| 为明确阿克苏地区干旱灾害风险及其区划，利用层次分析法和加权综合评价法，基于SPAC（soil\|plant\|atmosphere continuum）系统，从致灾因子危险性、孕灾环境脆弱性、承载体暴露性三个方面构建农业干旱灾害风险评价指标体系。整合多源数据信息，将阿克苏地区划分为5个干旱灾害风险等级。结果表明：阿克苏地区农业干旱灾害风险高，中等风险及以上的区域占阿克苏地区总面积的78.1%，且呈“南高北低”的特征。高风险区主要分布在阿瓦提县、沙雅县和温宿县的南部；中高风险区主要分布在新和县西部、拜城县东部、库车市中部、柯坪县南部和阿克苏市南部；中风险区主要分布在库车市西南部和阿瓦提县北部。阿克苏地区绿洲农业干旱灾害风险不高，中低风险区和中风险区占绿洲总面积的68.6%，绿洲地区干旱灾害风险低于阿克苏其他区域，但温宿县绿洲区域干旱灾害风险高。 |

| To clarify the drought disaster risk and its zoning in Aksu region, the analytic hierarchy process and weighted comprehensive evaluation method were used, based on the SPAC (soil\|plant\|atmosphere continuum) system. An agricultural drought disaster risk assessment index system had been built based on risk of disaster factors, vulnerability of disaster\|producing environment, and exposure of carriers to scientifically assess the risk of agricultural drought disaster in the Aksu region. By integrating multisource data information, Aksu region was divided into five drought disaster risk levels. The results indicated: Aksu region faced a high risk of agricultural drought disaster,with 78.1% of the total area falling under the category of medium risk or above.The region was characterized by a high risk in the south and a low risk in the north. The areas with the highest risk were primarily located in the southern regions of Awati, Shaya,and Wensu Counties.The areas with medium\|high risk were mainly located in the western part of Xinhe County, the eastern part of Baicheng County,the central part of Kuqa City, the southern part of Koping County, and the southern part of Aksu City. The areas with medium risk were primarily located in the southwestern part of Kuqa City and the northern part of Awati County. The risk of agricultural drought disaster in the Aksu oasis region was not high.The medium\|low risk area and medium risk area account for 68.6% of the total oasis area. Additionally, the risk of drought disaster in the oasis region was lower than that in other regions of Aksu.However,the risk of drought disaster in the Wensu County oasis region was high. |
