| 摘 要： | 帕默尔旱度模式是评估干早严重程度的重要模型,20世纪引入中国后,安顺清等人相继进行了修正,但是多采用的是单个站点数据进行运算,在研究大尺度的区域时则不适用,文章将各研究区站点数据平均整合,并以辽宁省范围内辽河流域片的7个代表性区域进行建模,以海滦河流域、淮河流域、黄河流域、长江流域的23个代表性区域相关资料为权重因子进...

| Abstract: | The Palmer Drought Severity Model is an important model to estimate the severity of drought.After being introduced into China in the 20th century,a series of corrections have been made by An Shunqing,etc.This method is used to the operation by the data from single site.We averaged the data of single site and then integrated them.We constructed the model with seven typical sites of Liaohe basin in Liaoning.And we used the data gained from other 23 stations from the Haihe-Luanhe River basin,the Huaihe River b... |
