摘要
作者以淮阴市历年的雨涝、干旱实况为依据，参考农业、水利部门统计的受灾面积、防洪排涝能力、农作物不同生育期的需水量等因素，按季节分析雨涝、干旱灾害与雨量关系，确定年季不同级别的旱涝指标。其分析结论是：40多年来旱涝灾年发生的频数超过正常年，且涝灾多于旱灾，重于旱灾；但秋旱多于秋涝。
築ased on the data about waterlogging and drought, referring agricultural disasters,capability of preventing flood and developing feature of crops,the indexes on drought and waterlogging are determined for each season. The results show that,in the last 40 years or more,disastrous years exceeded the normal, and damages caused by waterlogging are more serious than that by drought. It is of momentous significance for adopting measures of defense,avoiding darnage and developing agriculture to understand and master the weather/climate regularity on drought and waterlogging.
