摘　　要：文章以“减少灾害风险”为目标,从全球变化、区域压力、当地社会生态条件等方面构建县级国土空间总体规划中灾害风险评估的概念框架;借鉴欧洲国家半定量风险评估方法,设计简明易操作的评估流程,并应用于新疆克孜勒苏柯尔克孜自治州阿合奇县的研究,有三点发现:(1)空间相关性是确定灾害风险评估范畴的关键;(2)生态极重要区由于其人口低暴露,在空间上与高灾害风险区表现出异质性;(3)城镇建设适宜区和农业生产适宜区存在高灾害风险。Taking'disaster risk reduction'as the goal,this paper constructs the conceptual framework of disaster risk assessment from the aspects of global change,regional pressure and local social and ecological conditions.Based on the semi-quantitative risk assessment methods of European countries,a concise and easyoperated assessment process was created and applied to Aheqi County.There are three findings:(1)Spatial correlation is the key to determine the scope of disaster risk assessment.(2)Ecologically extreme important areas show spatial heterogeneity with high-hazard risk areas due to their low population exposure.(3)Urban construction appropriate areas and agricultural production appropriate areas have high disaster risk.
