使用1992—2010年山东省东营市河口区气象站及区域自动站降水量资料、各乡镇人口和经济资料、地理信息以及灾情普查资料,分析河口区暴雨气候特征和灾害特征;在此基础上,基于GIS技术和百分位数、专家打分、层次分析、加权综合评价4种数据处理方法,计算各地暴雨洪涝风险系数,对该区暴雨洪涝灾害风险区划进行初步分析。结果表明,近19年,该区暴雨主要集中在夏季,最早出现在5月,最晚出现在9月,年暴雨频数最多达4次,日降水量≥50 mm的暴雨日数为33 d,最大日降水量为167.5 mm;该区暴雨洪涝风险西南高、东北低,其中西南部、南部以高风险区和次高风险区为主,北部、东部以低风险区和次低风险区为主;位于该区西南部的义和镇暴雨洪涝风险最大,新户镇和六合街道办事处次之,位于该区东部的仙河镇风险最小。

The precipitation data from 1992 to 2010 of Hekou meteorological station and its regional automatic weather stations,population and economy data from all the towns,geographic information and disaster census data have been employed to analyze the climatic and disaster characteristics of rainstorm in Hekou.In addition,tentative discussion on risk regionalization of rainstorm flood disaster in Hekou district is performed with the GIS technology and the four methods of data processing such as percentile method,expert scoring method,analytic hierarchy process（AHP）,weighted comprehensive evaluation and the risk coefficient of rainstorm flood.The results indicate that rainstorms in Hekou occur mainly in summer in the latest 19 years,and the earliest rainstorms is in May but the latest one in September.Annual rainstorm frequency is up to 4 times,and rainstorm days with over 50 mm daily precipitation is 33 days,the daily maximum precipitation is 167.5 mm.There is higher risk of rainstorm flood in the southwestern parts of Hekou and lower in the northeastern parts of Hekou,whereas those high and the secondary high risk zones primarily locate in the southern or southwestern parts of Hekou and low and the secondary low risk zone in the northern and eastern parts of Hekou.There is the greatest risk of rainstorm flood in Yihe town in the southwestern Hekou,and next to it is in Xinhu town and Liuhe sub-district offices,and the least one is in Xianhe town in the eastern part of Hekou.
