通过搜集、整理历史资料，选取1636-1949年共314年，并结合SPSS、 EXCEL软件数据分析与ArcGIS图像处理功能，对广西北部湾地区旱涝灾害的等级序列、时间特征、空间特征以及成因进行研究。结果表明：1）1636-1949年间广西北部湾地区共发生大小洪涝灾害456次，平均每0.69年发生1次；干旱灾害400次，平均每0.79年发生1次。2）该地区洪涝灾害主要分布在该地区中部与北部，旱灾主要分布在该地区中部、西部、北部。3）根据旱涝灾害的等级序列可知，2级偏旱略多于1级旱；5级涝多于4级偏涝；灾害以涝灾为主。4）该地区旱涝灾害由地形地貌、人类活动、气候因子共同影响。

By interpreting and analyzing historical data , as well as the combination of data processing and image manipulating functions of SPSS , EXCEL and ArcGIS , the temporal and spatial features , grade series and formation cause of drought and flood disasters , during 1636 and 1949 , in the Beibu Gulf Region of Guangxi are studied .The results shows that there were all together 456 flood disasters occurred during the period , which means 0.69 time per year or 1 time every 0.79 year.In addition , flood disasters mainly occurred in the middle and northern parts of the study area , drought disasters mainly occurred in the middle , northern and western parts .According to the grade series , the frequen-cy of drought disasters at the second grade is higher than at the first grade , the frequency of flood dis-asters at the fifth grade is higher than at the fourth grade .Within the area , flood is the primary disas-ter.Flood and drought disasters were caused by the combination of climatic , human and physical geo-graphical factors .
