黑龙江省旱涝灾害农业气候指标及地理分布区划

AGRICULTURAL CLIMATE INDEX AND ZONATION OF DROUGHT AND WATERLOGGING IN HEILONGJIANG PROVINCE

作者根据水分平衡原理，在考虑水分供应和植物蒸散的基础上，研究了符合黑龙江省实际的农作物旱涝灾动态指标，提出用月气象资料计算旱涝起止日期的模型和计算公式，并制作了黑龙江省春旱区划、春涝区划、夏涝区划和综合旱涝区划。

According to the principle of water balance,on the base of calculating water supply and ET the Agriculture climate dry and waterlogging indexes were studied.These indexes varied with different crop growing periods in Heilongjiang.The Agriculture Climate zonation of dry and waterlogging was made according to the frequency of dry and waterlogging in each season.The zonation includes four types i.e. spring dry,spring waterlogging,summer waterlogging,and comprehensive dry and waterlogging.
