目的 研究分析影响食物中毒发生以及可能存在食物中毒隐患的餐饮卫生投诉事件的因素。方法 对青岛市重点城区14家街道办事处餐饮单位2002—2004年食物中毒以及卫生投诉事件进行收集分析，并利用地理信息系统（GIS）研究其空间分布。使用NCSS Data统计软件对可能与餐饮单位食品卫生事件发生相关的因素进行统计学研究，并在ARCVIEW3．2a软件中将各个街道办事处有关信息标记到电子地图上，直观地反映3年间不同区域食品卫生事件的空间分布。结果 气温、气湿以及日照时数是影响食物中毒发生的重要因素，餐饮单位卫生管理状况、收入情况以及卫生设施配备与餐饮投诉发生明显相关，餐饮单位平均客流量以及区域流动人口数与单位卫生管理合格率相关。结论 应用GIS可较为方便、直观地对不同区域餐饮业食品卫生状况进行分析描述。
