摘要
利用景区水库的降水和水文观测历史记录,采用对邻近气象测站测值进行同比气候差订正的方法来弥补少量资料的断缺,以形成完整的历史资料链条。运用与周边气象站对比分析的统计方法,对景区降水、泉瀑汇流水量的年度分布、多年变化趋势进行分析,结果表明:云台山景区降水资源较周边地区显著偏多,降水主要集中在汛雨阶段,多局地性的暴雨、大暴雨日;景区库区来水量分为丰、平、枯年,与汛期降水关系密切,其降水有明显的年代际变化特征,近期正在向少雨年代过渡。
Based on historical records of scenic reservoir precipitation and hydrological observation,the climatic correction method for neighboring weather stations values in the same period was adopted to make up the lack of data chain,and formed a complete historical data.The scenic precipitation,annual distribution of spring-fall confluence water and multi-year trends were discussed by use of statistically comparative analysis method with weather stations around.The results showed that precipitation resources of Yuntaishan scenic area were significantly more than the surrounding areas,precipitation mainly concentrated in the rain flood stage,more local rainstorm days,heavy rainstorm days.Scenic rainfall has obvious decadal changes characteristics,coming-water in the reservoir area was divided into abundance,flat,dry years,and closely related with the flood season,the current period is to few rain age transition.
