released by the statistical department,a disaster index model is constructed to analyze and cluster the loss and spatial-temporal distribution of natural disasters.The results show that Ganzhou city has been severely affected by natural disasters,and among which floods,hail,typhoons,and droughts are the most serious.Influenced by geographical conditions and economic development,the natural disasters in Ganzhou city are generally serious in the periphery and light in the central area.Based on the land use data of Ganzhou city,spatial clustering analysis is conducted on the disaster information,and suggestions are putforward fordisasterprevention and reduction.
