| 摘 要： | 根据杭州市1959-2010年降水资料、自然环境以及社会经济要素，综合致灾因子、孕灾环境、承灾环境及防灾减灾能力，构建区域干旱灾害风险评价模型。通过ArcGIS空间分析技术结合模糊综合评价法，编制以100 m＆#215;100 m栅格为基本评价单元的杭州市伏、秋旱灾害风险区划图。区划结果表明，淳安西北部、建德中南部、桐庐中部、富阳南部、临安东部以及余杭、主城区，伏旱、秋旱灾害风险均较高。

| Abstract: | Based on the 1959-2010 pr ecipitation data combined with the natural environment and the society economic factors of Hangzhou city, a regional drought risk disaster assessment model including disaster environment factor, disaster prevention and mitigation disaster capacity, was built up to analyze disaster prevention ability. By using the ArcGIS spatial analysis technology, combined with fuzzy comprehensive evaluation method, the autumn drought disaster risk zoning based on the 100 m ＆#215;100 m evaluation grid as the basic unit of Hangzhou city was established. The results show that, in the northwest of Chun＆#39;an, central and southern Jiande, central Tonglu, southern Fuyang, eastern Lin＆#39;an and Yuhang and the main urban areas, summer and autumn drought disaster presented higher risk. |
