潍坊市暴雨洪涝灾害风险区划

Risk zoning of flood and waterlogging in Weifang

利用潍坊市气象数据以及统计年鉴资料、基础地理信息数据、土地利用类型数据和历史灾情数据,基于暴雨洪涝灾害风险评估模型,结合GIS技术,对潍坊市暴雨洪涝灾害进行风险评估,并绘制出潍坊市暴雨洪涝灾害风险区划图.结果表明:诸城市中北部、高密市的西南部及安丘的东南部属于高风险区,安丘的东北部、昌邑的南部属于较高风险区,昌乐的大部分、青州的东部、临朐的东北部、安丘的西部属于中风险区,青州西南部、临朐西南部、寿光东北部、昌邑东北部属于低风险区.评价结果与潍坊市的实际情况基本吻合.

Using meteorological data,statistical yearbook data,basic geographic information data,land use data and historical disaster data,we calculated the indexes of flood and waterlogging risk（ FWR） of Weifang and drew its zoning map based on FWR assessment model and GIS technology. The results show that the areas of central and northern Zhucheng,southwestern Gaomi and southeastern Anqiu are the highest risk regions,the areas of northeast- ern Anqiu,southern Changyi are the second highest risk regions,most region of Changle,eastern Qingzhou,north- eastern Linqu and western Anqiu are the median risk regions,while the areas of southwestern Qingzhou,southwest- ern Linqu,northeastern Shouguang and northeastern Changyi are the low risk regions. This assessment results are in good agreement with Weifang＇s reality.
