摘　　要：利用2007-2015年山东省闪电监测资料,对比分析了山东省两种不同地表类型区域即黄河三角洲平原和泰山地区的闪电活动特征,得到以下结论:1山地发生的地闪总数比平原多23.20%;2平原地区正闪比例为2.07%,泰山地区为1.50%;3平原地区的平均地闪密度值为1.39次·km^(-2)·a^(-1),山地为1.71次·km^(-2)·a^(-1);4平原和山地地闪日变化曲线都呈现出单峰单谷的趋势;5平原地区雷电流平均强度比山地地区高10.30%.Lightning detection data of Shandong Province from 2007 to 2015 was used to make comparative analysis of the lightning activity characteristics between two different land cover types,namely the Yellow River delta plain and the Mountain Tai area,through which the following conclusion was reached：① The number of times that lightning occurred in mountainous area was 23.20%,which was higher than that in the plain;② the ratio of positive lightning was 2.07%in the plain,while that in the Mountain Tai area was 1.50%;③ the value of lightning density in the plain was 1.39 fl·km^-2·a^-1,while that in the mountainous area was 1.71 fl·km^-2·a^-1;④the lightning diurnal variation curve in both the plain and mountainous area demonstrated a trend of single peak and valley;5 average intensity of lightning current in the plain was 10.30% which was higher than that in the mountainous area.
