摘　　要：夏季是作物生长发育的重要时期,而夏季极易发生干旱灾害,从而阻碍作物生长。因此利用2000~2019年黑龙江省降水资料、地理信息数据和社会经济数据,对黑龙江省夏季干旱灾害风险区划进行研究。结果表明:1) 致灾因子危险性较高的地区主要在黑龙江省西部,其他地区危险性较低。2) 孕灾环境敏感性表现出北部、西部、南部较高,中东部较低。3) 承灾体暴露性较高的地区主要分布在西南部、东北部较低。4) 防灾减灾能力较高的地区主要分布在东部、南部,防灾减灾能力较低的地区分布在西部。5) 综合风险性主要表现为由西向东逐渐减小的趋势,西部的龙江县、齐齐哈尔市、泰来县、杜蒙等地为主要高风险性区。Summer is an important period for crop birth in development, and summer is highly susceptible to drought disasters, which can hinder crop growth. Therefore, using precipitation information, geographic information data and socio-economic data from 2000~2019 in Heilongjiang Province, the risk zoning of summer drought disasters in Heilongjiang Province was studied. The results show: 1) the areas with higher risk of disaster-causing factors are mainly in the western part of Heilongjiang Province, and the other areas have lower risk. 2) The sensitivity of the disaster-inducing environment is higher in the north, west and south, and lower in the middle and east. 3) The areas with higher exposure of disaster-bearing bodies are mainly located in the southwest and lower in the northeast. 4) The areas with higher disaster prevention and mitigation capacity are mainly distributed in the east and south, and the areas with lower disaster prevention and mitigation capacity are distributed in the west. 5) The comprehensive riskiness mainly shows a trend of gradually decreasing from west to east, with Longjiang County, Qiqihar City, Tailai County and Dumeng in the west as the main high-riskiness areas.
